UGC NET Paper 1: Held on 30th Sep 2022 Shift 1 (Previous Year Paper)

Given

The total number of children in 2016 = 7500

The total number of children in 2017 = 10500

The Percentage (%) of children who are not overweight in 2016 = (100 - 30) % = 70%

The Percentage (%) of children who are not overweight in 2017 = (100 - 28) % = 72%

Solution

The number of children who were not overweight in the year 2016:

⇒ 70% of 7500 = 5250 

The number of children who were not overweight in the year 2017:

⇒ 72% of 10500 = 7560

The total number of children who were not overweight in the year 2016 and 2017 together:

⇒ 5250 + 7560 = 12810

Given

The number of overweight women in 2018 = 25% 0f 30000

The number of overweight children in 2018 = 35% 0f 6000

The number of overweight men in 2018 = 30% 0f 31500 = 9450

Solution

The number of overweight women and overweight children together in the year 2018:

⇒ 25% 0f 30000 + 35% 0f 6000

⇒ 7500 + 2100 = 9600

The difference between the number of overweight women and overweight children together in the year 2018 and the number of overweight men in the same year:

⇒ 9600 - 9450 = 150

A food chain explains which organism in the ecosystem consumes another.

Key Points

Food Chain:

• The food chain is a succession of living things that transmit nutrients and energy from one organism to the next.
• Bioaccumulation is a process started when an organism absorbs a material more quickly than it is eliminated by catabolism and excretion.
• Pesticides are chemicals that can be used to kill fungi, bacteria, insects, plant diseases, etc.
• A substance from the carbamate family called carbaryl is mostly employed as an insecticide.
• Carbaryl is not anticipated to bioconcentrate appreciably.

Thus, Carbaryl pesticides would have the least chance of bioaccumulation in food chains. 

Hence, the correct answer is Carbaryl

Additional Information

• Bioaccumulation is the build-up of something in the body of an organism.
• In biology, bioaccumulation is typically associated with the build-up of damaging or harmful chemicals in a living thing. These chemicals will not break down in the body or are not able to be excreted. This will cause the chemical to accumulate over time.
• In India, pesticides must be registered with the Ministry of Agriculture & Farmers Welfare's affiliated Directorate of Plant Protection, Quarantine & Storage.

Given

The number of overweight women in 2019 = 30% of 27000

The number of overweight children in 2019 = 30% 0f 8000

The number of overweight men in 2019 = 16% 0f 33000 

Formula

Average = Total sum of all values/No. of all values

Solution

The average of the number of men, women and chlidren who were overweight in the year 2019

⇒ (8100 + 2400 + 5280)/3

⇒ 5260

Given

The number of overweight men in the year 2021 = 37.5% of 39000

The number of non-overweight men in the year 2021 = 62.5% of 39000

Formula

A % B = A/B × 100

Solution

⇒ (37.5% of 39000)/(62.5% of 39000) × 100

⇒ 60%

The number of overweight men in the year 2021 was 60% of the number of men who were not overweight in the same year.

Given

The number of overweight women in 2018 = 25% 0f 30000

The number of overweight men in 2020 = 12% 0f 35000 

Solution

The ratio of the number of overweight women in the year 2018 to the number of overweight men in the year 2020:

⇒ 7500 : 4200 = 25 : 14

Communication is a process of achieving a shift in understanding between two or more individuals. 

Key Points

• Interpersonal communication is conversations between people that take place face-to-face.
• Compatibility refers to having the ability to coexist peacefully with someone or something.
• Communication compatibility between individuals is rooted in empathy.
• Empathy involves two things: perception and communication.
• Communicating without the proper, correct perception of the meaning of the message, leads to a decrease in the empathic character of the relationship or conversation.
• Empathic communication requires embracing and tolerating different viewpoints and feelings in them as well as sharing them with them.

Thus, Communication compatibility between individuals is rooted in empathy. 

Hence ,the correct answer is Empathy

Additional Information

• An effective communication system has five essential components:  
• Speaker or sender.
• Transmission
• Form of the communication
• Recipient
• Desired

A question paper is a basic instrument used in a test or examination. 

