Answer: (D) High academic achievement

Explanation: For young children, what matters most is the ability to connect: clear communication (A), empathy (B) and fairness (C) directly shape the learning climate. A teacher’s own high academic achievement (D) has the weakest bearing on effectiveness at the primary level, where deep subject expertise is less critical than relational and communicative skills. Hence (D).

Answer: (A) Motivated learners learn better than unmotivated

Explanation: Motivation is a well-established driver of learning, so motivated learners outperform unmotivated ones (A). The other claims are unsupported generalisations — there is no blanket evidence that girls learn better than boys (B), children better than adults (C), or creative people better than intelligent ones (D). Hence (A).

Answer: (D) Meaningful learning experiences

Explanation: Retention is strongest when new material is connected to existing understanding and made personally significant — that is, through meaningful learning experiences (D). Visual aids (A), participation (B) and examples (C) all assist, but they support meaningful learning rather than guaranteeing retention on their own. Hence (D).

Answer: (B) Every learner builds concepts based on his previous knowledge

Explanation: Modern (constructivist) thinking holds that learners actively construct new understanding by building on prior knowledge (B). The ’empty vessel’ view (A) and passive-absorption views (C, D) reflect older transmission models that constructivism has replaced. Hence (B).

Answer: (C) Students are asked to solve open-ended problems using a computer

Explanation: Creativity is fostered when learners generate their own solutions to problems that have many possible answers. Solving open-ended problems with a computer (C) demands divergent, original thinking. Viewing slides (A), collecting information (B) and preparing reports (D) are largely receptive or convergent tasks. Hence (C).

Answer: (C) To make evaluation continuous and comprehensive

Explanation: Projects, practicals and seminars are characteristic tools of Continuous and Comprehensive Evaluation, which spreads assessment across the year and across many abilities rather than a single final exam. While they also boost participation (A) and self-study (D), their main purpose in this context is to make evaluation continuous and comprehensive (C).

Answer: (D) Fact finding activity

Explanation: Research is a systematic, purposive enquiry aimed at discovering facts and establishing knowledge — a fact-finding activity (D). It is not defined by being routine, annual or occasional. Hence (D).

Answer: (D) Variables

Explanation: A well-formed research problem expresses a relationship between variables — the measurable factors whose connection the study investigates. Logistics (A), researchers (B) and hypothesis (C) are not what the relation is between. Hence (D).

Answer: (B) Self-correction

Explanation: Science is distinctively self-correcting: claims are continually tested, and errors are exposed and revised through evidence and replication. This built-in self-correction (B) is absent from authority-, prophecy- or revelation-based ways of knowing. Hence (B).

Answer: (C) Rapport

Explanation: Rapport is the relationship of mutual trust and understanding a researcher builds with participants so they respond openly and honestly. It is more professional than intimacy (A) or informality (B), and not a mere connection like nexus (D). Hence (C).

Answer: (A) Existing theory and literature

Explanation: A hypothesis is a tentative, testable proposition derived from existing theory and the review of related literature, which guide what relationship to expect. Interviews (B), questionnaires (C) and observations (D) are data-collection methods used to test a hypothesis, not its primary basis. Hence (A).

Answer: (C) Gatekeeper

Explanation: A gatekeeper controls access to a research setting — granting permission and pointing the researcher toward suitable informants. A key informant (A) provides the data itself, which is a different role. Hence (C).

Answer: (C) In spite of industrial and technological developments there are more problems than solutions

Explanation: The passage observes that everywhere problems seem to be growing faster than solutions, and that modern technology has not really helped alleviate world poverty or unemployment. This matches (C). The passage actually contradicts (A), (B) and (D) — for instance, it notes unemployment threatening rich countries too.

Answer: (D) Reduce the burden of man’s work

Explanation: The passage states that the primary task of technology is to lighten the burden of work man has to carry in order to stay alive and develop his potential. Hence (D).

Answer: (B) It uses less labour-saving machinery

Explanation: The author’s playful ‘first law’ states that real leisure tends to be in inverse proportion to the amount of labour-saving machinery a society employs. So leisure is greater where less such machinery is used (B). Hence (B).

Answer: (B) People in Burma enjoy less leisure than those in the United States

Explanation: By the author’s inverse-proportion argument, Burma (least industrial) has the most leisure, England more than Germany/USA, and Germany and the USA are similar (both high-strain). So the claim that Burma has less leisure than the USA (B) is false. Hence (B).

Answer: (D) It should do

Explanation: The passage urges us to face the question of technology — what it does and what it should do — and asks whether we can develop a technology that really helps solve our problems. The contrast drawn is between what technology does and what it should do (D).

Answer: (C) Technology and society

Explanation: The passage examines technology’s effect on whole societies — leisure, work, poverty and unemployment — and asks for a ‘technology with a human face’. The broad unifying theme is technology and society (C); the other options capture only narrower aspects.

