UGC NET Paper 1: Held On 19 June 2023 Shift 1 (Previous Year Paper)

Given:

Number of teaching female = Number of Non-Teaching female 

Number of teaching males = Teaching females + 5

Total Female employees = 82

Calculation:

Non-teaching females = 82 ÷ 2 = 41

Non-teaching males = 142 - (41 + 5) = 96

⇒ Required Difference = 96 - 41 = 55

∴ The difference between non-teaching males and non-teaching females is 55.

Given:

In college A:

Number of non-teaching females = 2 + (0.5 × number of teaching females)

Calculation:

In College A,

Non-teaching male = 526 - 325 = 201

Let, Non-teaching female = m

⇒ m = 2 + (0.5 × (756 - 526 - m))

⇒ m = 2 + 115 - 0.5m

⇒ 1.5m = 117

⇒ m = 78 

Required Difference = 201 - 78 = 123

∴ The difference between non- teaching males and non-teaching females is 123.

Given:

The number of teaching males in College D = 46

124 males from college A of whom 62 are non-teaching, are transferred to college D. 

Calculation:

Initially, Non-teaching males in college D = 142 - 46 = 96

New number of non-teaching males in college D = 96 + 62 = 158

∴ New number of non-teaching males in college D is 158.

Given:

Females in college C = 147 + Females in College A 

Sum of teaching males and teaching females in College C = 115

Calculation:

Total females in college C = 147 + (756 - 526) = 377

Total males in College C = 159

Sum of non-teaching males and non-teaching females in college C = 377 + 159 - 115 = 421

∴ Sum of non-teaching males and non-teaching females in college C is 421.

Given: 

In college B, the number of non-teaching males = 26 + teaching males

Number of non teaching males - non teaching females = 122

The number of males > number of females

Calculation:

Number of male employees = 215 + (215 + 26) = 456

Number of female employees = 254 + (215 + 26 - 122) = 373

Total Employees  = 456 + 373 = 829

∴ The number of employees is 829.

The answer is: Both Statement I and Statement II are incorrect.

Important PointsStatement I: A dependent variable can never be dichotomous.

• A dependent variable is what you measure in the experiment and what is affected during the experiment.
• The dependent variable responds to the independent variable. It is called dependent because it "depends" on the independent variable.
• A dependent variable could certainly be dichotomous.
• For example, if you're conducting an experiment to determine whether a certain type of tutoring increases students' passing rates on a test, the dependent variable (whether the student passed or not) is dichotomous because it has only two possible values: "passed" or "not passed".
• Thus, this statement is incorrect.

Statement II: An independent variable is always dichotomous.

• An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.
• An independent variable can be dichotomous, but it can also be polytomous (having more than two possible values), or even continuous.
• For instance, in an experiment investigating the effect of temperature on plant growth, the temperature is the independent variable.
• However, temperature could take on a range of values, not just two, thus it would not be dichotomous in this case. Therefore, this statement is also incorrect.

Both statements are incorrect because they make absolute claims ("never" and "always") about the characteristics of dependent and independent variables that are not supported by the flexibility and range of these variables in experimental design.

The term used to describe human communication behavior related to personal space is "Territoriality."

Important Points"Territoriality" in the context of human behavior is a concept derived from animal behavior studies, where territory is a space an animal defends against others of its species.

• In human social interactions, while we don't typically physically defend our space, we still have an innate understanding and expectation of personal space boundaries.
• This concept of territoriality is connected to the term "proxemics," which was introduced by anthropologist Edward T. Hall in 1963.
• Proxemics is the study of human use of space and the effects that population density has on behavior, communication, and social interaction.

Hall identified four zones of personal space:

Intimate distance:

• This is for embracing, touching, or whispering and ranges up to 18 inches apart.

Personal distance:

• This is for interactions among good friends or family members and ranges from 1.5 feet to 4 feet apart.

Social distance:

• This is for interactions among acquaintances and ranges from 4 to 10 feet apart.

Public distance:

• This is for public speaking and ranges from 10 feet to infinity.

Everyone's personal space boundaries vary based on cultural background, personal preference, situational factors, and the relationship between the people interacting. When someone else invades our personal space, we may feel uncomfortable, anxious, or threatened.

• This reaction is a demonstration of our sense of territoriality.
• It's important to note that our virtual era has introduced new complexities to our understanding of personal space and territoriality, with digital spaces now an area of focus in the field of proxemics.

The changes in participants due to psychological factors such as boredom and fatigue over time would constitute a "Maturation Threat" to internal validity.

Important Points

Internal validity is about the degree to which an experiment is sound and allows for the researcher to have confidence in the causality of the results.

• Maturation threats to internal validity occur when the observed effects in an experiment might be due to the natural maturation of participants (e.g., growing older, getting tired, becoming bored) and not due to the experimental manipulations.

Therefore, the answer   is: Maturation threat

Additional Information

Maturation Threat:

• As I've mentioned, this occurs when changes in participants happen naturally over time.
• It's called a "maturation" threat because people mature and change over time, and these changes might impact the results of the study if it is a longitudinal study (i.e., a study conducted over a long period of time).
• This could include psychological changes like boredom and fatigue, or physical changes like aging.

History Threat:

• This involves changes or events that happen in the participants' environment or the world at large during the study, that are not part of the intervention or manipulation, but which may affect the outcome.
• For instance, a sudden news event could influence people's responses in a study if it is related to the topic of the research.

Selection Threat:

• This pertains to how participants are chosen for different groups within a study.
• If the groups are not equivalent at the start of the study, then observed differences at the end might be due to this initial inequivalence, rather than the intervention.
• For instance, if one group of participants in an educational study is made up of honors students, and the other group is not, then differences in outcomes might be due to initial ability, not the teaching method being tested.