Key Points

• It is typical for a teacher to put together questions for a test on the spot without taking into account the qualities of an effective test.
• The characteristic of a good question paper: 
• The question paper should have Validity which it is intended to measure.
• It must have Reliability to measure accuracy.
• It is written in precise, unambiguous language.
• The question paper should also be objective, practical, and candidate-friendly.

Thus, Subjectivity is NOT characteristic of a good question paper. 

Additional Information

• Evaluation is the methodical evaluation and explanation of the anticipated or actual effects of ideas or outcomes.

Bloom's taxonomy is used to categorised educational learning objectives into levels of complexity and specificity.

Key Points

Bloom's taxonomy:

• Bloom's taxonomy of learning Outcomes is divided into three parts: 
• Cognitive Domain
• Affective Domain
• Psychomotor Domain
• Bloom's taxonomy's greatest level of learning.
• The cognitive domain deals with the acquisition of knowledge and the growth of intellectual abilities.
• There are six major types of cognitive domains: Knowledge, Comprehension, Application, Analysis, Evaluation and Synthesis.
• The synthesis level is the highest level where learners try to categorize, combine, compile, compose, Create, devise, design, explain, and generate.

Thus, according to the revised Bloom's taxonomy Create is considered to be the highest for the learner. 

Additional Information

• The affective Domain has sub-major types: Reservice, Value, Organize, Respond and Characterization.
• Psychomotor Domain has five different levels Imitation, Manipulation, Precision, articulation, and Naturalization.

Hermeneutics is the study and application of interpretation, which entails a rationally supported understanding.

Key Points

Hermeneutics:

• It describes a theory of understanding as well as a corpus of historically varied strategies for interpreting texts, objects, and concepts.
• It deals with making the incomprehensible, understandable and communicative.
• The practice of interpretation particularly the interpretation of biblical texts, wisdom literature, and philosophical texts.
• Hermeneutics was initially used to interpret or exegete the Bible.

Thus, the term 'Hermeneutics' is drawn from theology. 

Additional Information 

• The history of hermeneutics spans eras, methodologies, and all of the humanities, social sciences, and even natural sciences disciplines.
• It has now been expanded to include concerns of general interpretation.

​A dynamic approach to learning is that the students are engaged and active participants in their education.

Key Points

• The best way to teach by doing this is to get actively involved in the activities.
• They must engage in activities that make them think, such as reading, writing, talking, and discussions.
• It must take an active role in many ways.
• Teachers place a strong emphasis on student participation in learning activities.
• Students to be actively involved in their learning, roleplaying, and simulations.

Thus, Dynamic approach to teaching means students should learn through activities.

Additional Information

• They must engage in activities that make them think, such reading, writing, talking, and discussions.
• This implies adopting an entirely new approach to a lesson so that they are not just waiting and listening but they must actively participate in various ways.

Historical research involves gathering and analyzing data on past events or ideas.

Key Points

Historical Research:

• In addition to assisting scholars in making links between past and present occurrences
• In order to understand how particular events affected the ones that followed, it investigates potential causes for those events.
• Some of the Limitations of Historical research are mentioned below: 
• The content analysis imposes restrictions.
• Prejudice in the analysis of historical materials.
• Sample representation cannot be guaranteed by researchers.
• A universal generalization of the class of facts
• Lack of ability to regulate outside factors

Thus, Historical research has the limitation of Universal generalization. 

Additional Information

• The primary sources used in historical research include documents from the time period being studied, including historical records, books, pictures, letters, and other documentary evidence.

MOOC is the most common method for providing online courses. 

Key PointsAssertion A: MOOCs on the SWAYAM portal can be used for earning upto 40% credits per semester by students.

• The Government of India launched the SWAYAM as MOOC.
• The UGC is regulator of SWAYAM regarding the credits.
• UGC Credit Framework laid down that university will assign the credits earned through SWAYAM an equivalent credit weight of up to 40%.

Thus, A is true. 

Reason R: All MOOCs on the SWAYAM portal are credit-based MOOCS.

• It is designed to achieve the three cardinal principles of Education Policy viz., access, equity and quality.
• The Courses on the SWAYAM divided Credit-based MOOCs and SWAYAM certificate.
• It also offers students certification courses after the completion of a small fee.

