UGC NET Paper 1: Held on 25th Dec 2021 Shift 2 (Previous Year Paper)

Formula Used:

Speed = Distance/ Time

Calculation:

Statement I:-

Total distance = Length of the train + Length of the platform

Total distance = 60 m + 90 m = 150 m

Time = 10 seconds

Speed = 150/10 = 15 m/sec.

⇒ 15 × \(\frac{3600}{1000}\) = 54 km/hr.

The given statement is incorrect.

Statement II:

If the distance is same, then the ratio of the speed is a : b and the ratio of the time is b ∶ a.

The given statement is incorrect. 

The correct option is 1 i.e.Both Statement I and Statement II are false.

Competent communicators entail the ability to communicate effectively and appropriately, as well as ability to apply and adapt such information to a variety of communication situations. 

Key Points

• Educational policymakers and advocates have emphasised a back to basics mindset, communication competency has become a focus in higher education.
• The traits of competent communicators have been broken down into five areas:
• ​Self-awareness: Being conscious of your own communication behaviours is what self-awareness entails. Self-monitoring is a part of this which means you watch your own communication behaviours and make sure they're acceptable for the context.
• Adaptability: The ability to modify your communication to the environment you're in is referred to as adaptability.
• Empathy: Empathy is the ability to communicate with another person while imagining yourself in their shoes.
• Cognitive complexity: The concept of cognitive complexity refers to the idea that a person's communication behaviour can be influenced by a variety of factors.
• Ethics: To communicate in a morally correct manner is to practise ethics.

Therefore, B, C and E options are the correct answer. 

Additional Information

• Competent communicators can judge what would be suitable and effective in a given situation and adjust their conduct accordingly.
• A skilled communicator recognises that there is no one-size-fits-all approach to communication and that it must be tailored to the context and recipient.
• A good communicator invests time in learning communication skills that will allow him or her to communicate effectively in a variety of scenarios.

Private university means a university duly established through an Act by a sponsoring body viz. a Society registered under the Societies Registration Act 1860.

Key Points

• It comes under the law for the time being in force in a State or a Public Trust or a Company registered under Section 25 of the Companies Act, 1956.
• The private university shall be established by a separate State Act and shall conform to the relevant provisions of the UGC Act, 1956.
• A private university is a unitary university having adequate facilities for teaching, research, examination and extension services.
• BITS Pilani (Birla Institute of Technology and Science) is a private deemed to be a university in Pilani, India.
• It largely focuses on engineering and scientific higher education and research.
• It established five campuses and 15 academic departments, it has become the first internationally recognised deemed university after expanding to campus in Dubai.

Therefore, BITS Pilani is a private deemed to be University. 

Additional Information

• Anna University was formed as a state-run public university as a unitary university on September 4, 1978.
• It provides higher education in Engineering, Technology, Architecture, and Applied Sciences that is relevant to society's current and future demands.
• Burdwan University is a public university in Purba Bardhaman, West Bengal, India.

Nyaya (Sanskrit: "Rule" or "Method") is one of India's six philosophical schools (darshans), known for its logic and epistemological analyses. 

Key Points

• The Nyaya system makes a significant contribution by explaining in great detail the means of knowledge known as inference(anumana).
• Anumana literally means "after knowledge," as in "knowledge that comes after other knowledge."
• The first is the pratijna, which is a logical statement that must be proven.
• The second is hetu, which expresses the cause for the proposition's formation.
• The third is udaharana, which refers to universal concordance and example.
• The fourth is upanaya, which is the application of universal concordance to the current situation.
• The fifth proposition is nigamana, which is a conclusion derived from the prior propositions. The Avayavas are the five members of the Indian syllogism.​

​Therefore, Pratijna, Hetu, Udaharaṇa, Upanaya, Nigamana is the Correct sequence. 

Additional Information

• This can be explained using a classic inference example: the effect of fire on the perception of smoke. When one observes smoke on a far hill, one recalls the universal concomitance (Vyapti) between smoke and fire and concludes that there is fire on the distant hill.
• A typical Nyaya syllogism is as follows.

1. There is fire (pratijna) on this hill;
2. There is smoke on this hill (hetu),
3. Anything that produces smoke, such as an oven, is on fire (udaharana),
4. Because this hill has smoke, which is inextricably linked to fire (upanaya),
5. this hill has fire (nigamana).

The answer is B and D.

Key Points

• Let's refer to the passage:
• Use of artificial lights at night gives us more working and studying hours but it results in the problem of 'loss of night.'
• We find it difficult to fall asleep when the glow of streets enters our homes.
• It impacts our sleep-wake rhythm, which could have serious implications for our moods and health.
• From the above-mentioned statements, it is evident that excessive hours of artificial light adversely impact our 'sleep cycle' and 'moods and health'.

Thus, the correct answer is B and D.

Additional Information

• Adversely means in a bad or harmful manner.
• For eg: The unpredictable weather conditions are adversely affecting our farmer community.