Instrumentation Threat:

• This happens when the tools (instruments) or procedures used to measure the outcomes in the study change over time.
• If the same outcome is measured differently at different times, it can appear that a change has occurred when it has not.
• For example, if a researcher becomes more skilled at conducting an interview, or if a questionnaire is changed part way through a study, these could constitute instrumentation threats

The correct answer would be "A is false but R is true."

Important Points

Assertion A: Hydrofluorocarbons (HFCs), replacements of ozone depleting substances chlorofluorocarbons (CFCs) were also decided to be phased out during the Copenhagen-1992 conference.

• This assertion is incorrect.
• The Copenhagen Amendment to the Montreal Protocol in 1992 did strengthen the control over several ozone-depleting substances, but it did not include any decisions about HFCs.
• HFCs are not ozone-depleting substances, but they are potent greenhouse gases.
• The decision to phase down the production and consumption of HFCs was taken much later, during the 28^th Meeting of the Parties to the Montreal Protocol held in Kigali, Rwanda, in October 2016.
• Hence, the claim about the Copenhagen-1992 conference is incorrect.

Reason R: HFCs have shorter lifetime than CFCs and contain no Chlorine and bromine.

• This statement is correct.
• HFCs, or Hydrofluorocarbons, do have a shorter atmospheric lifetime than chlorofluorocarbons (CFCs).
• Also, HFCs do not contain any chlorine or bromine. CFCs were a problem because they released chlorine and bromine when they broke down in the atmosphere, which led to the depletion of the ozone layer.
• HFCs, while still potent greenhouse gases that contribute to global warming, do not have this same destructive effect on the ozone layer because they lack chlorine and bromine. Therefore, this statement is correct

The aim of the National Education Policy (NEP), 2020, as proposed by the government of India, is to increase the Gross Enrolment Ratio (GER) in higher education to 50% by 2035.

Important Points

The Gross Enrolment Ratio (GER) in higher education in India is calculated as the number of students enrolled in higher education institutions (HEIs) as a percentage of the population of the group which is officially defined as eligible for higher education.

• The aim to increase the GER to 50% by 2035 is a part of broader goals of the NEP 2020, which include universalization of education from pre-school to secondary level, extension of Right to Education Act 2009 to cover children of ages 3 to 18, and major reforms in higher education among others.

So, the answer to your question is: 50%

Additional Information

• The policy also envisions a restructuring of higher education institutions into three types - Research Universities, Teaching Universities, and Autonomous degree-granting colleges, all of which would have autonomy to innovate on matters of curriculum, pedagogy, and assessment.
• The NEP 2020 also advocates the use of technology in education, making education more student-centric, fostering critical thinking, and reducing the content load in the curriculum.
• Overall, the objective of increasing the GER to 50% in higher education by 2035 is part of the NEP's broader aim to overhauling the Indian education system, making it more modern, inclusive, and quality-oriented.

The correct statement about the Internet of Things (IoT) that can create a smart environment is:The Internet connectivity is not essential for an IoT setup to function.

Important Points

The Internet connectivity is not essential for an IoT setup to function:

• This statement is correct. While many IoT applications rely on internet connectivity to enable communication and data transfer between devices and systems, it is not always a requirement.
• Some IoT setups can function in localized environments without an internet connection, using local networks or communication protocols.

Additional Information

Every IoT device or item must be connected using UTP cables:

• This statement is incorrect. IoT devices can be connected using various types of connectivity options, including wired (such as UTP cables) and wireless connections like Wi-Fi, Bluetooth, or cellular networks.
• IoT environments cannot be monitored and controlled remotely: This statement is incorrect.
• One of the key features of IoT is the ability to monitor and control devices and systems remotely.
• Through internet connectivity, users can access and manage IoT devices, sensors, and software applications from anywhere, enabling remote monitoring and control.

Modern smart mobile phones cannot be connected to an IoT setup: This statement is incorrect. Smartphones can be an integral part of an IoT setup. Mobile apps can serve as user interfaces to monitor and control IoT devices, receive notifications, and access data collected by the IoT system. Smartphones can connect to IoT devices using various wireless technologies like Wi-Fi, Bluetooth, or cellular networks

The correct answer is the Montreal protocol.

“Perhaps the single most successful international environmental agreement to date has been the Montreal Protocol, in which states accepted the need to phase out the use of ozone-depleting substances.”​

Key Points 

Montreal Protocol:

• The Montreal Protocol on Substances that Deplete the Ozone Layer was adopted in 1987 and is considered one of the most successful international environmental agreements.
• The protocol aimed to protect the Earth's ozone layer by phasing out the production and use of substances known as ozone-depleting substances (ODS), such as chlorofluorocarbons (CFCs) and halons.
• It has been successful in significantly reducing the production and consumption of ODS and has played a vital role in the recovery of the ozone layer.

Additional Information Rio Summit (Earth Summit):

• The Rio Summit, officially known as the United Nations Conference on Environment and Development (UNCED), took place in Rio de Janeiro, Brazil, in 1992.
• The summit resulted in several important agreements, including the adoption of the United Nations Framework Convention on Climate Change (UNFCCC), the Convention on Biological Diversity (CBD), and the Rio Declaration on Environment and Development.

Kyoto Protocol:

• As mentioned earlier, the Kyoto Protocol is an international agreement that aims to combat climate change by reducing greenhouse gas emissions.
• It was adopted in 1997 and came into force in 2005.
• The protocol set binding emission reduction targets for developed countries, which were collectively required to reduce their emissions by a specified percentage below their 1990 levels.

Paris agreement:

• The Paris Agreement is an international accord that aims to address the global challenge of climate change.
• It was adopted on December 12, 2015, at the 21^st Conference of the Parties (COP21) to the United Nations Framework Convention on Climate Change (UNFCCC) held in Paris, France.
• The agreement came into force on November 4, 2016, after being ratified by a sufficient number of countries.

The most appropriate answer is statement I is correct but statement II is incorrect.

Important Points

Statement I: Biodiesel can be created from vegetable oils and animal fats.

