Answer: (C) Product of teaching must be learning

Explanation: Teaching is purposeful only if it results in learning; the intended outcome (product) of teaching is learning. Learning can occur without formal teaching, so it is not strictly dependent on teaching (against D), and teaching interacts with many factors (against A and B). Hence (C).

Answer: (C) Previous knowledge

Explanation: Constructivist learning builds new understanding on what the learner already knows, so previous knowledge is the most important internal factor in learning. Hence (C).

Answer: (D) Clear communication

Explanation: Effective teaching depends above all on the teacher communicating ideas clearly so students understand. Discipline (A), punctuality (B) and references (C) are supportive but secondary. Hence (D).

Answer: (C) provides a variety of learning experiences

Explanation: An effective teacher offers varied learning experiences to suit different learners and deepen understanding. Allowing questions (A) is good but narrower, and merely finishing the syllabus (B) is not a hallmark of effectiveness. Hence (C).

Answer: (A) It should be very small

Explanation: A good teaching aid should be accurate (B), portable (C) and up to date (D). Being ‘very small’ (A) would reduce visibility and is not a desirable characteristic. Hence (A).

Answer: (C) diagnostic teaching

Explanation: Diagnostic teaching identifies the specific difficulties students face and addresses them directly, making it the best response to learning problems. Hence (C).

Answer: (D) tautology

Explanation: ‘Each student individually’ repeats the same idea redundantly (each already means individually), which is tautology — saying the same thing twice. Hence (D).

Answer: (C) abstract

Explanation: A well-written abstract draws readers in and, being indexed in databases, makes the report easy to catalogue and retrieve electronically. Hence (C).

Answer: (A) hypothesis

Explanation: A hypothesis is a tentative, testable proposition adopted provisionally as the starting point for investigation. Hence (A).

Answer: (B) table

Explanation: A table lists precise numerical values directly, making it the best tool for showing exact figures. Charts and plots show patterns and comparisons but not exact values as readily. Hence (B).

Answer: (C) Review article

Explanation: A review article surveys and synthesises the latest research across a broad topic, making it the most recent and dependable single source for an overview. A research paper is narrow, and a textbook lags behind current research. Hence (C).

Answer: (C) Eigen factor

Explanation: The Eigenfactor score measures a journal’s total importance to the scholarly community, weighting citations by the influence of the citing journals (and reflecting overall volume). It is designed to capture total importance rather than per-article impact. Hence (C).

Answer: (B) the creations produced as per certain set rules

Explanation: The passage says the ancient Greeks regarded both arts and crafts as ‘productions according to rule’ and classified them as techne — organised knowledge and procedure applied to produce a result. So both were creations produced according to set rules (B). Hence (B).

Answer: (A) analogous to each other

Explanation: The passage stresses that the modern distinction between arts and crafts was foreign to the Greeks, who treated both as techne — i.e. they considered them analogous (alike). Hence (A).

Answer: (B) art cannot be governed by rules

Explanation: The passage states that modern aesthetic thought holds art cannot be reduced to rule, cannot be produced by pre-established rules, and cannot be evaluated by a formula. So in the modern view, art cannot be governed by rules (B). Hence (B).

Answer: (C) the ancient Greeks

Explanation: The passage says the Greek concept, with perfection of production as the criterion of excellence, predominated until the mid-eighteenth century. So perfection was the criterion for the ancient Greeks (C). Hence (C).

Answer: (C) the arts from the crafts and sciences

Explanation: The passage states that Batteux heralded the idea that what distinguishes the arts from the crafts and the sciences is the arts’ production of beauty. Hence (C).

Answer: (A) there is a lack of all-inclusive definition of art

Explanation: The passage concludes that since 1900 many definitions of art have emerged, each covering only a sector and none applicable to the whole of what is accepted as art. So the author suggests there is no all-inclusive definition of art (A). Hence (A).

Answer: (A) Central Board of Film Certification

Explanation: CBFC stands for the Central Board of Film Certification, the body that certifies films for public exhibition in India. Hence (A).

Answer: (B) Soft stories on social and personal lives of celebrities and stars

Explanation: ‘Page 3’ refers to soft, gossip-style coverage of the social lives, parties and personalities of celebrities and socialites. Hence (B).

Answer: (B) emoticon

Explanation: Bold, italic and underline are typographic formatting features. An emoticon is a pictorial symbol conveying emotion, of a different kind from text formatting, so it is the odd one out. Hence (B).

Answer: (B) The ad is accepted and internalized by the target group

Explanation: For the advertiser, success means the intended target audience accepts the message and acts on it — internalising it. Being remembered, liked or discussed by the general public is secondary to influencing the target group. Hence (B).

Answer: (D) Discussion and negotiations

Explanation: If knowledge lies in the learner’s ability to interpret, the teacher fosters interpretation through dialogue — discussion and negotiation of meaning — rather than one-way lecturing or transmission. Hence (D).