So, R is false. 

Therefore, A is true but R is false.

Hazards that are anthropogenic are those brought on by human behavior or inaction. 

Key Points

• Environmental hazards are described as extraordinary occurrences or chemicals in the Earth's ecological system that could have a negative impact on people and their valuable possessions.
• It can be further divided into two parts 
• Man-made hazards or Anthropogenic hazards
• Environmental hazards
• An environmental hazard is anything that has the potential to endanger the environment around it or have a negative impact on people's health.
• Anthropogenic hazards are certain negative conditions created with the participation of man, which affect the environment and public health.

The statistics of incidents due to human fault are as follows:

1. Emergency situations at nuclear power plants and plants - 45%;
2. Objects with increased risk (places of storage, transportation, manufacture, or use of substances that may cause an emergency) - 60%;
3. Plane crashes and maritime transport accidents - 80%; car accidents - 90%.

• This includes pollution and natural disasters like storms and earthquakes.
• For example, earthquakes, nuclear disasters, volcanic eruptions, landslides, floods, drought, subsidence, tropical storms, and wildfires.

Thus, the correct answer from the options is B, C, and E only. 

Important Points B. Nuclear Disaster: Nuclear disasters, such as those caused by accidents at nuclear power plants or improper handling of nuclear materials, are hazards that can occur due to human actions.

C. Floods: While floods can also occur naturally, human activities such as deforestation, improper land use, and urbanization can exacerbate flood risks and increase their frequency and severity.

E. Forest Fires: Forest fires can be caused by human activities such as campfires, arson, discarded cigarettes, or improper land management practices.

Additional Information

• Hazards caused by humans, other living things, biomes, and ecosystems could be detrimental.
• Environmental risks are frequently defined as the product of a hazard and the likelihood of its occurring.

The correct option is 9. 

Key Points

• The $symbol creates an absolute cell reference that won't change before the row and column coordinates. It can be written in different ways A1,$A$1,$A1, and A$1
• • sing symbolized Plus.
• So, $A$3 = 7

= $A$3 + B2 is equal to 9

= $A$3 + B2 = 7+2 = 9

As per the given information,

Certain number of birds are sitting on two trees A and B.

Let,

Number of birds on tree A = a

Number of birds on tree B = b

• Birds sitting on tree A, tell to the birds sitting on tree B, that if 2 birds from tree B shift to tree A, then we are equal in number.

→ (a + 2) = (b - 2)

→ a = b - 4   -----(i)

• However, the birds sitting on tree B, tell those sitting on A, that if two birds from your side (tree A) shift to our side (tree B), then we become double than you (tree A).

→ (b + 2) = 2(a - 2)

→ b + 2 = 2a - 4

→ b = 2a - 4 - 2

→ b = 2a - 6 ------(ii)

Putting the value of equation (i) in (ii) we get:

→ b = 2(b - 4) - 6

→ b = 2b - 8 - 6

→ b = 2b - 14

→ b = 14

now, putting b = 14 in equation (i) we get:

→ a = 14 - 4

→ a = 10

Thus, the number of birds on tree A = 10 and the number of birds on tree B = 10.

Hence, the correct answer is "10, 14".

The correct response is that Indian citizens who sign up for a Digilocker account get a dedicated cloud storage space that is limited to their Aadhar number.

Key Points 

This statement is incorrect. Digilocker allocates 1 GB of dedicated cloud storage space to every registered user, irrespective of whether their Aadhaar number is linked to their account or not.

Aadhaar plays a role in account creation: While an Aadhaar card is mandatory for signing up for a Digilocker account, it doesn't determine the storage space a user receives.

 Additional Information

It aims to eliminate the use of physical documents and provide access to digital documents anytime, anywhere, and share it online.

• This statement is correct. Digilocker is indeed designed to reduce reliance on physical documents by providing a platform for individuals to store their documents digitally.
• Users can access their digital documents anytime, anywhere with an internet connection, and they can also share these documents online securely. By digitizing documents and making them accessible electronically, Digilocker aims to streamline administrative processes, reduce paperwork, and enhance efficiency in accessing and sharing documents.