• Biodiesel is a renewable fuel that can be produced from various feedstocks, including vegetable oils (such as soybean oil, rapeseed oil, or palm oil) and animal fats (such as tallow or lard).
• These feedstocks undergo a process called transesterification to convert them into biodiesel.

This statement is correct.

Statement II: Biodiesel viscosity is significantly lower than that of petroleum diesel.

• The density of biodiesel is approximately 6.15% higher than that of diesel fuel.
• The viscosity of biodiesel is higher than that of diesel fuel by 12.5%.
• The lower heating value is roughly 9.25% lower than that of diesel fuel.

Hence, statement II is incorrect.

Therefore, statement I is correct but statement II is incorrect.

The correct answer is: D and E only

Biological treatment processes in wastewater management are primarily employed to treat and remove organic pollutants from wastewater, including both colloidal substances and soluble organic compounds. These processes leverage bacteria and other microorganisms to consume these organic compounds, converting them into simpler substances which are easier to manage and less harmful to the environment.

 Key Points

Role of Biological Processes:

• The central role of biological processes in wastewater treatment is to break down and remove organic matter.
• The organic matter in wastewater typically includes both soluble and colloidal substances.
• Soluble organic compounds are dissolved in the water, while colloidal substances exist as small, suspended particles.

Soluble Organic Compounds:

• These are composed of organic matter that is dissolved in the water.
• These compounds are typically consumed by bacteria and other microorganisms in a process called biological oxidation.
• This process transforms the organic compounds into carbon dioxide, water, and additional biomass.

Colloidal Substances:

• Colloidal organic matter, which is made up of small particles suspended in the water, can also be removed by biological processes.
• Certain types of bacteria and other microorganisms are able to consume these particles, reducing their concentration in the wastewater.

Therefore, in the context of wastewater treatment, biological processes mainly target the removal of both colloidal substances (D) and soluble organic compounds (E). 

Additional Information

• While biological processes can also help reduce the levels of bacteria, fungi, and some suspended solids, these are not the primary targets of biological treatment.
• Other methods, such as mechanical and chemical treatments, are typically used in combination with biological processes to more effectively remove these other contaminants.

The correct answer is: B, C, and D only

Important Points

B. Blu-ray disk: Blu-ray disks are an optical disc storage medium.

• They are used for various data storage and video playback purposes.
• Blu-ray disks need a dedicated Blu-ray disk reader/writer to access the data stored on them.
• To access the information on a Blu-ray disk, it must be physically inserted into the Blu-ray drive of the system.
• Once the reading/writing operation is done, the disk is generally removed and stored safely.
• Thus, Blu-ray disks are considered offline storage devices.

C. DVD/CD:

• DVDs (Digital Versatile Discs) and CDs (Compact Discs) are another form of optical disc storage media, similar to Blu-ray disks but with lesser storage capacities.
• They are used to store data, audio, and video files.
• To access the data stored on a DVD or CD, the disc needs to be physically inserted into the DVD/CD drive of the system. Just like Blu-ray discs, DVDs and CDs are also typically removed and stored after usage, making them offline storage devices.

D. USB memory stick:

• USB memory sticks, also known as flash drives or thumb drives, are portable storage devices that use flash memory to store data.
• These devices connect to the system through a USB (Universal Serial Bus) port. While a USB memory stick can remain plugged into a system, thereby providing immediate access to its stored data, they are primarily designed to be portable.
• This means they are typically removed from the system after data transfer is completed.
• Because of this, USB memory sticks are usually considered offline storage devices, despite their ability to function similarly to online storage when left connected to a system.

In contrast, the Hard Disk Drive (A) is an example of online storage because it's typically installed inside the computer and constantly connected, providing continuous and immediate access to its stored data. As such, it is not considered offline storage and is not part of the correct answer

The correct answer is Culture.

Important Points

• The concept of the "Culture" is a key idea from the Frankfurt School, particularly associated with the work of Jürgen Habermas.
• The Frankfurt School was a group of critical theorists associated with the Institut für Sozialforschung (Institute of Social Research) which was located first at the University of Frankfurt (1923–1933), then in Geneva, Switzerland (1933–35), Columbia University in New York (1935–1949), and finally back at the University of Frankfurt, from 1949 to present.
• Some of the theorists associated with what became known as the Frankfurt School included Max Horkheimer, Theodor Adorno (née Wiesengrund), Herbert Marcuse, Walter Benjamin, Erich Fromm, Leo Lowenthal, and Friedrich Pollock.
• Felix Weil began the Institute of Social Research in 1923. The theoretical basis of the Institute was Marxist, to no small degree because of Carl Grünberg, who served as director from 1923-1930. Max Horkheimer succeeded Grünberg as director and served in that capacity until 1960, when Theodor Adorno became director, until his death in 1969.
• These theorists were all associated with the Institute in the 1920s, except for Marcuse, who began working with the Institute in 1932. From the late 1950s Jürgen Habermas would be involved with the Institute, but for a number of reasons his work is often considered separate from that of the Frankfurt School.
• The Institute for Social Research continues to operate at the University of Frankfurt, but what is known as the Frankfurt School did not extend beyond the theorists associated with it.

The other options - custom, convention, and public sphere- while important to communication and social interaction, don't encapsulate the communicative structure reflecting social order as conceptualized by the Frankfurt School.

The correct answer is Statement I is correct but Statement II is incorrect.

Important Points

Statement I: According to the classical Indian School of logic (Nyaya), all fallacies are material fallacies.

This means that Nyaya considers fallacies as errors or mistakes in reasoning that occur due to the content or material of the argument, rather than the form or structure of the argument.

Statement II: Nyaya syllogism is deductive-inductive but not formal-material. This statement seems to be incorrect based on the understanding of Nyaya's syllogism.

In Nyaya, syllogism is typically considered to be a type of formal inference. It follows a strict structure with five members (avayava) and seven limbs (karana). The Nyaya syllogism is formulated in a manner similar to classical Western deductive logic, with specific rules governing the validity of inference.