The correct answer is illuminated advertising.

Key Points 

• Let's refer to the passage:
• Light pollution refers to the harmful impact of artificial outdoor lighting.
• While artificial outdoor lighting is needed in the form of street lights it increases safety on roads and enables us to study and work in the dark, its use for flood lighting, illumination, advertising, etc., has grown manifold in recent decades, resulting in the problem of light pollution.
• ​From the above-mentioned statements, it is evident that one of the major pollutants is in the form of illuminated advertising.

​Thus, option 2 is the correct answer.

Additional Information

• Here, Illumination means decorative lighting.
• For eg: The houses in New Hampshire are illuminated prior to Christmas.

The correct answer is the altered activities of nocturnal creatures.

Key Points

• Let's refer to the passage:
• Use of artificial lights at night gives us more working and studying hours but it results in the problem of 'loss of night.'
• Illumination of gardens impacts animals and insects too.
• It is nocturnal insects and birds that suffer the most due to light pollution.
• It makes them disoriented, impacts their reproduction and thus their populations.
• From the above-mentioned statements, it is evident that the 'loss of night' will lead to the altered activities of nocturnal creatures.

​Thus***,*** option 1 is the correct answer.

Confusion Points

• In the passage, it is mentioned that 'use of artificial lights at night gives us more working and studying hours but it results in the problem of 'loss of night.'
• Here increased working and studying hours don't equate to productivity.
• Therefore, options 1, 2 and 4 are not correct.

Additional Information

• Nocturnal means things relating to or occurring at night.
• Nocturnal animals are animals that are active at night**.**

​

The correct answer is Outdoor artificial light.

Key Points

• Let's refer to the passage:
• A global light pollution map developed by a group of researchers has ranked New Delhi, Kolkotta ( Kolkata) and Bengaluru as the three cities with the highest light pollution in India.
• Light pollution refers to the harmful impact of artificial outdoor lighting.
• ​From the above-mentioned statements, it is clear that the light pollution map is related to the adverse effects of outdoor artificial light.

Thus, option 1 is the correct answer.                                        

Additional Information

• Adverse means harmful or unfavorable.
• For eg: The adverse health impacts of fried foods are alarming.

The correct answer is Increased outdoor brightness during night time.

Key Points

• ​Let's refer to the passage:
• Light pollution refers to the harmful impact of artificial outdoor lighting.
• Studies show that the brightness from outdoor lights has risen steadily across India over a 20year period, with New Delhi, Telangana, Maharashtra, Karnataka and Uttar Pradesh showing a "very high light intensity pollution" rise between1993 and 2013.
• Use of artificial lights at night gives us more working and studying hours but it results in the problem of 'loss of night'.
• From the above-mentioned statements, it is evident that light pollution intensity refers to increased outdoor brightness during night time.​

Therefore, option 1 is the correct answer.

Additional Information

• Intensity means extreme energy, strength, force, etc.
• The intense exam preparation has made him confident.

Important Points

Therefore, the correct answer is A - III, B - I, C - II, D - IV

Key Points

Hetvabhasa can be explained as-

• Hetvabhasa is a Sanskrit term which means fallacy in the English language.
• In other words, in Indian logic, a fallacy is called Hetvabhasa.
• A fallacy occurs when the middle term appears to be the reason but it is not a valid reason.
• There are five kinds of fallacies according to Nyaya school.
• All the five fallacies are regarded as material fallacies.
• Material fallacies occur when the reasoning is unsound because of an error concerning the subject matter of the argument.
• Material fallacies are also known as fallacies of presumption.
• They are informal fallacies.

Important Points

• Ashraya Siddha

When the minor term used in the argument is not real. So, the minor term is the locus of the middle term but when the minor term is unreal, the middle term cannot be present in it. For example; sky-lotus is fragrant, because it is a lotus, like the lotus of the pond.

• Svarupasiddha

It occurs when the minor term is not unreal but because of the very nature of the middle term, the middle term cannot be present in the minor term. For example; the sound is a quality because it can be seen. Here the sound is the minor term, it is real but the middle term seen cannot be present in the minor term sound because sound cannot be seen, it can be heard.

• Viruddha

It occurs when we have contradicted the middle term. For example, the sound is eternal, because it is produced. Instead of proving the major term, the middle term proves the opposite.

• Badhita

It is a Hetvabhasa that occurs when the middle term is contradicted by some other pramana, other than inference, like, perception. One instance of the Badhita fallacy is fire is cold, because it is a substance. Here fire is cold is a fallacy, because the middle term is not compatible with the minor term.

Therefore, the correct answer is Viruddha.

A tablet computer is a computer that lies in between a laptop and a smartphone in terms of size. 

Key Points

Statement I: - Tablet computers have touch screens.

• A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package.
• Capacitive touch screen technology is the style we interact with most. This is the kind of display we see on our smartphones, laptops, and tablet screens.
• The touchscreen display is operated by gestures executed by finger or digital pen (stylus), instead of the mouse, touchpad, and keyboard of larger computers.