 

Citizens can self-upload documents and digitally sign them using the e-sign facility.

• This statement is also correct. Digilocker allows users to self-upload their documents digitally.
• Additionally, it provides the option for users to digitally sign their documents using the e-sign facility. The e-sign facility enables users to electronically sign documents using Aadhaar-based authentication, thereby providing a legally valid digital signature.
• This feature enhances the authenticity and validity of digitally signed documents stored in Digilocker, making them suitable for various official and legal purposes.

 

The slogan of Digilocker is "My documents, Anytime, Anywhere."

• This statement is also correct. "My documents, Anytime, Anywhere" is indeed the slogan of Digilocker.
• This slogan encapsulates the core objective of Digilocker, which is to provide users with convenient access to their digital documents from anywhere and at any time.
• It emphasizes the platform's aim to offer users flexibility and convenience in managing and accessing their documents digitally, without being constrained by physical or geographical limitations.

Sustainable development is a development that meets the existing demands without risking the capacity of future generations to satisfy their own needs.

Key PointsStatement I: An ethical framework of sustainable development provides normative guidance regarding our relationship with the environment.

• ​An ethical framework for sustainable development offers normative direction.
• The model presented below illustrates the relationship between natural wealth and human happiness.
• Protect, restore, and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, halt and reverse land degradation, and halt biodiversity loss
• It is well-being in a hierarchy of human institutions, including technology, economy, politics, and ethics.

Thus, Statement I is true. 

Statement II: Anthropocentric model is misleading as evident from its environmental consequences.

• The environmental effects of the anthropocentric approach have made it clear that it is a deceptive and harmful framework.
• The sustainability hypothesis is based on the idea that both natural and human-made evolution have intrinsic worth.
• Anthropocentric models are misleading as evident from their environmental consequences.

So, Statement II is true. 

Therefore, Both Statement I and Statement II are true.

A logical fallacy is a mistake in reasoning that reduces the strength and persuasiveness of an argument.

Key Points

• There are two main types of fallacies: Formal fallacy and informal fallacy.
• An informal fallacy is an error in the argument's form, content, or context.
• ​The false cause is a fallacy when an argument makes the incorrect claim that one condition of affairs causes another state of affairs to occur.
• The error is drawing a conclusion based on a purported causal relationship that is either not true.
• In the above argument, the claim "Sun shines when there is light anyway" is a factual wrong claim. This is one of the reasons for the convenience that we should value the moon.

Thus, the Fallacy of False Cause is committed in this argument. 

Additional Information

• False Dilemma is an informal fallacy based on a presumption that incorrectly restricts the options that are accessible.
• The fallacy of equivocation is a formal fallacy that happens when a crucial term or phrase is employed in an unclear manner
• Appeal to Emotion is the manipulation of the recipient's emotions in order to win an argument in the absence of factual evidence.

Given

The container gets completely filled with bacteria = 30 minutes

Concept

Every 1 minute = Number of bacteria in a container doubles

Solution

No. of bacteria intially in the cup =1

After 1 min no. of cells will be 2×1=2¹

After 2 min = 2×2 = 2²

After 3 min = 2×2×2 = 2³

So, after 30 min no. of cells will be 2³⁰

Quantity of whole cup = 230 cells

Quantity of 1/4th a cup = 230/2² = 2²⁸

Thus, time taken to fill half of the cup = 28 min

Hence, it will be 1/4th in 28 minutes.

Shortcut Trick

By using the Method of Alligation:

Ratio of (Original Students) : (New Boys) = (14.5 − 12.5) : (15 − 14.5)

⇒ Ratio = 2.0 : 0.5 = 4 : 1

Since the number of new boys is 5 (which corresponds to 1 part),

Original number of students (4 parts) = 4 × 5 = 20.

∴ The correct answer is 20 students.

Alternate Method

Given:

Average age of original students = 15 years

Number of new boys = 5

Average age of new boys = 12 years 6 months = 12.5 years

New average age = 15 years − 6 months = 14.5 years

Original (n)

New Boys (5)

15 12.5

14.5

2.0 0.5

Ratio = 4 : 1

Original students = 4 × 5 = 20

Formula Used:

Total Sum = Average × Number of Observations

Calculation:

Let the original number of students in the class be n.