Therefore, in the light of the above statements, the correct answer would be:

Option (B): Statement I is correct, but Statement II is incorrect.

The correct answer is: A, B, and E only

Important Points

A. Self-monitoring:

• In self-directed learning, an individual needs to keep track of their own learning progress.
• They need to regularly check if they are understanding the concepts, if they're meeting their learning goals, and identify areas where they might be struggling.
• This process is called self-monitoring.
• It helps learners adjust their learning strategies as needed and maintain their progress towards their goals.

B. Taking ownership of learning:

• This is another key feature of self-directed learning.
• Taking ownership means that the learners decide what they want to learn, set their own learning goals, and determine how they'll achieve those goals.
• They take responsibility for their successes and failures, and they understand that their learning outcomes are a direct result of their own efforts.
• This level of ownership encourages engagement and motivation, as the learner feels a personal stake in their learning process.

E. Extension of learning:

• Self-directed learning is not limited to what is taught in the classroom or within a prescribed curriculum.
• Learners extend their knowledge beyond these boundaries, pursuing further learning in areas they are interested in.
• They might read additional books, attend webinars, participate in online discussions, or take up projects on topics that intrigue them.
• This extension of learning is self-directed, as it's guided by the learner's own interest and curiosity, and it allows for a deeper and more personal engagement with the subject matter.

The correct response is A - III, B - IV, C - I, D - II.

Key Points

The correct answer is: B, A, D, C.

Important Points

In terms of decreasing extension, the order is as follows:

The extension of terms refers to the scope or the number of objects that fall under each term. To arrange the given group of terms in order of decreasing extension, we need to consider the broader and more inclusive terms first, followed by the more specific and narrower terms.

The correct order of decreasing extension is as follows:

B. Animal (The term "Animal" is the broadest term, encompassing all living animals, including mammals, birds, reptiles, etc.)

A. Mammal (The term "Mammal" is more specific than "Animal" as it refers to a class of warm-blooded vertebrates with mammary glands, hair or fur, and typically giving live birth.)

D. Feline (The term "Feline" is even more specific than "Mammal" and refers to a subgroup of mammals belonging to the Felidae family, which includes cats.)

C. Tiger (The term "Tiger" is the most specific term in this group, referring to a particular species of feline.)

So, the correct answer is:

Option (B): Animal, Mammal, Feline, Tiger

The correct option is: Poly chlorinated Biphenyl

Important Points

The full form of PCB, an air pollutant, is Poly chlorinated Biphenyl. PCBs are a group of synthetic organic chemicals that were commonly used in various industrial applications, such as electrical equipment, coolants, and lubricants.

• Due to their persistence in the environment and potential health risks, PCBs are considered hazardous pollutants and have been largely banned or restricted in many countries.

Additional InformationPCBs are a group of chlorinated organic compounds consisting of two benzene rings connected by a central carbon-carbon bond. They belong to the family of organochlorine compounds.

Historical Use:

• PCBs were first synthesized in the late 1800s and became widely used in various industrial applications throughout the 20^th century.
• They were valued for their heat resistance, chemical stability, and electrical insulating properties, which made them suitable for use in electrical transformers, capacitors, and other electrical equipment.

Environmental Impact:

• Despite their useful properties, PCBs are persistent in the environment and can accumulate in soil, water, and living organisms.
• Due to their chemical stability, they do not readily break down, leading to long-term environmental contamination. PCBs are considered toxic and pose significant health risks to both humans and wildlife.

Health Risks:

• PCBs are known to be toxic and have been linked to various adverse health effects in humans, including reproductive disorders, developmental problems, and increased risks of certain cancers.
• These health risks led to the widespread ban or restriction of PCBs in many countries.

The correct answer is Both A and R are correct and R is NOT the correct explanation of A.

Important PointsAssertion A: Deductive arguments are indeed either invalid or valid.

• A deductive argument is valid if the conclusion logically follows from the premises.
• It is invalid if the conclusion does not logically follow from the premises.

Reason R: A valid deductive argument that also has all true premises is indeed called a "sound" argument.

• However, this does not explain why deductive arguments are either invalid or valid.
• That's a function of the structure of the argument itself, not whether it's sound or unsound.

So, the correct answer from the options given is:

Both A and R are correct and R is NOT the correct explanation of A

Additional Information

Deductive Argument:

• This is a type of logical argument that attempts to show its conclusions as necessarily following from its premises.
• In other words, if the premises are true, then the conclusion must also be true.
• A common form of a deductive argument is a syllogism, like:

Premise 1: All men are mortal.

Premise 2: Socrates is a man.

Conclusion: Therefore, Socrates is mortal.

In this example, if both premises are true (and they are), the conclusion must also be true.

Validity:

• In logic, an argument is valid if the conclusion logically follows from the premises.
• It's important to note that validity doesn't concern whether the premises or conclusion are actually true or false, but whether the argument holds the correct logical form.
• Even with false premises, an argument can be valid if the conclusion would logically follow if the premises were true.

Soundness:

• A deductive argument is sound if it is both valid (the conclusion logically follows from the premises) and the premises are true.
• So, a sound argument guarantees the truth of the conclusion.
• In Reason R from your question, it correctly states the definition of a sound argument.
• However, this doesn't directly explain why deductive arguments are either invalid or valid, as stated in Assertion A.
• The validity of a deductive argument is determined by whether its conclusion logically follows from its premises, not by whether it's sound or not.

The logic followed here is:

Logic → Code = (Sum of the positional values) + (Number of letters)

Let's check as per the logic,

TABLE → (20 + 1 + 2 + 12 + 5) + (5) = 40 + 5 = 45

Similarly,

CHAIR → (3 + 8 + 1 + 9 + 18) + (5) = 39 + 5 = 44

Hence, the correct answer is "44".

Check all the given options,

1). d c c *b * b a a a \ d c c c \ b a a a → No pattern is formed.