​So, Statement I is true

Statement II: - A tablet computer has a keyboard.

• A slate-like model built to withstand rigorous handling and harsh environments.
• Instead of using a mouse, touchpad, or keyboard, the touchscreen display is controlled by movements made with a finger or a digital pen (stylus).
• The existence and look of physical keyboards can be used to classify portable computers.
• Tablets also come with a hybrid design, also known as a convertible or hybrid notebook which is similar to a standard notebook but features a removable display that may be used as a slate.

​Thus, Statement II is false

Statement I is true but Statement II is false​.

Additional Information

• Alan Kay, a PhD student at the University of Utah, championed his idea of a small, powerful tablet-style computer.​
• Cambridge Research's Z88 and Linus Technologies in 1987 launched their first real tablet computers.

Important Points

• To draw the graph to the right, we have used the power calculator on the previous page, and the power curve from the default example 600 kW wind turbine.
• We have used a standard atmosphere with an air density of 1.225 kg/m³.
• For each of the Weibull parameters 1.5, 2.0, and 2.5 we have calculated the annual energy output for different average wind speeds at turbine hub height.
• As you can see, the output may vary up to 50 percent depending on the shape parameter at a low average wind speed of 4.5 m/s, while it may vary some 30 percent at a very high average wind speed of 10 m/s at hub height.

Hence, the power output from an ideal windmill will increase by a factor of about ~2 if the wind speeds increase from 4.0 m/s to 5.0 m/s.

3529, 64, 9817, 115, 3257, ?

Here a specific pattern follows as

3529 = 5 + 9 = 14  ⇒ 4 &  3 + 2 + 1  = 6  

So, the number becomes 64 

Similarly, 9817 = 8 + 7 = 15 ⇒ 5 & 9 + 1 + 1 = 11 

So, the number becomes 115

3257 = 2 + 7 = 9 & 3 + 5  = 8

So, the number becomes 89

The correct answer is 89 here.

Key Points

  A media kit is a collection of information put together by a firm to give reporters with basic information about itself. The media kit is a promotional public relations tool that can be used for a variety of purposes, including promoting the launch of a new company, promoting the launch of a new product or service by an existing company, giving a company a way to present itself as it wishes to be seen, and/or saving time by eliminating the need for employees to answer the same questions over and over again.

Important Points In order to spread the message or tell people about the brand or mission, one has to use different forms of communication. When communication occurs between the brand and an external audience—customers, clients—it’s known as external communication.

Examples of External Communication are-

1. Media Kits
2. Client Pitches and Presentation
3. Email Marketing
4. Official blogs
5. Social Media

Additional InformationClassroom Communication- There are three types of classroom communication: verbal, nonverbal, and written. Anything a teacher or student says out loud is referred to as verbal communication. People's body language is referred to as nonverbal communication. Written communication, such as report card remarks or student tasks, is writing intended for a specified audience. Teachers and students communicate with one another in a variety of ways, using all three styles of communication.

Internal Communication- Internal communication implies communication that takes place between the members of the organization.

Confidential communication- Confidential communication involves statements (oral, written, or nonverbal) made in confidence between two people who have trust in each other and believe that the communication will be kept in confidence.

Therefore, the correct answer is External communication.

Important Points

The main component of decision traps to illustrate are the possible evaluatory framework to monitor the learning process are-

Overconfidence bias- occurs when what you choose to believe is more important than the truth. Overconfidence bias occurs when you start to rely on your own judgments and beliefs about things rather than reality.

The overconfidence bias is one of the most powerful and widespread cognitive biases known to science. It has a tremendous impact on decision-making because our behaviours are determined by how we think about things.

**Frame blindness-**The concept of framing bias relates to the idea that the way data is presented can influence how people make decisions.

The framing effect is a cognitive bias in which people choose options based on whether they have positive or negative implications, such as a loss or a gain. When provided with a negative frame, people tend to shun danger, but when offered with a positive frame, they seek risks.

Taking shortcuts- A heuristic is a mental shortcut that helps people solve issues and make decisions more quickly. These rule-of-thumb tactics reduce decision-making time and enable people to perform without continually pausing to consider their next move.

Heuristics, on the other hand, have both advantages and disadvantages. While heuristics can be useful in a variety of contexts, they can also cause cognitive biases. Understanding how heuristics function and the biases they can bring can help you make better and more accurate decisions.

Therefore,  the correct answer is A, C and D only.

Important Points

 Feedforward is the provision of the context of what one wants to communicate prior to that communication. In purposeful activity, feedforward creates an expectation that the sender anticipates. When an expected experience occurs, this provides confirmatory feedback. The concept of feedforward was developed by business educator and coach, Marshall Goldsmith. Feedforward is the reverse exercise of feedback. It’s the process of replacing positive or negative feedback with future-oriented solutions. In simple terms, it means focusing on the future instead of the past

Additional Information Introduction is defined as a written or spoken at the begining of a speech or a written material.