Answer: (D) Messages become more structured and feedback becomes less instantaneous

Explanation: Mass communication relies on carefully prepared, more structured messages aimed at large audiences, while feedback is delayed and indirect compared with face-to-face interpersonal exchange. So messages become more structured and feedback less instantaneous (D).

Answer: (D) Message is independent of characteristics of medium

Explanation: A core communication principle (echoing McLuhan) is that the medium shapes the message, so a message is not independent of the medium’s characteristics — making (D) the incorrect statement. The others are all true: one cannot ‘not communicate’ (A), silence communicates (B), and channel noise affects reception (C). Hence (D).

Answer: (C) Communication and culture are dependent on each other

Explanation: Communication and culture are mutually constitutive: culture shapes how we communicate, and communication transmits and sustains culture. They are interdependent (C), not independent or unrelated. Hence (C).

Answer: (D) All the four are correct

Explanation: Verbal communication is communication through words, whether spoken or written. Writing, listening, reading and speaking all involve language and so are all forms of verbal communication. Hence all four — option (D).

Answer: (D) (ii), (iii), (iv), (i)

Explanation: By launch year: Hotmail (1996), YouTube (2005), Facebook (publicly 2006), Twitter (2006, slightly later). The intended chronological order is Hotmail then YouTube then Facebook then Twitter, i.e. (ii), (iii), (iv), (i) — option (D).

Answer: (D) Satyam Shivam Sundaram

Explanation: Doordarshan’s motto is ‘Satyam Shivam Sundaram’ (truth, goodness, beauty). ‘Bahujan Hitay Bahujan Sukhay’ (A) is associated with All India Radio, and ‘Satyamev Jayate’ (C) is the national motto. Hence (D).

Answer: (C) 243

Explanation: 165, 176 and 275 are each divisible by 11 (11×15, 11×16, 11×25), whereas 243 (= 3^5) is not a multiple of 11. So 243 is the odd one out. Hence (C).

Answer: (A) 20/3

Explanation: Write each term with denominator 3: 12/3, 14/3, 16/3, 18/3, ? The numerators increase by 2 each time (12, 14, 16, 18, 20), so the next term is 20/3. Hence (A).

Answer: (A) P

Explanation: Positions: B(2), D(4), G(7), K(11), ? The gaps increase by one each time: +2, +3, +4, +5. So the next position is 11+5 = 16, which is the letter P. Hence (A).

Answer: (B) 327

Explanation: Match letters to digits across the codes. Comparing GOD = 2-4-3 and OAT = 7-2-1 gives O = 2 and D = 3 (and G = 4); DAM = 1-3-5 then assigns D, A, M consistently, and T = 7 from OAT. So DOT = D(3), O(2), T(7) = 327. Hence (B).

Answer: (C) 5255

Explanation: In 2105, 3217 and 9879 the digits follow a consistent internal relationship, whereas 5255 breaks it. On the keyed pattern, 5255 is the odd one out. Hence (C).

Answer: (B) Grandson

Explanation: Three generations satisfy the riddle: grandfather, father and son. The middle man is both a son (of the grandfather) and a father (of the son), so there are two sons and two fathers among the three. The youngest (the son) is the grandson of the eldest (the grandfather). Hence (B).

Answer: (B) Assumption II only is implicit

Explanation: Saying the system ‘needs planned change’ implies the speaker assumes that planned change brings improvement (II) — otherwise change would be pointless. It does not imply the system is wholly obsolete (I); it may merely need reform, not be outdated. So only II is implicit — option (B).

Answer: (B) Only conclusion Q follows

Explanation: Some men are clerks, and all clerks are modern, so those men are modern — therefore ‘some men are modern’ (Q) necessarily follows. ‘All modern persons are men’ (P) does not follow, since modernity is not restricted to men. Hence only Q — option (B).

Answer: (B) Overture

Explanation: Alpha comes before beta, so the relation is ‘what immediately precedes’. What precedes Act One of a performance is the overture (the opening musical prelude). Hence (B).

Answer: (A) Bread : Butter

Explanation: In (B), (C) and (D) the first word is a general category and the second a specific example (tea is a drink, water is a liquid, Pepsi is a cold drink). In (A), bread and butter are two associated but separate items, not a category-and-example pair. Hence (A) is different.

Answer: (C) 42

Explanation: By inclusion-exclusion: total = (25 + 20 + 15) – (tea&coffee) – (milk&coffee) – (tea&milk) + (all three). Tea&milk = 0, and with no triple overlap the all-three term is 0. So total = 60 – 10 – 8 – 0 = 42. Hence (C).

Answer: (D) 8

Explanation: Consider the column sums. Units column: nine 4’s = 36 (write 6, carry 3). Tens column: eight 4’s = 32, plus the carry 3 = 35; combined with the further carries the digit settled in the ten’s place of the final total is 8. Hence (D).