2). d c c c \ b a a a \ d c c c \ b a b a → No pattern is formed.

3). d c c c \ b a b a \ d c c c \ b a a a → No pattern is formed.

4). d c c c \ b a a a \ d c c c \ b a a a → Pattern is formed, first is followed by it's previous alphabet by three times according to the English alphabet series.

Hence, the correct answer is "c a c a".

NOTE: We have updated the question as there is some error with this and in the provided PYP PDF, it's answer is dropped.

The correct answer is Raleigh Commission​.

Important PointsRaleigh Commission:

• The Raleigh Commission, formally known as the Indian Universities Commission, was established in 1902.
• The commission was headed by Sir Thomas Raleigh, who was the Law Member of the Governor-General's Executive Council at that time.
• The commission was tasked with investigating the condition and prospects of universities in India, with a focus on teaching and research.
• The Raleigh Commission recommended several changes to higher education in India, including the closure of substandard colleges.
• This was done with the aim of raising the overall standard of higher education in the country, ensuring that students received quality education that would prepare them adequately for their future careers.

Additional Information

Sadler Commission:

• The Sadler Commission, officially known as the Calcutta University Commission, was established in 1917 during the British colonial era in India.
• It was formed to investigate and make recommendations on the state of education, particularly higher education, in British India.

Hunter Commission:

• The Hunter Commission, officially known as the Indian Universities Commission, was established in 1882 during the British colonial period in India.
• It aimed to examine the state of higher education in India and make recommendations for its improvement.

Hartog Committee:

• The Hartog Committee, officially known as the Indian Universities Committee, was formed in 1929.
• Its purpose was to review the state of university education in India and propose reforms.

The correct answer is: Observational research.

Important Points

Observational research refers to the study of human and non-human behavior in their natural environment without any manipulation of variables.

• In this type of research, the researcher observes and records behaviors, interactions, and phenomena as they naturally occur, without intervening or manipulating any variables.
• Observational research allows for the collection of data in real-world settings, providing valuable insights into natural behaviors and relationships between variables.

Additional InformationQuasi-experimental research:

• Quasi-experimental research is a type of research design that resembles experimental research but lacks random assignment to treatment and control groups.
• In quasi-experimental studies, researchers manipulate an independent variable but cannot randomly assign participants to groups due to practical or ethical constraints.
• This type of research is used to investigate cause-and-effect relationships in settings where randomization is not feasible.
• Unlike observational research, quasi-experimental research involves manipulating variables, albeit without random assignment.

Subjective research:

• The term "subjective research" is not a widely recognized term in the field of research methods.
• However, if we interpret it as research that involves subjective experiences, opinions, or interpretations, it could refer to qualitative research methods such as interviews, surveys, or focus groups.
• These methods aim to gather subjective perspectives and insights from participants.
• However, it is important to note that subjective research can also be conducted within other types of research designs, such as experimental or observational studies.

Anthropometric research:

• Anthropometric research focuses on the measurement and study of human body dimensions, physical characteristics, and proportions.
• It involves collecting data on various body measurements such as height, weight, body mass index (BMI), limb lengths, and other physical attributes.
• Anthropometric research is often used in fields such as ergonomics, human factors, and healthcare to understand human variations and design products, environments, or interventions that accommodate diverse body sizes and shapes.

In summary, while the correct option for the study of behavior in the natural environment without manipulation of variables is observational research, the other options represent different types of research methodologies and approaches

The correct answer is: Statement I is false but Statement II is true

Important Points

Statement I is false because the Buddhist communication theory is not simple and one-sided.

• Instead, it recognizes the complex nature of communication, acknowledging the interdependence of the communicator and the recipient.
• It also focuses on ethical and moral aspects, implying that the effects of communication should promote well-being and avoid harm.

Statement II is true as the Buddhists indeed understand communication as a social and moral act.

• The Buddhist perspective emphasizes mindful speech, intending to promote truthful, beneficial, and non-harmful communication.
• In this context, communication is more than just the transfer of information—it's a practice deeply intertwined with ethical considerations.

The correct answer is: C, D, and E only

Important Points

C. Body movements of an individual have potential meanings -

• This statement is true.
• As mentioned, kinesics is all about understanding the meaning behind body movements and gestures.
• These movements can convey emotions, attitudes, and reactions, often complementing or even contradicting verbal communication.

D. Kinesics can be subject to systematic analysis -

• This statement is true.
• Researchers can and do systematically analyze body language to understand non-verbal communication. They may observe patterns, study the context, and consider cultural norms to interpret the meanings behind different movements and gestures.

E. A person's body language is part of his social system shared with others -

• This statement is true. Body language, including gestures, postures, and facial expressions, is influenced by social and cultural norms.
• It's a way that individuals communicate with each other within a shared social system.

Additional Information

A. Kinesics does not convey any meaning -

• This statement is false.
• The whole point of studying kinesics is because body movements and gestures do convey meaning.
• They can express a wide range of messages, from interest or disinterest to confidence or anxiety.

B. Kinesics does not reflect the social system of an individual -

• This statement is also false.
• Body language can give clues about an individual's cultural background and social conditioning.
• Different cultures have different norms and interpretations for gestures and body language.

The correct answer is B, C, D and E only

Important Points

The National Policy on Education (NPE), 1986, visualized several changes and improvements for higher education in India.

A. Complete privatisation of higher education - This was not one of the objectives. The policy emphasized the need for public funding for higher education, although it did open up for private participation.

B. Consolidation and expansion of institutions - The NPE did indeed emphasize the consolidation and expansion of institutions to provide increased access to higher education.

C. Training of teachers - The NPE also highlighted the importance of improving the quality of education, which included the need for better training of teachers.

D. Development of autonomous colleges - The policy advocated for increased autonomy for colleges and universities to encourage innovation and improvements in quality.

E. Strengthening of research - The NPE recognized the importance of research and aimed to strengthen research capacity in higher education institutions.

