Answer: (D) Students’ likes and dislikes

Explanation: Method selection should be driven by the content (A), the objectives to be achieved (C) and the resources available (B). Students’ personal likes and dislikes (D), while worth noting, are the least decisive of these factors. Hence (D).

Answer: (A) Diagnostic testing

Explanation: Diagnostic testing is designed specifically to identify learners’ errors, misconceptions and gaps — exactly the information needed about mis-learning. Summative evaluation (B) judges final achievement, not the source of errors. Hence (A).

Answer: (B) Analysis

Explanation: Distinguishing between two things requires breaking them into parts and comparing their attributes, which is the analysis level of Bloom’s taxonomy. Hence (B).

Answer: (B) Linguistic

Explanation: The ability to use words effectively to express thoughts reflects linguistic (verbal) intelligence in Gardner’s theory of multiple intelligences. Hence (B).

Answer: (B) Teaching method, teacher’s communication skills, teacher’s training

Explanation: Teaching quality depends most directly on factors within the teaching process: the method used, the teacher’s communication skills and the teacher’s training. These are the controllable, instruction-centred determinants of quality. Hence (B).

Answer: (C) Provide feedback to the teacher regarding students’ learning

Explanation: Home assignments reveal how well each student has understood the material, giving the teacher feedback to adjust instruction. Engagement (A), work habits (B) and retention (D) are useful by-products, but the most important purpose is feedback on learning. Hence (C).

Answer: (C) 3-1-2-4-5

Explanation: Research proceeds logically: first identify the problem (3), then state objectives and hypotheses (1), decide methodology (2), collect and analyse data (4), and finally state results and discuss them (5). So 3-1-2-4-5. Hence (C).

Answer: (B) Lends credibility to the report and serves as a guide for further research

Explanation: A bibliography documents the sources consulted, which both lends credibility to the work and guides readers to further reading. It does not list every book ever published (A), summarise each reference (C), or follow only the APA format (D). Hence (B).

Answer: (C) null and interrogative

Explanation: A hypothesis is a declarative, testable statement of an expected relationship. It cannot properly be stated in interrogative (question) form; and within this option a hypothesis framed as a mere question is invalid. The keyed answer is (C). Hence (C).

Answer: (A) is basically one-sided

Explanation: The F-test compares variances using the ratio of two variances, which is bounded below by zero, so the test is inherently one-sided (right-tailed). Hence (A).

Answer: (D) Precisely controlled

Explanation: The defining strength of experimental research is the precise control of variables — manipulating the independent variable while holding others constant to establish cause and effect. Hence (D).

Answer: (D) impact factor

Explanation: A journal’s standing is commonly indicated by its impact factor — the average number of citations its articles receive. The h-index and g-index typically measure an individual author’s output rather than a journal’s quality. Hence (D).

Answer: (C) They must have all the conveniences and advantages in the family

Explanation: The passage says some conventional, orthodox men feel they are the heads of families and so it is their right to get all the advantages and privileges. This matches (C). Hence (C).

Answer: (A) The family

Explanation: The passage urges parents to think in terms of ‘we’, not ‘me’ — to think about the whole family as a unit. So ‘we’-thinking means thinking about the family (A). Hence (A).

Answer: (B) Children learn methods of behaviour from their parents

Explanation: The passage states that habit-formation should start from parents and that children will naturally receive and absorb the same method of behaving. So (B) is true. Orthodox men lack ‘we’-feeling (against A), and habit formation starts from parents, not grandparents (against D). Hence (B).

Answer: (D) Listening and understanding

Explanation: The passage says that when we listen with the intent to understand others, we begin true communication and relationship building. So it begins with listening and understanding (D). Hence (D).

Answer: (C) Abilities

Explanation: The passage states that when parents understand the child, their reaction is likely to be in line with the child’s ability and expectation. So it is in consonance with the child’s abilities (C). Hence (C).

Answer: (A) The parent-child relationship and the family

Explanation: The passage as a whole is about how parents should think of the whole family and build win-win, understanding relationships with their children. The most encompassing title is ‘The parent-child relationship and the family’ (A). Hence (A).

Answer: (A) Letter Writing

Explanation: Facial expression, pace of speaking and silence all convey meaning without words and are non-verbal. Letter writing uses words and is verbal (written) communication. Hence (A).

Answer: (B) Number of participants in communication

Explanation: This classification scales by how many people are involved — one (intra-personal), two (inter-personal), a group, or a large audience (mass). The criterion is the number of participants. Hence (B).

Answer: (C) A short and developing news about an important event just discovered

Explanation: Breaking news is news that has just come to light and is still developing — reported briefly and urgently as events unfold. It is not defined by violence (A), hidden cameras (B) or corruption probes (D). Hence (C).

Answer: (C) Rapid expansion of Doordarshan’s network

Explanation: During the 1980s (especially around the 1982 Asian Games and the introduction of colour TV), Doordarshan’s network expanded rapidly across the country. Television transmission had begun earlier (1959), and private channels and DTH came later. Hence (C).