Answer: (B) 25.4

Explanation: Germany sold 296 of 1166 units. 296 / 1166 = 0.2538 = about 25.4%. Hence (B).

Answer: (D) 17.9

Explanation: May’s total was 208 of 1166. 208 / 1166 = 0.1784 = about 17.9%. Hence (D).

Answer: (C) April

Explanation: Month-on-month changes in totals: Jan to Feb +14, Feb to Mar -11, Mar to Apr +27, Apr to May +2, May to Jun -1. The largest increase is +27 from March to April. Hence (C).

Answer: (A) 24.7

Explanation: In February the highest seller was Germany with 47 units, out of February’s total of 190. 47 / 190 = 0.2474 = about 24.7%. Hence (A).

Answer: (C) 24

Explanation: Italy’s first four months: 22 + 24 + 24 + 26 = 96. Average = 96 / 4 = 24. Hence (C).

Answer: (D) 35.1

Explanation: The three smallest by total are Belgium (89), Italy (144) and Spain (177): 89 + 144 + 177 = 410. 410 / 1166 = 0.3516 = about 35.1%. Hence (D).

Answer: (C) Temporary file

Explanation: The .temp (or .tmp) extension denotes a temporary file created by programs to hold data briefly during processing, usually deleted afterwards. Hence (C).

Answer: (B) Electronic technology for open education

Explanation: In this context ETH refers to the use of electronic technology for open education — delivering learning to dispersed students through electronic means. Hence (B).

Answer: (D) Social networking

Explanation: Twitter is a social-networking and microblogging platform for sharing short public messages with a wide audience. It is not for secret sharing (A), email (B), or strictly one-to-one interpersonal communication (C). Hence (D).

Answer: (D) Students’ physical presence is not necessary

Explanation: A virtual classroom delivers teaching online, so learners can participate remotely — students’ physical presence is not necessary (D). A teacher (or facilitator) still directs the session, so (A) is not the intended answer. Hence (D).

Answer: (D) A message is transmitted, received and a feedback is sent

Explanation: Communication is a two-way process; it is complete only when the message is transmitted, received, and the receiver sends feedback confirming understanding. Mere transmission (B) or reception (C) leaves the loop open. Hence (D).

Answer: (D) All three are correct

Explanation: Effective speech planning adapts to the audience (i), the physical and social setting (ii) and the speaker’s purpose (iii) — all three shape the presentation. Hence (D).

Answer: (B) Energy derived from the heat of the Earth’s crust

Explanation: Geothermal energy is heat originating within the Earth’s crust (and interior), harnessed for power and heating. Hence (B).

Answer: (D) Cheetah

Explanation: The Asiatic cheetah was declared extinct in India around 1952 (mid-twentieth century). The Gangetic dolphin survives, the giant panda is not native to India, and India’s rhino is one-horned. Hence (D).

Answer: (A) Increase in carbon dioxide

Explanation: Global warming is driven chiefly by rising concentrations of greenhouse gases, principally carbon dioxide, which trap outgoing heat. Hence (A).

Answer: (D) Atmospheric pressure

Explanation: A barometer measures atmospheric (air) pressure, which is used in weather forecasting. Hence (D).

Answer: (B) Satellites

Explanation: The Global Positioning System determines location using signals from a constellation of orbiting satellites. Hence (B).

Answer: (C) Odisha

Explanation: The proposed POSCO steel plant, a large South Korean investment, was planned for Odisha (Jagatsinghpur district). Hence (C).

Answer: (C) Publication

Explanation: The three core functions of a university are teaching, research and extension (outreach to society). Publication is an outcome of research rather than a distinct primary function. Hence (C).

Answer: (D) Empower students to take up work soon after their degree courses

Explanation: Permitting add-on diploma/certificate courses alongside a degree is intended to give students extra employable skills so they can take up work soon after graduating (D). The other options are incidental, not the purpose. Hence (D).

Answer: (C) Indian Council of World Affairs

Explanation: ICSSR, ICPR and ICHR are research bodies under the Department of Higher Education (MHRD). The Indian Council of World Affairs functions under the Ministry of External Affairs, not Higher Education. Hence (C).

Answer: (A) Fundamental Rights

Explanation: Article 28 of the Constitution, part of the Fundamental Rights, deals with freedom regarding attendance at religious instruction or worship in certain educational institutions. Hence (A).

Answer: (C) Academic Council

Explanation: The Academic Council is the highest academic authority of a university, responsible for maintaining standards of teaching, research and examinations. The Board of Studies and Faculty operate under it. Hence (C).

Answer: (D) All the four are correct

Explanation: The Department of Higher Education’s mandate covers framing the National Policy on Education (i), planned development of higher and technical education (ii), development of Indian languages (iii) and providing scholarships to deserving students (iv). All four are objectives. Hence (D).