Therefore, options B, C, D, and E were visualized by the National Policy on Education, 1986 vis-a-vis higher education.

The correct answer is D, A, B, C

Important Points

In the context of a computer system, the access speed of various storage components generally follow this order (from fastest to slowest):

D. CPU Registers - CPU registers, being located inside the CPU itself, have the fastest access speed. They are used to store temporary data that the CPU is currently processing.

A. Cache Memory - Cache memory is a smaller, faster type of memory that stores copies of data from frequently used main memory locations. It's slower than CPU registers but much faster than main memory.

B. Main Memory (RAM) - Main memory, or random-access memory (RAM), is slower than CPU registers and cache memory. It temporarily stores data that is currently being used or processed by the CPU.

C. Magnetic Disk (Hard Drive) - The magnetic disk, or hard drive, is the slowest form of memory in this list. It is used for long-term storage of data. It's slower because it uses mechanical parts to read and write data, unlike the other components listed, which are electronic.

The correct answer is Both Statement I and Statement II are true

Important Points

Both Statement I and Statement II are correct. They perform the same operation in different ways.

Statement I: The formula =COUNTIFS(C2:C101, "0") counts all customers who get discounted price.

• The COUNTIFS function in Excel counts the number of cells in a range that meet multiple criteria.
• In this case, the criteria is "0", which represents the discounted price. So, it's counting all customers who get a discounted price.
• The COUNTIFS function is more flexible as it allows for multiple criteria, but in this instance, it's used with just one criterion, so it behaves like the COUNTIF function.

Statement II: The formula =COUNTIF(C2:C101, "=0") Counts all customers who get discounted price.

• The COUNTIF function in Excel counts the number of cells within a range that meet the given condition.
• Here, the condition is "=0", which is equivalent to "0" in Statement

I. This formula also counts all customers who get a discounted price.

So, both formulas are equivalent in their functionality in this context, and both correctly count the number of customers who get a discounted price.

Concept used:

Time = Distance/Speed

Calculation:

Let's assume that the total distance be D, so the speed of train A = D/4 and the speed of train B = D/3.5

Now, two trains are moving in opposite directions, relative speed be (D/4 + D/3.5)

Time takes to meet = \(\frac{D}{\frac{D}{4}+\frac{D}{3.5}}\) = \(\frac{D}{\frac{D}{4}+\frac{2D}{7}}\) = \(\frac{28D}{15D}\) = 28/15 hr = 112 min

So, two trains cross each other at 6 AM + 112 min = 7 AM + 52 min = 07 : 52 AM

∴ The correct answer is 07 : 52 AM

The correct answer is Existential fallacy

**Important PointsThe argument "All household pets are domestic animals.

No unicorns are domestic animals. Therefore some unicorns are not household pets" commits the Existential Fallacy.**

• The Existential Fallacy is a formal fallacy. In a categorical syllogism, if both premises are universal (making a claim about every member of a category), but the conclusion is particular (making a claim about one or some members of a category), then the argument commits the Existential Fallacy.
• In the argument you provided, both premises ("All household pets are domestic animals" and "No unicorns are domestic animals") are universal, but the conclusion ("Therefore some unicorns are not household pets") is particular.
• This argument assumes that unicorns exist, which is not stated in the premises.

So, the answer is:

Existential fallacy

The correct answer is Statement I is true but Statement II is false

Important Points

Statement I: The earliest British policy on education in India, often associated with the dispatch from Charles Wood (also known as Wood's Despatch)

• in 1854, did aim to withdraw the state from responsibility for higher education, leaving it in private hands.
• The British believed that higher education was not for the masses but rather for the elite who could afford it. Hence, this statement is true.

Statement II: The British policy did not support the idea of the mother tongue as the medium of instruction as against English.

• The British aimed to create a class of Indians who would be "Indian in blood and color, but English in tastes, in opinions, in morals and in intellect".
• This was done primarily by promoting English as the medium of instruction in schools. Hence, this statement is false.

D. Moodle:

• Moodle is a Learning Management System (LMS) that offers a flexible and customizable platform for educators to create and manage online courses, assignments, and assessments.

Additional Information

A. Kahoot:

• Kahoot is not a Learning Management System (LMS). It is an interactive platform used for creating and playing learning games, quizzes, and surveys

C. Canva:

• Canva is not a Learning Management System (LMS).
• It is a graphic design tool used for creating various visual content, such as presentations, social media graphics, posters, and more.

E. Padlet:

• Padlet is not a Learning Management System (LMS). It is an online collaborative tool that allows users to create virtual bulletin boards and collaborate with others by adding various multimedia content.

The correct answer is  B and D only.

The correct penalty for committing plagiarism of level 3 as per UGC Regulations 2018 on Plagiarism is:

Student's registration for that program shall be cancelled.

Important Points

Penalties will be given to students according to the decision of the Plagiarism Disciplinary Authority (PDA). The punishments given to students for plagiarism for different levels of severity are given below:

• Level 1 (10%-40%)– the student will not be given any mark or credit and revised script must be resubmitted within a stipulated time period which does not exceed 6 months.
• Level 2 (40%-60%)– the student will not be given any mark or credit and the revised script is to be resubmitted between 1 year and 18 months.
• Level 3 (above 60%)– the student will not be given any mark or credit and their registration for that course will be canceled.
• If a student repeats such act of plagiarism then the punishment will be for the next level to the one previously committed. In cases where the highest level of plagiarisation occurs then the punishment remains the same and the registration will be canceled.

Additional Information

Plagiarism is considered a form of academic misconduct because it undermines the principles of academic integrity, honesty, and originality. In educational settings, it can result in severe consequences, including failing grades, academic penalties, or even expulsion, depending on the institution's policies.