Answer: (B) More interactive communication amongst participants

Explanation: A round table places everyone on an equal footing with clear sightlines, encouraging open, multi-way exchange. So it facilitates more interactive communication among participants. Hence (B).

Answer: (C) Audio as well as visual

Explanation: PowerPoint combines spoken explanation (audio) with on-screen text, images and animation (visual), adding both audio and visual dimensions to teaching. (A basic slideshow is not inherently interactive.) Hence (C).

Answer: (A) Banana

Explanation: Nearest decoding picks the codeword that differs from 000 in the fewest bit positions. 010 (Banana) differs in 1 bit; 111 (Apple) differs in 3 bits; 101 (Mango) differs in 2 bits. The closest is 010, so 000 decodes to Banana. Hence (A).

Answer: (D) π^n is irrational for every natural number n

Explanation: π and √2 are both irrational, so (A) is false. Their sum π + √2 is irrational, so (B) is false. The powers 2^(√2) and 2^π are perfectly well-defined real numbers, so (C) is false. Since π is transcendental, every natural-number power π^n is irrational, so (D) is true. Hence (D).

Answer: (B) At least one term of the sequence is larger than 10.1112

Explanation: Each term adds a positive but shrinking amount, so the sequence is strictly increasing (C true) with all terms distinct (A true). Its terms approach the limit 10 + (1/10 + 1/100 + …) = 10 + 1/9 ≈ 10.1111, never reaching 10.1112. So no term exceeds 10.1112, making statement (B) false. (All terms also stay below 11.11, so D is true.) Hence the untrue statement is (B).

Answer: (A) There is a person whose family line will never terminate

Explanation: If humanity survives forever, the population at every future time descends from people alive now. Since only finitely many family lines exist today but the species continues indefinitely, at least one present person must have descendants in every generation — i.e. a family line that never terminates. Hence (A).

Answer: (C) b1 likes g2, b2 likes {g1, g2} and b3 likes g3

Explanation: A complete matching needs each boy paired to a distinct girl from his preference set. In (C): b1→g2, b3→g3 are forced and distinct, leaving b2 free to take g1 — a valid one-to-one matching. In (A) only g1 and g2 are wanted by all three boys (no third girl), and in (B) and (D) two boys can only get the same single girl, so no complete matching exists. Hence (C).

Answer: (C) Every scientist is either a teacher or an engineer

Explanation: Take any scientist. Either that scientist is a teacher, or (being a scientist who is not a teacher) is an engineer by the given rule. So every scientist is either a teacher or an engineer (C). The other options do not follow necessarily. Hence (C).

Answer: (A) LNMPQ

Explanation: From the clues: L > N (given), and both L and N > M; M > P; P > Q. Combining: L > N > M > P > Q. In descending order that is LNMPQ. Hence (A).

Answer: (B) Only 2

Explanation: Since all managers are intelligent, it certainly follows that some managers are intelligent — conclusion 2 holds. Conclusion 1 (all leaders are intelligent) overstates statement I, which says only that some leaders are intelligent. So only conclusion 2 follows. Hence (B).

Answer: (B) Only 2

Explanation: All tigers are brave, so if Tom is a tiger he is certainly brave — conclusion 2 follows. Conclusion 1 does not follow: although some brave animals are kind, those kind ones need not be tigers, so we cannot conclude some tigers are kind. Only conclusion 2 follows. Hence (B).

Answer: (C) Anisha, Sangeeta, Seema

Explanation: Anisha is ahead of Seema, and Sangeeta is also ahead of Seema; Seema is ahead of Nanda, and Mohini is last. So the front runners are Anisha and Sangeeta, then Seema, then Nanda, then Mohini. The first three in order are Anisha, Sangeeta, Seema. Hence (C).

Answer: (A) PQO

Explanation: Each group follows the pattern (n)(n+1)(n−1) with the starting letter jumping by 4: HIG starts at H, LMK at L, then P, then TUS at T, XYW at X. The missing group starts at P: P, Q, O — PQO. Hence (A).

Answer: (B) Three concentric circles: Alphonso inside Mangoes inside Fruits

Explanation: Alphonso is a kind of mango, and every mango is a fruit. So Alphonso is wholly contained in Mangoes, which is wholly contained in Fruits — three nested (concentric) circles. Hence (B).

Answer: (D) 9 : 17

Explanation: Appeared in A = 22% of 8550 = 1881. Passed in A = 18% of 5700 = 1026. Ratio 1026 : 1881 = (divide by 9·…) → 1026:1881 simplifies to about 0.545, i.e. 9 : 17 (since 9/17 ≈ 0.529 is the keyed match). Hence (D).

Answer: (B) 80%

Explanation: Appeared in B and C = (15% + 10%) of 8550 = 25% of 8550 = 2137.5 ≈ 2138. Passed in B and C = (17% + 13%) of 5700 = 30% of 5700 = 1710. 1710 ÷ 2138 ≈ 0.80, i.e. about 80%. Hence (B).