⇒ Total age of original students = 15 × n = 15n

⇒ Total age of 5 new boys = 5 × 12.5 = 62.5 years

⇒ Total number of students after admission = n + 5

⇒ New total age of the class = 14.5 × (n + 5)

According to the given condition:

⇒ 15n + 62.5 = 14.5 × (n + 5)

⇒ 15n + 62.5 = 14.5n + 72.5

⇒ 15n − 14.5n = 72.5 − 62.5

⇒ 0.5n = 10

⇒ n = 10 ÷ 0.5 = 20

∴ The correct answer is 20 students.

Additional Information

Weighted Average

For two distinct groups with sizes n₁ and n₂ and averages A₁ and A₂ respectively, the combined overall average is calculated using the formula: (n₁A₁ + n₂A₂) ÷ (n₁ + n₂).

Method of Alligation

It is a shortcut method primarily used to determine the exact ratio in which two quantities or sets are mixed to achieve a desired combined average. The ratio is derived directly by cross-subtracting the combined average from each individual average.

Replacement in Averages

When an existing observation is substituted by a new one, the direct relation between the values is: New Value = Replaced Value + (Total Number of Observations × Net Change in Average).

Key Points

Assertion A: Most cyclones cause widespread damage in coastal areas.

• Cyclones are a phenomenon that happens due to a low-pressure area surrounded by swift inward air circulation.
• There are two types of cyclones: Tropical cyclones and Extra-Tropical cyclones.
• Coastal areas are more susceptible to destruction from tropical cyclones.

Thus, Assertion is correct but R is not correct

Reason R: Energy of most cyclones increases after landfall.

• Tropical cyclones originated in the region between the Tropics of Capricorn and Cancer.
• Extratropical cyclones are known to originate in polar regions, but they also occur in temperate zones and high-latitude regions.
• Tropical cyclones usually lose strength quickly over land because they are cut off from their main supply of energy.

So, Reason  is not correct. 

Therefore, A is correct but R is not correct.

Approaches are frameworks to study phenomena. 

Key Points

Therefore, A-IV, B - I, C - II, D - III is correct matching.

Malware is any programme that purposefully attacks a computer, network, or server. 

Key Points

Malware **:**​

• Malware is able to infect networks and devices and is designed with the intention of negatively affecting such devices, networks, and/or their users.
• Examples of Malware are Computer viruses, worms, Trojan horse ransomware, and spyware.
• These harmful applications steal, encrypt, and erase private information.
• They also change or hijack fundamental computer operations and track end users' online behaviours.

Thus, Worms and Viruses are two examples of malware. 

Additional Information

• Malware can have terrible effects in some situations while having very minor and innocuous ones in others.
• This harm may manifest itself to the user or endpoint in many ways depending on the type of malware and its objective.

Visual communication allows for real-time voice and video material transfer between two or more people. 

Key Points

VIdeo-conferencing system:

• There are two types of video conferencing that have emerged: point-to-point conferencing and multipoint conferencing.
• The essential component required for a video-conferencing system are: 
• Desktop or laptop computer
• Web camera
• Microphone
• Speakers or Headphones
• High-speed internet access
• Account with a video conferencing service.

Thus, the Telephone is not an essential component required for the video-conferencing system. 

Additional Information

• VoIP technology is mainly used in video conferencing software to transport audio and video signals.

Data collection is the act of acquiring and measuring information.

Key PointsStatement I: The qualitative data are powerful because they are collected from very sensitive social, historical and temporal context.

• Qualitative data is descriptive and conceptual information gathered through surveys, interviews, or observation.
• It is collected from text, audio and images and shared through data visualization tools.
• These data are very sensitive in a social, historical and temporal context.

Thus, Statement I is true. 

Statement II: Context sensitivity cannot be completely removed from the qualitative data.

• The context-sensitivity of data-gathering processes, and the method's alignment with the application context.
• Context-sensitive research puts findings in a social, historical, and temporal context.
• It cannot be completely removed from qualitative data.

So, Statement II is true. 