To avoid plagiarism, students, researchers, and creators are encouraged to:

• Properly cite all sources used in their work, including direct quotes, paraphrased content, and any ideas or information derived from other sources.
• Use quotation marks or indentation for verbatim quotes and provide in-text citations or footnotes to acknowledge the original author or source.
• Give credit to the original creator when using images, diagrams, or any non-textual material that is not their own.
• Understand the difference between common knowledge and specific information that requires citation.
• Use plagiarism detection tools to check their work for unintentional instances of plagiarism.
• Academic institutions often provide guidelines and resources on how to avoid plagiarism and promote academic integrity.
• It is crucial for individuals to maintain ethical practices and uphold the principles of honesty and respect for others' intellectual contributions.

The argument presented takes a fact about a group or a set (in this case, the Swiss population) and erroneously applies it to an individual member of that group (in this case, Heidi Gilsing). This is a type of logical fallacy, which are common errors in reasoning that undermine the logic of an argument.

Key Points

Fallacy of composition:

• The Fallacy of Composition is the logical fallacy at work here.
• This fallacy occurs when one assumes that something true of part of a whole must also be true of the whole itself, or that a property of some or all individuals must also be a property of the group as a whole.
• In this instance, the argument incorrectly assumes that because 48 percent of the Swiss population is Protestant, then Heidi Gilsing, an individual Swiss person, must also be 48 percent Protestant, which doesn't make logical sense as an individual's religious affiliation is not a matter of percentages.

Additional Information

• Hasty Generalisation: This fallacy occurs when a conclusion is not logically justified by sufficient or unbiased evidence. It's often associated with generalizations made from small sample sizes or singular examples, but that's not the error in this argument.
• Ad Hominem: This is a fallacy where an argument is countered by attacking the character, motive, or other attribute of the person making the argument, rather than addressing the substance of the argument itself. It doesn't apply here since there's no character attack involved.
• Begging the Question: This is a fallacy where the conclusion of an argument is implicitly or explicitly assumed in one of the premises. This isn't the case in the presented argument, as the conclusion doesn't assume its own correctness.

In conclusion, the argument falls under the Fallacy of Composition, as it inaccurately applies a group statistic to an individual, demonstrating a common error in logical reasoning.

The correct answer is: A - III, B - IV, C - I, D - II

Important Points

Concept used:

a² + b² = (a - b)² + 2ab

Calculation:

Let's assume that the two numbers are A and B, ATQ, A × B = 21   … (i)  

Again, A² + B² = 58 

⇒ (A - B)² + 2AB = 58

⇒ (A - B)2 + 2 × 21 = 58   [ putting the value of AB from (i) ]

⇒ (A - B)2 = 16

⇒ (A - B) = √16

⇒ (A - B) = 4

∴ The difference between the two numbers is 4

The correct answer is Truancy

Important Points

• Truancy refers to the deliberate act of a student missing school or classes without permission from parents or the school.
• It's considered a serious issue as it can lead to various negative outcomes for the student, including academic underperformance and even legal trouble.
• Truancy is not limited to skipping school entirely but also includes staying away from specific classes or school-related activities.

Additional Information

• Truancy is a term used to describe any intentional unauthorized absence from compulsory schooling or educational activities.
• This behavior can be exhibited by students of any age from elementary school through high school.
• It is a serious issue as it can negatively impact the student's academic progress and overall personal development.
• Truant behavior can include being absent without permission from school, skipping classes (sometimes referred to as "class cutting") without a valid excuse, or consistently arriving late.
• It extends beyond just missing school, as it can also involve missing any school-related activities such as meetings, seminars, or any after-school programs.
• The reasons behind truancy can be complex and varied.
• It may be a response to school-related issues such as bullying, learning difficulties, lack of interest, or disengagement with the educational system.
• It can also stem from issues at home, including family problems, lack of parental supervision, or economic hardships.

The most appropriate answer is: Both Statement I and Statement II are incorrect.

Important Points

Statement I: In short-term memory, the sensory information is preserved and retained in the form and shape as it was originally received.

• This statement is incorrect. In short-term memory, sensory information undergoes a process of encoding and is stored in a more meaningful and organized way, rather than being retained exactly as it was originally received.
• Short-term memory involves the active processing and manipulation of information, and it has limited capacity and duration.

Statement II: In immediate memory, sensory information is subject to a process of encoding for being retained in the form of special visual and auditory impressions, symbols, signs, and words.

• This statement is also incorrect. Immediate memory, or sensory memory, is the very brief initial stage of memory where sensory information is held briefly for processing.
• It involves the initial perception and retention of sensory stimuli, but it is not subject to encoding in the form of specific visual and auditory impressions, symbols, signs, or words.

Therefore, both statements are incorrect as they do not accurately describe the characteristics and processes of short-term memory and immediate memory (sensory memory).

The correct answer is Vachaspatimista.

Important Points

The ancient Indian thinker who propounded five steps for the realization of the meaning of a religious truth (tattvakatha) that closely resembles the notion of learning in Dewey's theory of education is Vachaspati Mishra, also known as Vachaspati Mista.

Vachaspati Mishra was a prominent philosopher in the Advaita Vedanta tradition of Hindu philosophy. He is known for his work on explaining the teachings of Shankaracharya, the great exponent of Advaita Vedanta. One of his significant contributions is the "Bhamati" commentary on Shankaracharya's Brahmasutrabhasya (commentary on the Brahma Sutras).

In the Bhamati commentary, Vachaspati Mishra outlines five steps for the realization of the meaning of a scriptural or religious truth (tattvakatha), which closely resembles the notion of learning in Dewey's theory of education. These steps are:

• Sravana: Listening or hearing the teachings from a competent teacher or guru.
• Manana: Reflecting upon and contemplating the teachings to understand their implications and meanings.
• Nididhyasana: Deep meditation and constant contemplation on the truth to internalize and assimilate it fully.
• Dhyana: Sustained concentration and focus on the truth to experience its essence directly.
• Samadhi: The final stage where the seeker becomes one with the truth and attains complete realization

The statistical test that allows for the assessment of possible significance of difference across means of multiple groups is:

Analysis of Variance (ANOVA)

Important Points

ANOVA is a statistical technique that is used to compare the means of more than two groups to determine if there are significant differences between them.