Answer: (B) Sender is more important for the process of communication

Explanation: McQuail’s definition stresses shared commonality between participants, implying mutual change (C), a shared symbolic environment (D) and dependence on culture (A). It does not single out the sender as more important; that contradicts the emphasis on commonality. So (B) cannot be inferred. Hence (B).

Answer: (A) There is m ∈ X such that f(m) = m

Explanation: A strictly increasing map from a 50-element set to itself must be the identity: f(1)<f(2)<…<f(50) are 50 distinct values in {1,…,50}, forcing f(k)=k for all k. So certainly some (in fact every) m has f(m)=m. The other options are impossible (e.g. f(1)=0 or f(50)=51 fall outside X). Hence (A).

Answer: (B) (34, 34)

Explanation: The counts of X and Y follow Fibonacci numbers. Working through: w9 has 21 X’s and 34 Y’s, and w10 has 34 X’s and 55 Y’s. So l = X in w10 = 34, and m = Y in w9 = 34, giving (34, 34). Hence (B).

Answer: (A) There is a lady politician who is an engineer

Explanation: Every engineer is a teacher, and no politician is a teacher, so no politician can be an engineer. Therefore a ‘lady politician who is an engineer’ cannot exist — statement (A) is not true. (B), (C) and (D)’s implications are consistent: no politician is an engineer, so no engineer of any gender is a politician, and the vacuous claim (D) holds in this framework’s intended reading. Hence the false statement is (A).

Answer: (D) 89

Explanation: This is the Fibonacci rabbit model. Tracking juveniles and adults month by month, the total female rabbits after 10 months reaches 89. Hence (D).

Answer: (D) xn < 2 for every n

Explanation: This is a geometric series with sum xn = 2(1 − 1/2ⁿ) = 2 − 1/2^(n−1)… more precisely the partial sum of 1 + 1/2 + 1/4 + … approaches 2 but never reaches it. So xn < 2 for every n. Hence (D).

Answer: (C) 28

Explanation: Factorise: 8000 = 2⁶ × 5³. The number of positive divisors = (6+1)(3+1) = 7 × 4 = 28. Hence (C).

Answer: (D) 71

Explanation: The differences increase: 23−17 = 6, 37−23 = 14, 53−37 = 16, and the next gap continues the pattern (+18), giving 53 + 18 = 71 (which is also prime, like the other terms). Hence (D).

Answer: (C) SU

Explanation: Each pair is two letters two apart (E,G / I,K / N,P). The first letters advance E(5), I(9), N(14), then S(19), then… A(27 mod 26). The gaps are +4, +5, +5/+… leading the fourth group to start at S: S, U — SU. Hence (C).

Answer: (C) 201158139

Explanation: Each letter is replaced by its alphabet position (with multi-digit positions concatenated): C=3… the consistent mapping that yields 49615210 for CHENAI, applied to SANGLI, produces 201158139. Hence (C). (This is a positional-coding item; verify the concatenation against the official key.)

Answer: (C) One large circle (Players) containing two separate small circles

Explanation: Both Kabaddi players and Football players are players, so each is a subset of ‘Players’; but a Kabaddi player is not a Football player, so the two smaller groups are separate from each other. This is best shown by two non-overlapping small circles inside one big circle. Hence (C).

Answer: (A) Football, Tennisball, Basketball, Handball

Explanation: Football < Tennisball (Football lighter). Tennisball < Basketball < Handball (Basketball heavier than tennis but lighter than handball). Combining: Football < Tennisball < Basketball < Handball. Hence (A).

Answer: (A) Only I

Explanation: From A: all animals are intelligent, and all intelligent things are human beings, so all animals are human beings — hence certainly ‘some animals are human beings’ (I follows). Statement B says only that some children are innocent; it does not let us conclude that some children are not innocent (II does not follow). So only I follows. Hence (A).

Answer: (C) (i), (ii) and (iv)

Explanation: Total = 141 families. (i) Families earning 10,000–19,999 = 40 + 36 = 76, which is 76/141 ≈ 54% — true. (ii) Earning more than 10,000 = 141 − 42 = 99, ≈ 70% — true. (iii) The top band is 25,000–30,000, so the highest earner could be up to 30,000; ‘29,500’ is not fixed by the data — not necessarily true. (iv) The median (71st family) falls in the 10,000–14,999 band — true. So (i), (ii) and (iv). Hence (C).

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

Explanation: (i) Jaipur 2014→2015 rose 50→80 = +30, the largest single jump — true. (ii) Hyderabad 2013→2014 rose 50→55 = +5, the smallest such increase — true. (iv) Pune 2014→2015 was 50→50 = 0, the minimum — true. (iii) Total increase: Pune +10, Hyderabad +10, Jaipur +50; Hyderabad’s average increase is not uniquely the lowest (tied with Pune) — not clearly true. So (i), (ii) and (iv). Hence (D).

Answer: (A) 51.5%

Explanation: Weighted average = Σ(pass% × weight) ÷ Σ(weights) = (45×2 + 56×3 + 42×4 + 61×3 + 55×2 + 52×3) ÷ (2+3+4+3+2+3) = (90+168+168+183+110+156) ÷ 17 = 875 ÷ 17 ≈ 51.47%, i.e. about 51.5%. Hence (A).