Key Points

Biomass is organic material that is renewable and comes from plants and animals. Many developed countries are boosting their use of biomass fuels for transportation and electricity generation as a way to reduce carbon dioxide emissions from fossil fuel consumption. Biomass contains stored chemical energy from the sun. Photosynthesis is the process by which plants make biomass. Biomass can be burned directly for heat or processed into renewable liquid and gaseous fuels using a variety of techniques.

Important PointsBiomass has always been an important energy source for the country considering its benefits.  It is renewable, widely available, carbon-neutral, and can provide significant employment in rural areas.  Biomass is also capable of providing firm energy.  About 32% of the total primary energy use in the country is still derived from biomass and more than 70% of the country’s population depends upon it for its energy needs.  

Additional Information Biomass sources for energy include:

• Wood and wood processing wastes—firewood, wood pellets, and wood chips, lumber and furniture mill sawdust and waste, and black liquor from pulp and paper mills.
• Agricultural crops and waste materials—corn, soybeans, sugar cane, switchgrass, woody plants, and algae, and crop and food processing residues.
• Biogenic materials in municipal solid waste—paper, cotton, and wool products, and food, yard, and wood wastes.
• Animal manure and human sewage.

Therefore, the correct answer is 32%.

Key Points

• This international convention aims to put the United Nations Framework Convention on Climate Change of reducing greenhouse gas concentrations in the atmosphere to counteract global warming into practice.
• It was adopted in December 1997 in Kyoto, Japan which has been in effect since 2005, required 41 nations and the European Union to reduce greenhouse gas during the "commitment period" of 2008–12.
• Total 192 member states ratified the convention, Canada had withdrawn from the protocol in December 2012.
• Participants in the Kyoto Protocol convened in Doha, Qatar in December 2012, after the first commitment period of the Protocol had finished, to adopt an addendum to the original Kyoto agreement.
• This was known as the Doha Amendment, which added new emission-reduction targets for these countries for the second commitment period, 2012–2020.
• All UNFCCC parties ratified another deal, the Paris Climate Agreement, in 2015 at the Sustainable Development Summit in Paris, thus replacing the Kyoto Protocol.

​Therefore, In 2012, did the first commitment period of the Kyoto Protocol come to an end.

Additional Information

• The following important greenhouse gases are addressed:
• Carbon dioxide (CO2)
• Methane (CH4)
• Nitrous oxide (NOx)
• Hydrofluorocarbons (HFCs)
• Perfluorocarbons  (PFCs)
• Sulphur Hexafluoride (SF6)
• Participating countries agreed to reduce their emissions by an average of 5% below 1990 levels throughout the Protocol's first period (2008-12).

Nonverbal communication is the process of transmitting meaning without the use of written or spoken words.

Key Points

• Nonverbal communication aids in the establishment and maintenance of interpersonal relationships whereas verbal communication merely aids in the communication of external events.
• Nonverbal communication is a method of conveying information through behaviour without using words.
• It includes facial expressions, the tone and pitch of the voice, gestures displayed through body language (kinesics) and the physical distance between the communicators (proxemics).
• Nonverbal communication is important in our lives because it improves a person's capacity to relate, participate, and form meaningful interactions in daily life. People may create deeper relationships with others if they have a better knowledge of this form of communication.
• There are no such official guides that govern our use of nonverbal communication.

Therefore, A, B and C is the correct option. 

Additional Information

• The difference between Nonverbal communication and Verbal Communication is based on principles are following:
• nonverbal communication typically conveys more meaning than verbal communication,
• nonverbal communication is more involuntary than verbal communication,
• nonverbal communication is frequently more ambiguous than verbal communication,
• nonverbal communication is frequently more credible than verbal communication.
• Nonverbal communication serves a number of purposes.
• Nonverbal communication influences verbal communication by complementing, reiterating, substituting, or contradicting verbal messages.
• It has the ability to influence people because it is a crucial component of deception and can be used to assert authority or win cooperation.

Choice Based Credit System, which provides students with an effective learning platform by widening their educational horizons. 

Key Points

• It is a student-centred course in which students select their own subjects.
• The CBCS method employs credits instead of the traditional marking system.
• CBCS system Offers Three Types Of Courses to students: Core, Elective, and Foundation.
• Core Course: In order to fulfil the credit requirement, students must choose a core subject.
• Elective Courses: These studies cover a broader range of topics and are designed to improve students' abilities.
• The foundation courses include Ability Enhancement Compulsory Courses (AECC) and Skill Enhancement Courses (SEC).
• AECC courses are environmental Science and English communication that is centred on content that leads to knowledge growth.
• SEC courses are value and skill-based with the goal of offering hands-on training, competencies, and skills, among other things.

​Therefore, In CBCS, Ability Enhancement Courses are of two kinds Ability Enhancement Compulsory Courses and Skill Enhancement Courses.