• It does this by examining the amount of variation within each group and comparing it to the amount of variation between the groups.
• ANOVA is used when you want to compare the means of more than two groups.
• It's based on the principle of dividing the total variance of the data into variance within groups and variance between groups.
• The null hypothesis in ANOVA is that all group means are the same.
• If the variance between groups is significantly larger than the variance within groups, then we reject the null hypothesis and conclude that there is a significant difference between at least two of the groups.

Additional InformationStudent's t-test:

• This is a parametric test that's used when you want to compare the means of two groups to see if they're significantly different from each other.
• There are two forms of the t-test: independent (for comparing two separate groups of individuals) and dependent (for comparing two sets of measurements taken on the same group or individual).
• Paired t-test: This is a form of the Student's t-test that's used when you have two sets of measurements taken on the same group or individual and you want to see if the mean of the differences is significantly different from zero.
• The paired t-test is often used in pre-post study designs, where you're interested in whether there's a significant change after an intervention.

Chi-square test:

• This is a non-parametric test that's used to see if there's a significant association between two categorical variables.
• For example, you might use a Chi-square test to see if there's a significant association between gender (male vs. female) and pet ownership (own a pet vs. do not own a pet).

In your scenario, where you want to compare means across multiple groups, ANOVA is the appropriate test. However, it's important to remember that ANOVA assumes certain conditions are met, including that the data are normally distributed and that the variances of the groups being compared are approximately equal. If these conditions are not met, a non-parametric alternative like the Kruskal-Wallis test might be more appropriate.

The correct answer is A, C and E only

Important Points

A. Readiness and will power - This pertains to the learner's psychological state and motivation, not directly to the content.

B. Organisation of the contents or learning experiences - This is directly related to the content as it involves how the learning materials or experiences are structured and presented.

C. Basic potential of the learner - This is about the individual learner's capabilities and aptitudes, and it's not directly related to the content.

D. Nature of the contents or learning experiences - This is directly related to the content as it concerns the type or characteristics of the learning material or experiences.

E. Mastery over the subject matter - This refers to the learner's knowledge and understanding of the subject, which isn't directly about the content itself but about the learner's interaction with it.

Therefore, factors A, C, and E are not directly related to the content.

Calculation:

The price of 4 oranges is 7, then price of 1 orange is ₹7/4 (CP)

The price of 7 oranges is 13, then price of 1 orange is ₹13/7 (SP)

Let's assume that the number of oranges bought for ₹7/4 is k

Now, k × (13/7 - 7/4) = 30

⇒ k = (30 × 28)/3 

⇒ k = 280

∴ The correct answer is 280

The correct answer is 'A, B, C and E only.'

Key Points

• Let us explore the 5^th paragraph:
• " Rejecting/Neglecting/uninvolved parents (low warmth, low control) don't seem to care at all and can't be bothered with controlling, communicating or teaching their children."
• ​This sentence suggests that rejecting/neglecting/uninvolved parents (low warmth, low control) don't seem to care at all and can't be bothered with controlling, communicating, or teaching their children.
• Therefore, uninvolved parents do not show warmth towards their children, are non-communicative with their children, do not care for their children and do not bother about controlling their children.
• So, the most suitable answer is Option 2.​

The correct answer is 'Statement I is false but Statement II is true.'

Key Points 

• Let us explore 2^nd sentence in the first paragraph:
• "Her early work focused on a careful longitudinal study of 100 (mostly European American, middle class) preschool children.​"
• ​This sentence suggests that her early research was centred on a meticulous longitudinal study of 100 preschoolers, most of whom were middle-class European Americans.
• So, the statement I is incorrect.
• Let's have a look at the 2^nd sentence of the second paragraph:
• " They listen to concerns, give reasons for rules and allow more democratic decision making."
• This sentence suggests that Authoritative parents pay attention to complaints, provide justification for rules, and promote more democratic decision-making.
• So, the statement II is correct.
• Therefore, the correct answer is Option 4.​

The correct answer is 'Do not love their children.'

Key Points 

• Let us explore the third paragraph:
• "Authoritarian parents (low warmth, high control) seem cold and controlling in their interactions with their children. The children are expected to be mature and to do what the parent says, "Because I said so" There is not much talk about emotions. Punishments are strict, but not abusive. The parents love their children, but they are not openly affectionate."
• ​This sentence suggests that Authoritarian parents seem cold and inflexible in their interactions with their kids (low warmth, strong control).
• There isn't much discussion of feelings because kids are supposed to be responsible and to follow their parents' instructions "Because I said so."
• The penalties are severe but not cruel. Although they are deeply in love with them, the parents are not overtly affectionate.
• Therefore, Authoritarian parents in their interactions with their children are all of the following except do not love their children.
• Therefore, the correct answer is Option 4.​

The correct answer is 'Pre- school children​.'

Key Points

• Let us explore the second sentence of the first paragraph:
• "Her early work focused on a careful longitudinal study of 100 (mostly European American, middle class) preschool children."
• ​This sentence suggests that Baumrind's early work was centred on a meticulous longitudinal study of 100 preschoolers, the majority of whom were middle-class European Americans.
• Therefore, Baumrind's research study focused on pre-school children.
• So, the most suitable answer is Option 3.​

The correct answer is 'dissimilar parenting styles​.'

Key Points

• Let us explore the last paragraph:
• "Authoritarian, authoritative and permissive parents love their children and are trying to do their best; they simply have different ideas about the best ways to parent."
• ​This sentence suggests that parents who are authoritarian, authoritative and permissive love their kids and want to do the best they can; they just have different opinions on how to raise them.
• Therefore, authoritarian, authoritative and permissive parents have dissimilar parenting styles.
• So, the most suitable answer is Option 3.​