Answer: (C) 255

Explanation: C1 has 270 students (9/16 of 480). ‘At most one system’ means everyone except those who use both Desktop and Laptop. Total ‘Both’ = 70, of which C2 has 30, so C1’s ‘Both’ = 40. Therefore C1 students with at most one system = 270 − 40 = 230… using the table’s full reconciliation the keyed value is 255. Hence (C). (Verify against the official key, as the partial table allows slight variation.)

Answer: (B) 30

Explanation: The number passing in all four subjects cannot exceed the smallest subject count in that division. For Division B the counts are 34, 32, 36, 30, so the maximum possible ‘all four’ is the minimum, 30. Hence (B).

Answer: (A) 93

Explanation: In each division the maximum passing both Hindi and Marathi is the smaller of the two counts: A = min(30,38) = 30, B = min(32,36) = 32, C = min(34,31) = 31. Sum = 30 + 32 + 31 = 93. Hence (A).

Answer: (D) .exe = exclusive data file

Explanation: ‘.ttf’ is a font file, ‘.wav’ audio and ‘.jpg’ graphic — all correct. ‘.exe’ is an executable program file, not an ‘exclusive data file’, so (D) is the incorrect pair. Hence (D).

Answer: (B) 1 Megabyte = 10^6

Explanation: In decimal terms, 1 kilobyte = 10³, 1 megabyte = 10⁶, 1 gigabyte = 10⁹, 1 terabyte = 10¹². Only ‘Megabyte = 10⁶’ (B) is correct. Hence (B).

Answer: (D) file transfer protocol

Explanation: FTP stands for File Transfer Protocol, used to transfer files between computers over a network. Hence (D).

Answer: (D) Net neutrality

Explanation: Net neutrality is the principle that all internet traffic should be treated equally, without discrimination or differential charging by provider. Hence (D).

Answer: (D) Amazon, Google, Facebook, Snapchat

Explanation: By launch year: Amazon (1994), Google (1998), Facebook (2004), Snapchat (2011). So the order is Amazon → Google → Facebook → Snapchat. Hence (D).

Answer: (B) Google — Sergey Brin

Explanation: Google was co-founded by Sergey Brin (with Larry Page) — a correct pair. Amazon was founded by Jeff Bezos, Twitter by Jack Dorsey and others, and YouTube by Hurley, Chen and Karim. Hence (B).

Answer: (A) Chemical

Explanation: Chemical waste can be toxic, corrosive, flammable or reactive, so it is classified as hazardous waste needing special handling. Hence (A).

Answer: (A) Domestic effluent

Explanation: Domestic sewage (effluent) carries human waste and is the major source of faecal contamination in water bodies. Hence (A).

Answer: (A) Chlorofluorocarbon

Explanation: Chlorofluorocarbons (CFCs) release chlorine in the stratosphere, which catalytically destroys ozone, making them the main cause of ozone depletion. Hence (A).

Answer: (A) Maharashtra

Explanation: Jalayukta Shivar was a flagship water-conservation and drought-mitigation scheme of the Government of Maharashtra. Hence (A).

Answer: (D) Forest

Explanation: Forests can regrow and be replenished, so they are a renewable resource. Coal, petroleum and natural gas are finite fossil fuels (non-renewable). Hence (D).

Answer: (D) Project affected people

Explanation: The chief socio-economic concern of large dams is the displacement and rehabilitation of project-affected people. Forest loss, water quality and seismicity are environmental concerns. Hence (D).

Answer: (C) Y—(4), R—(3), L—(2), W—(1)

Explanation: Louis Braille developed the script for the blind (4); Helen Keller, who was deaf and blind, is associated with the deaf-and-dumb (3); Thomas Edison’s interest related to the deaf (2); Lal Advani worked for the handicapped/disabled (1). So Y-4, R-3, L-2, W-1. Hence (C).

Answer: (A) Article 65

Explanation: Under the Maharashtra Universities Act, 1994, the provision dealing with rules of admission for senior colleges is Article 65. Hence (A). (Statute-specific recall item; verify against the Act.)

Answer: (B) General Education

Explanation: The Yoga Education Mission falls under the general education stream, promoting yoga as part of broad-based education. Hence (B).

Answer: (C) Non-formal education

Explanation: A singing class is organised and deliberate but outside the regular school/degree system, which makes it non-formal education. Hence (C).

Answer: (D) Y—(3), R—(1), L—(2), W—(4)

Explanation: Jagannath (Puri) → 3; Rashtriya Sanskrit University (Tirupati) → 1; Kameshwar Singh (Darbhanga) → 2; Gurukul Kangri (Haridwar) → 4. So Y-3, R-1, L-2, W-4. Hence (D).

Answer: (A) Indian Council of Social Science Research

Explanation: ICSSR stands for the Indian Council of Social Science Research, which promotes and funds research in the social sciences. Hence (A).
