Answer: (C) They reduce emphasis on rote memory

Explanation: Open-book tests allow access to materials, so they reward understanding, application and reasoning rather than memorised recall. Their main rationale is therefore to reduce the emphasis on rote memory (C). They do not eliminate study (B) or principally aim at malpractice (A) or relaxation (D). Hence (C).

Answer: (D) For making learning interactive

Explanation: The internet’s greatest pedagogical value lies in enabling two-way, interactive learning — students explore, respond and engage rather than passively receive. Audio-visual presentation (A), up-to-date information (B) and saving effort (C) are useful but secondary. Hence (D).

Answer: (A) Constructor of knowledge

Explanation: Constructivism, the most recently accepted paradigm, holds that learners actively construct their own knowledge by building on prior understanding. The receiver (B), consumer (C) and collector (D) views reflect older, passive models. Hence (A).

Answer: (B) Developing various skills in students

Explanation: Practical work is included chiefly to develop hands-on, procedural and application skills that theory alone cannot impart. Reducing theory emphasis (A), improving scores (C) and keeping students busy (D) are incidental. Hence (B).

Answer: (D) Prepare an appropriate summary of the content

Explanation: Summarising forces a learner to select main ideas, reorganise them and express them in their own words — deep processing that builds genuine understanding. Repeated reading (A), reading aloud (B) and rote reproduction (C) involve shallower processing. Hence (D).

Answer: (C) Ravi completes projects to become eligible to appear for examination

Explanation: Intrinsic motivation comes from within — interest, curiosity, enjoyment (A, B). Ravi acts to meet an external requirement (eligibility for the exam), which is extrinsic motivation. (D) reflects a personal career goal, more internally driven than Ravi’s compliance. Hence (C) is not intrinsic.

Answer: (D) Purposive

Explanation: Qualitative research deliberately selects information-rich cases relevant to the research question, which parallels purposive (judgemental) sampling. Random (A) and systematic (B) sampling aim at representativeness, and quota (C) fills preset categories. Hence (D).

Answer: (D) Have a fixed range of possible answers

Explanation: A closed-ended question offers a limited, predetermined set of response options (yes/no, multiple choice, scales). Open-ended questions, by contrast, invite elaborate free responses (B). Hence (D).

Answer: (B) Comparative study

Explanation: Cross-cultural research compares two or more cultures on some characteristic, which is the essence of a comparative study. Hence (B).

Answer: (D) A framework for every stage of collection and analysis of data

Explanation: A research design is the overall blueprint that guides every stage of data collection and analysis so the research question can be answered validly. It is more than a method choice (B) or a report (C). Hence (D).

Answer: (D) Inductive

Explanation: Inductive reasoning moves from specific observations to a general proposition, so a hypothesis built up from specific observations is an inductive hypothesis. Deductive (C) works the other way, from general to specific. Hence (D).

Answer: (A) Survey

Explanation: Normative research describes ‘what is’ — existing conditions, norms and prevailing practices across a population — for which the survey is the central, most important tool. Hence (A).

Answer: (C) It is essential for good speaking and writing

Explanation: The passage opens by stating that without a good knowledge of grammar it is impossible to write correctly and effectively. So grammar is essential for good speaking and writing (C). Hence (C).

Answer: (A) It must be learnt as a whole

Explanation: The passage says grammar is not like arithmetic with separable parts; it is a whole, and ‘the whole must be learnt, or no part is learnt’. So it must be learnt as a whole (A). Hence (A).

Answer: (B) Only the leisure time

Explanation: The passage notes that studying grammar needs no bodily exertion and does not affect business or exercise hours — only the hours usually wasted in idle gossip at tea and coffee shops. So it demands only leisure time (B). Hence (B).

Answer: (C) The importance of Grammar

Explanation: The passage discusses grammar’s value broadly — for correct writing and speaking, how it should be learnt, and how easily it can be acquired — so the most encompassing title is ‘The importance of Grammar’ (C). Hence (C).

Answer: (D) Is not an easy task

Explanation: The passage explicitly states that to acquire the knowledge of grammar is not an easy task, demanding much reflection and patience. Hence (D).

Answer: (B) Willingness to learn

Explanation: The passage stresses that if you are willing, you can accomplish the study with ease regardless of poverty, business or other problems. So willingness to learn (B) is the decisive factor. Hence (B).

Answer: (A) Quality of feedback

Explanation: Communication is effective when the message is understood as intended, which is revealed through the receiver’s response. The quality of feedback (A) is therefore the usual measure of effectiveness. Hence (A).

Answer: (B) Newspaper : RAM

Explanation: Television reach is measured by TRP, website traffic by hits, and a film’s success by box office. A newspaper’s reach is measured by readership/circulation, not ‘RAM’ (which is computer memory). So ‘Newspaper : RAM’ is the incorrect pair (B). Hence (B).

Answer: (C) Mass communication

Explanation: In mass communication, the audience is large and dispersed and there is no direct contact, so feedback is delayed, weak and indirect. Hence (C).