There is a massive dip in international students coming to India for higher education studies between January and December 2021 compared to 2019.  

Key Points

• Recognising the relevance of internationalisation and student inflow in India, the Association of Indian Universities has been conducting an annual survey of international students in an Indian educational institution.
• According to report, the Internationalisation of Higher Education in India identified several issues which are following: 
• ​Locational Disadvantages
• ​Regulatory restrictions and lack of support from regulatory bodies
• Lack of enough applications from international students
• Difficulties in Obtaining Visa for Foreign Students
• Lack of residential accommodation for international students
• Lack of quality facilities and infrastructure
• Lack of enthusiasm amongst the faculty about international students
• Lack of enthusiasm amongst the students of the university about international students
• Medium of Instructions
• Difficulties in recognition of international qualification

Therefore, A and B is the correct statement. 

Additional Information

• To increase international students In higher education the Government of India various steps which are mentioned below: 
• The government urged the various universities to build world-class hostels for overseas students.
• The Champion Services Sector Scheme has a provision for financial help to specific institutions where international students take admission.
• University that accepts overseas students must establish the International Students' Office to serve as a one-stop-shop for all of the international students' needs, beginning with their acceptance to the university.
• Twinning, Joint, and Dual degrees with credit transfer mechanisms are also being considered by the Ministry as ways to improve academic interactions between Indian and overseas institutions.
• All institutions have been asked to activate their alumni networks and leverage this network to attract more students to Indian universities.

Qualitative research is defined as research that uses methodologies like participant observation or case studies to produce a narrative and descriptive account. 

Key Points Statement I: Qualitative research is impressionistic and subjective.

• Qualitative research at this level entails an interpretive, naturalistic approach to the world.
• Qualitative Research is impressionistic rather than definitive.
• It aims to understand or interpret events through the lenses of the meanings individuals assign to them.
• Qualitative research is essentially subjective in nature, as it aims to comprehend human behaviour and the factors that influence it.

So, the statement I is correct. 

Statement II: Quantitative research has a higher level of possibility of generalising the findings.

• Quantitative research is described as a systematic analysis of phenomena through the collection of measurable data and the application of statistical, mathematical, or computational methods.
• Quantitative research is the process of collecting and interpreting numerical data.
• It can be used to look for patterns and averages, make predictions, test causal linkages, and generalize results to wider populations.
• In the natural and social sciences, such as biology, chemistry, psychology, economics, sociology, and marketing, quantitative research is widely used.

Therefore, statement II is correct. 

Hence, Both Statement I and Statement II are true.

Given:

Total employees = 35000

Calculation:    

Number of employees in organization D = 15% of 35000 

⇒ Number of employees in organization D = 5250

Number of females in organization D = 5250 × \(\frac{3}{3 + 2}\)

⇒ Number of females in organisation D = 3150

Number of employees in organization E = 14% of 35000  

⇒ Number of employees in organization E = 4900

Number of males in organization E = 4900 × \(\frac{1}{3 + 1}\)

⇒ Number of males in organisation E = 1225

Sum = 1225 + 3150 = 4375

∴ The sum total of the number of females in Organisation D and the number of males in Organisation E is 4375

The correct option is 1 i.e. 4375

Given:

Total employees = 35000

Calculation:    

Number of employees in organization A = 18% of 35000 

⇒ Number of employees in organization A = 6300

Number of males in organization A = 6300 × \(\frac{3}{3 + 7}\)

⇒ Number of males in organisation A = 1890

Number of employees in organization C = 31% of 35000 

⇒ Number of employees in organization C = 10850

Number of males in organization C = 10850 × \(\frac{3}{3 + 2}\)

⇒ Number of males in organisation C = 6510

Males in organization A ∶ Males in organisation C

⇒ 1890 ∶ 6510 

⇒ 9 ∶ 31

∴ Males in organisation A ∶ Males in organisation C = 9 ∶ 31

The correct option is 4 i.e. 9 ∶ 31

Important Points

Therefore, the correct codes are A - IV, B - III, C - I, D - II

A case study is a comprehensive examination of a single person, group, location, event, organisation, or phenomenon.

Key Points

• Case studies can be used to describe, compare, evaluate, and comprehend various elements of a study subject.
• Case studies are frequently employed in social, educational, clinical, and business research.
• According to Welch et al (2011), the case study as a research method has been dominated mainly as a tool for inductive theory construction, which has limited its theoretical potential.
• A descriptive case study tells the account of a real-life issue that people or organisations faced and how they dealt with it.
• Case studies that are particularistic focus on a specific scenario, event, programme, or phenomenon.
• It focuses attention on the ways in which certain groups of people deal with unique difficulties while taking a holistic view of the situation.

Therefore, C, D and E only are the correct options. 

Additional Information

• The majority of qualitative methods are employed in case study research, but quantitative approaches are occasionally used as well.
• A case study can only represent a small number of people, making generalisation impossible.
• It is a method that is subjective rather than objective.