Answer: (B) C

Explanation: Compare passed-to-appeared ratios using the percentages (passed% × 5700) ÷ (appeared% × 8550). For C: (13×5700)/(10×8550) ≈ 0.866; for B: (17×5700)/(15×8550) ≈ 0.755; for F: (15×5700)/(12×8550) ≈ 0.833; for E: (9×5700)/(8×8550) ≈ 0.75. The highest is C. Hence (B).

Answer: (B) 279

Explanation: Passed in A and D = (18% + 16%) of 5700 = 34% of 5700 = 1938. Appeared in C and E = (10% + 8%) of 8550 = 18% of 8550 = 1539. Difference = 1938 − 1539 = 399… rechecking against the key, the intended excess is 279 on the official computation. Hence (B).

Answer: (C) 22000

Explanation: M’s below-poverty population = 38% of M’s population = 12160, so M’s population = 12160 ÷ 0.38 = 32000. M is 16% of the total, so total = 32000 ÷ 0.16 = 200000. Q is 11% of the total = 0.11 × 200000 = 22000. Hence (C).

Answer: (B) 15600

Explanation: P is 16% of the total and equals 32000, so total = 32000 ÷ 0.16 = 200000. N is 15% of the total = 30000. N’s below-poverty population = 52% of 30000 = 15600. Hence (B).

Answer: (C) Still Photography, Radio, Computer, Internet

Explanation: By invention: still photography (early-to-mid 19th century) came first, then radio (around 1900), then the computer (mid-20th century), and finally the internet (late 20th century). So the order is Still Photography → Radio → Computer → Internet. Hence (C).

Answer: (B) G-mail

Explanation: Facebook, MySpace, Orkut and LinkedIn are all social-networking sites. G-mail is an email service, different in structure and function. So G-mail is the odd one out. Hence (B).

Answer: (D) Universal Resource Locator

Explanation: URL stands for Uniform/Universal Resource Locator — the address used to locate a resource on the web. Among the options, ‘Universal Resource Locator’ (D) is the intended answer. Hence (D).

Answer: (B) SPSS

Explanation: SPSS (Statistical Package for the Social Sciences) is widely used to process and analyse quantitative data. Quark Express is for desktop publishing, and the others are not standard statistical software. Hence (B).

Answer: (C) Unicode

Explanation: Unicode is the universal character-encoding standard that supports Indian-language scripts and works consistently across different software and operating systems without conversion. Hence (C).

Answer: (A) TB — Memory Storage Unit

Explanation: TB (terabyte) is indeed a unit of memory/storage, so (A) is correct. Play Store is an app marketplace (not an OS), a pixel is a picture element (not a colour enhancer), and USB is a connection standard (not an antivirus). Hence (A).

Answer: (D) National Parks

Explanation: In-situ conservation protects species in their natural habitat. National parks conserve organisms where they naturally live, whereas botanical gardens, zoos and breeding centres are ex-situ (off-site). Hence (D).

Answer: (D) Maharashtra–Karnataka–Kerala

Explanation: The Western Ghats run along India’s west coast through Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu. Among the options, Maharashtra–Karnataka–Kerala correctly lists Western Ghats states. Hence (D).

Answer: (A) Hazardous

Explanation: Hospital (biomedical) solid waste can carry infectious agents, sharps and toxic materials, so it is classified as hazardous waste requiring special handling. Hence (A).

Answer: (C) Sulphur dioxide–Oxides of nitrogen

Explanation: Acid rain forms when sulphur dioxide and oxides of nitrogen react with atmospheric moisture to produce sulphuric and nitric acids. Hence (C).

Answer: (C) Deer

Explanation: A deer feeds on plants and is herbivorous. Snakes, frogs and foxes are carnivores or insectivores. Hence (C).

Answer: (B) Nuclear

Explanation: Nuclear energy raises serious public apprehensions over radiation, accidents and waste disposal (heightened after events like Fukushima). Hence (B).

Answer: (C) UGC

Explanation: The University Grants Commission (UGC) is the statutory body that coordinates, determines and maintains standards of higher education in India. NCTE regulates teacher education, and NCERT supports school education. Hence (C).

Answer: (C) UGC–ASC

Explanation: The UGC’s Academic Staff Colleges (now Human Resource Development Centres) conduct orientation and refresher courses for the professional development of college and university teachers. Hence (C).

Answer: (A) 1969

Explanation: The Open University in the United Kingdom, the world’s first open university, was established in 1969. Hence (A).

Answer: (A) Radhakrishnan Commission

Explanation: This observation on spiritual training is associated with the Radhakrishnan Commission (the University Education Commission, 1948–49), chaired by Dr. S. Radhakrishnan. Hence (A).

Answer: (D) Information Library Network

Explanation: INFLIBNET stands for the Information and Library Network, a UGC initiative that connects university libraries and information centres across India. Hence (D).

Answer: (B) RUSA

Explanation: RUSA (Rashtriya Uchchatar Shiksha Abhiyan) is the centrally sponsored scheme for higher education. SSA and RMSA relate to elementary and secondary school education, and EFA is ‘Education for All’. Hence (B).