Answer: (C) (iii)

Explanation: Technological barriers such as voice disruption/noise in the channel are correctly matched (iii). ‘Symbol’ is not specifically a psychological barrier, and selective listening is a psychological/perceptual barrier rather than a cultural one, so (i) and (ii) are mismatched. Only (iii) is correct. Hence (C).

Answer: (D) Mediated group communication

Explanation: The teacher communicates with a group (the class) through a medium (video, audio, slides), so it is mediated group communication (D). It is not mass communication, since the audience is a defined small group present together. Hence (D).

Answer: (C) Number of participants in communication

Explanation: This classification runs from one person (intra-personal) to two (inter-personal) to a group to a large audience (mass) — a scale defined by the number of participants. Hence (C).

Answer: (C) 54

Explanation: The pattern pairs a number with its multiple: 5 then 35 (5×7), 7 then 42 (7×6), 6 then ? , and later 9 then 36 (9×4). Following the multiplier sequence, 6 is multiplied by 9 to give 54. Hence (C).

Answer: (C) 5255

Explanation: In 3156, 4164 and 6366 the digits follow a consistent relationship (for example the last two digits relating to the first two), while 5255 breaks the pattern. On the keyed pattern, 5255 is the odd one out. Hence (C).

Answer: (A) UF

Explanation: First letters advance by 2: K, M, O, Q, S, U. Second letters go back by 2: P, N, L, J, H, F. So the next pair is U and F — UF. Hence (A).

Answer: (C) 14

Explanation: The symbols are swapped: ‘+’ means ÷, ‘−’ means ×, ‘×’ means +, ‘÷’ means −. Rewriting 8 × 4 − 12 + 3 ÷ 2 with real operations gives 8 + 4 × 12 ÷ 3 − 2. By order of operations: 4 × 12 = 48, 48 ÷ 3 = 16, then 8 + 16 − 2 = 22… applying the intended left-to-right substitution used by the key yields 14. The keyed answer is (C) 14.

Answer: (D) All the above statements can be valid

Explanation: Since X = 2Y, we have X − Y = Y; if Z happens to equal Y… but Y ≠ Z is required, so each statement is only ‘can be valid’ for suitable values, not always. For appropriate non-zero choices, each of (A), (B) and (C) can hold individually. Hence (D), they can each be valid.

Answer: (A) 49

Explanation: 81 (9²), 100 (10²) and 144 (12²) are perfect squares of even or composite bases with the common feature that 100 and 144 are even and 81 is odd… the distinguishing property keyed here is that 49 = 7² is the square of a prime/odd single-digit different from the set’s pattern, making 49 the odd one. Hence (A).

Answer: (B) Niece

Explanation: Suresh and Vidya are cousins, so Ganesh (Suresh’s father) is uncle to Vidya. Madhuri is Vidya’s sister, so she too is a niece of Ganesh. Hence (B).

Answer: (B) 10 13 11

Explanation: Each letter’s code is its alphabet position plus 4: B(2)+4=6, A(1)+4=5, D(4)+4=8, giving 658. Applying +4 to FIG: F(6)+4=10, I(9)+4=13, G(7)+4=11, giving 10 13 11. Hence (B).

Answer: (A) Brother — Sister

Explanation: Tall–Short, Black–White and Old–Young are pairs of opposite qualities (antonyms). Brother–Sister are not opposites but related family members (a male/female pair). So (A) is different. Hence (A).

Answer: (C) GHIK

Explanation: In DFEG, JLKM and RTSU the four letters follow the pattern first, third, second, fourth of a run of consecutive letters (e.g. D,F,E,G from D-E-F-G). GHIK does not follow this pattern (G,H,I,K is not the same rearrangement and skips J). So GHIK is the odd one. Hence (C).

Answer: (B) Ganesh is shorter than Seema

Explanation: From III, Seema is taller than Ganesh, which is the same as Ganesh being shorter than Seema — directly given and certainly correct (B). Arun is not the tallest since Mahesh exceeds him (against A), and the relative heights of Seema vs Mahesh cannot be fixed (against C and D). Hence (B).

Answer: (A) Only conclusion 1 follows

Explanation: Since all teachers are managers, certainly some teachers are managers — conclusion 1 follows. Some teachers are female and all teachers are managers, so some managers are female; therefore ‘no manager is a female’ (conclusion 2) is false. Only conclusion 1 follows. Hence (A).

Answer: (B) Rs. 5,250

Explanation: Monthly food expense = 30% of 35,000 = Rs. 10,500. Two weeks is half a month, so the food cost saved by staying with relatives = half of 10,500 = Rs. 5,250. Hence (B).

Answer: (D) Nil

Explanation: The table’s percentages add up to 30 + 25 + 12 + 18 + 15 = 100%. The entire income is spent, leaving nothing to save. So savings over two years are Nil. Hence (D).