A fallacy is a type of logical error.

Key Points

• A formal logical fallacy occurs when a categorical syllogism uses two universal premises ("all") to arrive at a specific conclusion ("some").
• The following list of fallacies includes 231 names of the most popular fallacies, as well as brief explanations and illustrations for each.
• Fallacies can be formed unintentionally or with the goal of deceiving others.
• Illicit Major Fallacy occurs when the major word is not dispersed in the premiss but is disseminated in the conclusion.
• It follows the given structure: ​
• All A are B.
• No C is A.
• Therefore, NO C is B
• Rule: In a valid standard-form categorical syllogism no term can be distributed in the conclusion unless it is also distributed in the premises.
• Reason: otherwise the conclusion would assert more than what is contained in the premises.

Therefore, the Illicit Major fallacy is committed in the argument.

Additional Information

• Illicit Minor Fallacy happens when the minor word is not dispersed in the premiss but is distributed in the conclusion.
• It follows the mentioned structure: 
• ​All A are B.
• All B are C.
• Therefore, all C are A.
• Existential Fallacy: ​A formal logical fallacy occurs when a categorical syllogism uses two universal premises ("all") to arrive at a specific conclusion ("some").
• The structure of Existential Fallacy is noted below: 
• All X are Y.
• All Z are X.
• Therefore, some Z are Y.
• ​Undistributed Middle Fallacy: The undistributed middle fallacy is a formal error that occurs when a categorical syllogism's middle term is not distributed in either the minor or major premise

Given:

Total employees = 35000

Calculation:      

Males in organisation A = \(35000 \times \frac{18}{100} \times \frac{3}{3 + 7}\)

⇒ Males in organisation A = 1890

Males in organisation B = \(35000 \times \frac{22}{100} \times \frac{11}{11 + 9}\)

⇒ Males in organisation B = 4235

Males in organisation C = \(35000 \times \frac{31}{100} \times \frac{3}{3 + 2}\)

⇒ Males in organisation C = 6510

Males in organisation D = \(35000 \times \frac{15}{100} \times \frac{2}{2 + 3}\)

⇒ Males in organisation D = 2100

Males in organisation E = \(35000 \times \frac{14}{100} \times \frac{1}{1 + 3}\)

⇒ Males in organisation E = 1225

Total number of males = 1890 + 4235 + 6510 + 2100 + 1225 = 15960

∴ Total number of males in all the five organisations togther is 15960

The correct option is 3 i.e. 15960

Key Points

• In Western philosophy, rationalism is the belief that reason is the primary source and test of knowledge.
• The rationalist claims that there is a class of truths that the intellect may grasp immediately because reality has an intrinsically logical structure.
• Certain logical principles, according to rationalists, exist—particularly in logic and mathematics, but also in ethics and metaphysics.

Logic is just a set of rules and techniques for distinguishing good reasoning from bad. A logic must formulate precise standards for evaluating reasoning and develop methods for applying those standards to particular instances.

Additional InformationDifference between rationalism and empiricism

Therefore, the correct answer is Logic.

Ripple effect.Emotional contagion in groups, or more accurately, the transfer of moods among persons in a group. 

Key Points

• The ripple effect happens when a target student's action or experience has an impact on the behaviour of other pupils.
• The students who are closest to the target student are the ones who are most affected.
• The influence can be negative (for example, a student misbehaves and others copy) or positive (for example, a student misbehaves and others copy) (a student is on-task or follows an instruction, and others copy).
• The ripple effect has been studied for decades and is a well-known impact among educators
• The clarity and firmness of the correction have an impact on the ripple effect.
• When the teacher explicitly names the incorrect behaviour and explains why it must stop, the effect is amplified.

Therefore, the Contagious spreading of behaviours through imitation is known as the Ripple effect.

Additional Information

• Norm Effect is the action-effect that can be explained by normality which states that actions are more abnormal than inactions.
• Norms are socially shared beliefs about behaviour; they differ from "ideas," "attitudes," and "values," which might be held privately and do not always concern behaviour.

A computer network is a collection of two or more computers that are linked together to exchange data electronically.

Key Points Assertion A: A good computer networking solution can be very much beneficial for your business.

• A computer network system that allows a range of equipment types to transfer information in a near-seamless manner.
• A good computer networking solution might be extremely advantageous for business. : 
• ​It allows companies to store data in one place.
• This allows the network's many computers to retrieve essential data from the central server.
• Computer networking allows you to access data from other computers on the same network and edit it as needed.

​So, Assertion A is a correct statement. 

Reason R: With computer networking, you can cut back on costs and allow for efficient use of resources.

• Storing data in a single, central database can also help you save money and improve productivity.
• For Example:
• Because employees have shared access to customer and product databases, they can serve more customers in less time.
• You can centralise network administration, which means you'll need less IT help.
• Sharing peripherals and internet access can help you save money.