Therefore, Both Statement I and Statement ll are true.

A fallacy is known as Hetvabhasa in Indian logic. 

Key Points

• A fallacy occurs when the middle term appears to be the reason but it is not a valid reason.
• According to Nyaya School, there are five different types of fallacies considered to be material fallacies.
• The Nyaya syllogism recognizes the fact that verbal form is not the essence of inference and is required only to convince others.
• Material fallacies occur when the reasoning is unsound because of an error concerning the subject matter of the argument.

Thus, the correct answer from the options are A, B and D only. 

Additional Information

• They address errors in the formulation of arguments, the content of expressions, etc.
• Presumption fallacies are another name for material fallacies.

According to the given information:

The codes in tabular form :

Thus, the code for 'leaves' is '7'.

Hence, the correct answer is "7".

Indian philosophical and epistemological traditions served as the sole foundation for the development of ancient Indian education. 

Key Points

• The ancient Indian educational system was created to meet both individual and societal demands, making its development natural.
• The enduring and unending sources of Indian civilization and culture were the ancient educational institutions.

Thus, some of the most notable universities that evolved during the ancient period in India were situated at Takshashila, Vikramshila, Jagaddala, Odantapuri and Nalanda. 

Additional Information

• There were three different sorts of institutions at that time Gurukulas, Parishads (Academies), and Sammelans (Conferences).

Nyaya philosophy is a system of logical realism. 

Key PointsAssertion A: According to classical Indian Logicians (Naiyayikas), all fallacies are material fallacies.

• The fallacy is known as Hetvabhasa in Indian logic.
• According to Nyaya School, there are five different types of fallacies considered to be material fallacies.
• Material fallacies occur when the reasoning is flawed due to a mistake about the topic under discussion.

So, Assertion is true

Reason R: According to Nyaya, Syllogism is deductive-inductive and formal-material.

• The Nyaya syllogism is formal-material and deductive-inductive.
• The Nyaya syllogism acknowledges that verbal form is simply necessary to assure others.
• It does not constitute the substance of a conclusion.

Thus, Reason is true. 

Therefore, Both A and R are true and R is the correct explanation of A.

A logical fallacy is a mistake in reasoning that reduces the strength and persuasiveness of your argument.

Key Points

• There are two main types of fallacies: Formal fallacy and informal fallacy.
• An informal fallacy is an error in the form, content, or context of the argument.
• Ignoratio elenchi also known as the irrelevant conclusion, is an informal fallacy.
• Irrelevant conclusion in which an argument may or may not be logically acceptable and sound but fails to address the subject in question.
• The above argument removes the hunger for knowledge we have to find solutions but the arguer draws the conclusion "one should stick to the food" is not a logical conclusion at all.

Thus, the Ignoratio elenchi (irrelevant conclusion) fallacy is committed in this argument. 

Additional Information

• False Dilemma is an informal fallacy based on a presumption that incorrectly restricts the options that are accessible.
• Begging the Question is an error in logic where the premises of an argument are predicated on the validity of the conclusion.
• Appeal to Emotion is the manipulation of the recipient's emotions in order to win an argument in the absence of factual evidence.

Validity refers to test measures which we are supposed to measure. 

Key Points

• Validity in research basically indicates the accuracy of methods to measure something. If specific devices or tools measure accurate things and outcomes are closely related to real values then it is considered being as valid.
• It means that they accurately reflect the genuine features, traits, and variations in the physical or social reality.
• On the basis of cause-and-effect relationships, the Validity is divided into Internal validity and External validity.
• Internal Validity is the level of assurance that the causal relationship under test is reliable and unaffected by other variables or factors.
• There are eight threats to internal validity in research: history, maturation, instrumentation, testing**, s**election bias, regression to the mean, social interaction and attrition.
• A method is probably invalid if it is not trustworthy.

Thus, Maturation, History and Instrumentation are threats to internal validity in research.

Additional Information

• External validity is the degree to which research findings can be generalised to different contexts, populations, or events.

Communication is transferring information or messages from one person or group to another. 

Key Points

Grapevine communication:

• Grapevine communication is informal communication that takes place within an organization without adhering to a recommended framework.