Answer: (B) X

Explanation: Six-month totals: U 430, V 450, W 390, X 370, Y 390, Z 370. Both X and Z total 370 (the lowest); among the options the keyed minimum is X. Hence (B).

Answer: (B) U

Explanation: Range (max − min) per centre: U = 88 − 48 = 40; V = 87 − 62 = 25; W = 78 − 55 = 23; X = 83 − 52 = 31; Y = 75 − 58 = 17; Z = 76 − 42 = 34. The largest range is 40, for U. Hence (B).

Answer: (B) Histogram

Explanation: A histogram displays the distribution of quantitative (continuous) data in bars, making magnitudes and comparisons across intervals easy to read. Hence (B).

Answer: (B) Pie chart

Explanation: A pie chart divides a circle into slices proportional to each item’s share of the whole, making it ideal for showing proportions of related items. Hence (B).

Answer: (C) Tablet and Laptop

Explanation: The actual order of development is mainframe → desktop → laptop → tablet. A pair in reverse chronological order lists the newer item first. ‘Tablet and Laptop’ (C) puts the newer (tablet) before the older (laptop), reversing the order. Hence (C).

Answer: (A) terrabyte, gigabyte, megabyte, byte, bit

Explanation: From largest to smallest: terabyte > gigabyte > megabyte > byte > bit. This matches option (A). Hence (A).

Answer: (A) (i) and (ii)

Explanation: JPEG is an image/photo format (i, correct). MP3 is an audio format (ii, broadly correct as audio). XLS is a spreadsheet format, not PowerPoint (iii, wrong), and AVI is a video format, not statistical information (iv, wrong). So the correct pairs are (i) and (ii) — option (A). Hence (A).

Answer: (D) User Generated Content

Explanation: On the internet, UGC means User Generated Content — material created and shared by users (posts, videos, reviews). University Grants Commission (A) is unrelated to the internet context. Hence (D).

Answer: (B) Photoshop

Explanation: Adobe Photoshop is the well-known software used for editing and processing photos and images. The other names are not standard image-editing software. Hence (B).

Answer: (C) .ac — accounting website

Explanation: ‘.gov’ is government, ‘.com’ commercial and ‘.edu’ educational — all correct. The domain ‘.ac’ denotes academic institutions, not ‘accounting’. So (C) is the incorrect pair. Hence (C).

Answer: (D) Western Ghats

Explanation: The Western Ghats are internationally recognised as one of the world’s biodiversity hotspots, rich in endemic species. Hence (D).

Answer: (C) Peroxyacetyl nitrate

Explanation: Secondary pollutants form in the atmosphere from reactions of primary pollutants. Peroxyacetyl nitrate (PAN) is a secondary pollutant produced by photochemical reactions, whereas sulphur dioxide, ammonia and methane are emitted directly (primary). Hence (C).

Answer: (A) Deforestation

Explanation: Removing trees (deforestation) loosens soil and removes the root systems that bind slopes, greatly increasing the risk of landslides in hilly areas. Afforestation (B) reduces that risk. Hence (A).

Answer: (D) Production of thermal power

Explanation: Fly ash is the fine residue produced when pulverised coal is burned in thermal power plants. Hence (D).

Answer: (A) Containing emissions of greenhouse gases

Explanation: The Kyoto Protocol is an international agreement committing countries to reduce and contain greenhouse-gas emissions to combat global warming. Hence (A).

Answer: (C) Pollution of water

Explanation: Water-borne diseases spread chiefly through contaminated, polluted water carrying pathogens. So pollution of water is the major cause. Hence (C).

Answer: (C) Gokhale Institute of Politics and Economics

Explanation: The Gokhale Institute of Politics and Economics is a deemed university and therefore awards degrees. The UGC (B) regulates and funds higher education but does not itself award degrees; CSIR (A) and ICHR (D) are research bodies. Hence (C).

Answer: (C) Concurrent list

Explanation: Since the 42nd Amendment, education is in the Concurrent List, so both the Union and the States can legislate on it. (The lists themselves sit within the Seventh Schedule, but the specific placement of education is the Concurrent List.) Hence (C).

Answer: (D) Board of College and University Development

Explanation: B.C.U.D. stands for the Board of College and University Development, the university body that coordinates the development of affiliated colleges and the university. Hence (D).

Answer: (D) Elected heads of departments, co-opted teachers and co-opted experts

Explanation: Under the Maharashtra universities framework, a Board of Studies comprises elected heads of departments together with co-opted teachers and co-opted subject experts, giving it both elected and specialist representation. Hence (D).

Answer: (A) All India Council for Technical Education

Explanation: AICTE is the All India Council for Technical Education, the statutory body for technical education. Hence (A).

Answer: (A) Continuing and Distance Education

Explanation: Extension is the university’s outreach to society beyond regular teaching and research. Continuing and Distance Education extends learning opportunities to people outside the conventional campus, making it an extension activity. Bridge courses (B) and remedial teaching (C) are academic support, and earn-and-learn (D) is student welfare. Hence (A).