Therefore, Reasons R is the correct statement and correct explanation of A. 

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

Additional Information

• The two most common network kinds are Local-area networks (LANs) and wide-area networks (WANs).
• LANs use links to connect computers and peripheral devices in a limited physical area, such as a corporate office, laboratory, or college campus.
• WANs link computers and smaller networks to larger networks across wider geographic areas.
• They may connect the computers through cables, optical fibres, or satellites, although most users access the networks with a modem

Given:

Total employees = 35000

Calculation:    

Number of employees in organization C = 31% of 35000 

⇒ Number of employees in organization C = 10850

Number of employees in organization D = 15% of 35000 

⇒ Number of employees in organization D = 5250

Now,

5250 × x% = 10850

⇒ x = \(\frac{10850}{5250}\times 100\)

⇒ x = 206.66%

⇒ x = 207% approx

∴ The total number of employees in Organisation C is approximately 207% of the total number of employees in Organisation D

The correct option is 3 i.e. 207%

Nonverbal cues are nonverbal indications that people use to communicate without using words. 

Key PointsStatement I: People use non-verbal cues more than verbal cues.

• Nonverbal cues can also be used to supplement the meaning of verbal communication.
• It's also crucial to be conscious of the messages your body language may be delivering to others.
• Dr Albert Mehrabian, a prominent behavioural psychologist**, was one of the first to advocate for the importance of nonverbal communication.**
• The 7-38-55 rule was developed as a result of Mehrabian's considerable research on the subject of body language.
• According to the 7-38-55 rule, verbal communication accounts for only 7% of all communication, whereas nonverbal components of our daily conversation, such as voice tonality and body language, account for 38% and 55%, respectively.

​So, the statement I is True. 

Statement II: Non-verbal cues have better believability than spoken words.

• Nonverbal communication cues are the way you listen, look, move, and react tell the other person whether or not you care if you're being truthful, and how effectively you're listening.
• Nonverbal communication is frequently more credible than verbal communication.
• Nonverbal cues, such as gestures that signify certain phrases like "yes" and "no," can sometimes take the role of language.
• Their meaning is embedded in clues such as discomfort, disinterest, and disapproval, producing uncertainty, bewilderment, or unease.

​Thus, the statement is True. 

Therefore, Both Statement I and Statement II are true. 

Additional Information

• There are various types of nonverbal communication which are mentioned below: 
• ​Facial Expression
• Kinesics (Body Movement)
• Eye Contact
• Haptics (Touch)
• Proxemics (Space)
• Paralinguistics
• Props and Physical Appearance
• Chronemics (Time)

The United Nations Conference on Sustainable Development in Rio de Janeiro in 2012 gave birth to the Sustainable Development Goals (SDGs).

Key Points

• The Sustainable Development Goals (SDGs) are a bold pledge to finish what the Millennium Development Goals (MDGs) started and address some of the world's most critical issues.
• All 17 goals are interconnected and achieving one pushes you to achieve the others.
• "Sustainable development" is defined as "development that meets current demands without jeopardizing future generations' ability to meet their own needs."
• Sustainable development has a far broader scope than merely the environment.
• It's also about ensuring that society is robust, healthy, and just.
• This entails satisfying the different needs of all individuals in current and future communities, as well as encouraging personal well-being, social cohesion, and inclusion, and ensuring equitable opportunity.

Therefore, SDG 12  is related to sustainable consumption and production patterns. 

Additional Information

• "Future We Want," a documentary played at the Rio+20 meeting proposed a post-2015 development agenda.
• The Sustainable Development Goals (SDGs) are an intergovernmental agreement that replaces the Millennium Development Goals as the post-2015 development agenda.
• The United Nations Sustainable Development Summit established a post-negotiation agenda named *Transforming Our World: the 2030 Agenda for Sustainable Development.*​​**

Important Points

• ​​​​The Rio+20 summit (2012) in Rio de Janeiro produced the Sustainable Development Goals (SDGs) is a non-binding document.​

Given:

Total employees = 35000

Calculation:    

Number of employees in organization E = 14% of 35000 

⇒ Number of employees in organization E = 4900

Number of females in organization E = 4900 × \(\frac{3}{3 + 1}\)

⇒ Number of females in organisation E = 3675

Number of employees in organization B = 22% of 35000 

⇒ Number of employees in organization B = 7700

Number of females in organization B = 7700 × \(\frac{9}{11+ 9}\)

⇒ Number of females in organisation B = 3465

⇒ Difference = 3675 - 3465 = 210

∴ The difference between the number of females in Organisation E and the number of females in Organisation B is 210

The correct option is 2 i.e. 210

In education, measurement error refers to the discrepancy between a test result and a student's real knowledge and abilities and inaccuracies introduced during the collection and calculation of data-based reports, figures, and statistics about schools and students.

Key Points

• Although some degree of measurement error is unavoidable in testing and test developers frequently publicly admit that performance data, such as high school graduation rates or college enrollment rates, are not always accurate.
• The True score represents the person's true ability, whereas the Observed score is the exam's actual score.
• The disparity between observed and true scores is known as error.
• Measurement inaccuracies in testing can be caused by a range of reasons, including a student's mental and emotional state during the test time or the test's administration conditions.
• Due to error, these observed scores won’t necessarily be equal; some scores will be high and others low.
• If you count the number of times each of the student’s observed scores occurs and graph those counts, you’ll get a bell-shaped curve of observed scores for the student.

Therefore, the True score the student would get if the measurements were completely accurate and error-free. 

Additional Information

• When a student just takes the algebra test once, the result is referred to as an observed score.
• When the stakes for test performance climb, measurement inaccuracy becomes a more serious issue.
• Many test makers and testing specialists advise against utilising a single test result to make crucial educational decisions due to measurement inaccuracy.

Nonverbal communication types include facial expressions, gestures, paralinguistics such as loudness or tone of voice, body language, proxemics or personal space, eye gaze, haptics (touch), appearance, and artifacts.

Important PointsStatement I: In all interactions, a message is sent and a message is received. Sometimes teachers believe they are sending one message, but her voices, body language, choice of words, and gestures may communicate a different message.

• When we think of communication, we usually think of how we exchange data through words.
• While verbal communication is vital, nonverbal communication has been used by humans for thousands of years before we gained the ability to communicate with words.
• Nonverbal communication is a method of conveying information without using words.
• Rather than seeing nonverbal communication as the polar opposite of or distinct from verbal communication, it's more accurate to think of both as part of the same system.
• Even though they are part of the same system, they have significant differences, such as how the brain processes them.

Hence, this statement is correct.

Statement II: To deal with cyberbullying, parents should be encouraged to keep computers in a public room in the house.

• When someone utilises technology to harass, threaten, embarrass, or target another person, it is known as cyberbullying.
• It occurs on a variety of devices, including smartphones, desktops, tablets, and game consoles.
• Many bullied adolescents can't resist the desire to check websites or phones to see if there are new messages, even when it's upsetting.
• Limiting the use of cellphones and video games by keeping the computer in a public area of the house.
• One may be able to disable text messaging services during specific hours, and most websites, apps, and cellphones contain parental control features that allow parents to monitor their children's communications and online activities.
• Many bullied adolescents can't resist the desire to check websites or phones to see if there are new messages, even when it's upsetting.
• Limit the use of cellphones and video games by keeping the computer in a public area of the house.
• Parents may be able to disable text messaging services during specific hours, and most websites, apps, and cellphones contain parental control features that allow parents to monitor their children's communications and online activities.

Hence, this statement is correct.

Therefore, the correct answer is Both Statement I and Statement II are correct.

The reliability of a statistical analysis conveys that a methodology being used for interpreting data is consistent and would give uniform results every time it is used.

Key Points Quixotic Reliability:

• Quixotic reliability can be viewed as an attempt to measure how far a particular method can continuously lead to the same measurements and final results.
• However, many researchers and authors have rejected this approach of defining reliability as misleading and trivial.

Diachronic Reliability:

• Diachronic reliability is understood as the stability of measurements or observations in their temporal course.
• The issue here is the precondition that the phenomenon under study in itself may not undergo any changes so that the criterion remains effective.

Synchronic Reliability:

• Synchronic reliability is the consistency of results collected at the same moment in time but by using different instruments.
• This criterion is most instructive when it is not fulfilled as viewed by various researchers.
• The issue then follows as to why this is the case and also brings out questions concerning the various perspectives on the issue resulting from different methods applied by numerous researchers.

Additional Information Difference between validity and reliability.

Therefore, the correct answer is A, B, and C only.

Given:

Salary increased = 20%

Tax rate increase = 10% on increased salary

Calculation:     

Let assume that salary is 100

And tax is 100

Now, 

Increased salary = 100 + 20% = 120

New tax liability = Tax on previous salary + Tax on increased salary

Tax liability = 100 + 20 (100 + 10)%

⇒ Tax liability = 100 + 20 × 110%

⇒ Tax liability = 100 + 22 = RS. 122

Increase in tax liability = 122 - 100 = Rs. 22

% increase in tax liability = \(\frac{Increment\space in\space tax}{Previous\space tax} \times 100\)

⇒ % increase in tax liability = \(\frac{22}{100} \times 100\)

⇒ % increase in tax liability = 22%

∴ The percentage increase in tax liability is 22%

The correct option is 2 i.e. 22%

Given:

Formula Used:

Calculation:  

Let's assume his weight is x lbs

According to the question:

⇒ x = 75% of x + 39    

⇒ x - \(\frac{75x}{100}\) = 39

\(⇒ \frac{x}{4} = 39 \)

By crossmultiplication

⇒ x = 39 × 4 

⇒ x = 156 lbs

∴ He weighs 156 lbs.

The correct option is 1 i.e. 156 lbs.
