Answer: (B) Project method

Explanation: The project method engages students in applying what they have learnt to real, practical tasks, connecting course content to day-to-day life. Demonstration (A) shows a process, field visits (C) give exposure, and inquiry (D) promotes investigation, but the project method most directly achieves application in everyday life. Hence (B).

Answer: (A) formative evaluation

Explanation: Formative evaluation takes place during the teaching-learning process, giving ongoing feedback that lets the teacher monitor progress and adjust instruction. Summative evaluation (B) comes at the end and cannot guide mid-course changes. Hence (A).

Answer: (B) Evaluation

Explanation: Asking a student to ‘prove’ or judge whether a claim is true requires weighing evidence and making a reasoned judgement, which is the evaluation level of Bloom’s taxonomy. Hence (B).

Answer: (C) Attractive personality

Explanation: Good teaching depends on relating well to students (A), communicating clearly (B) and knowing suitable methods (D). An attractive personality (C) may help rapport but is not essential to effective teaching. Hence (C).

Answer: (C) make them capable of helping themselves

Explanation: The ultimate aim of guidance is to develop self-reliance, so that students can understand and solve their own problems independently. Helping them see shortcomings (A), change behaviour (B) or giving direction (D) are steps toward this larger goal of self-help. Hence (C).

Answer: (C) explaining, in the beginning, the purpose of teaching a unit

Explanation: When learners understand why a topic matters and what they will gain, their intrinsic motivation to learn rises. Punishment (A) discourages, difficult questions (B) can demotivate, and aids (D) help attention but not purpose. Explaining the purpose (C) best builds motivation. Hence (C).

Answer: (C) interest of the researcher

Explanation: A research problem is primarily chosen based on the researcher’s genuine interest, which sustains the motivation and persistence needed to carry the study through. Relevance, funds and literature are important considerations but secondary to the driving interest. Hence (C).

Answer: (C) A research article published in a standard journal

Explanation: A primary source presents original, first-hand research directly from those who conducted it, such as a research article in a standard journal. Reviews (A), textbooks (B) and treatises (D) discuss or compile others’ work and are secondary sources. Hence (C).

Answer: (C) Longitudinal

Explanation: Studying change in the same variable over a long period (here population across decades) is a longitudinal study. A cross-sectional study (D) examines data at a single point in time. Hence (C).

Answer: (A) normative

Explanation: Normative (descriptive/survey) studies aim to describe existing conditions or ‘what is’, and can proceed without a formal hypothesis. Experimental and correlational studies typically require hypotheses to test relationships. Hence (A).

Answer: (B) Stratified sampling

Explanation: Stratified sampling divides the population into strata and selects randomly within each, so every unit has a known, non-zero probability of selection — a probability method. Judgement (A), quota (C) and convenience (D) sampling are non-probability methods. Hence (B).

Answer: (A) real life situations

Explanation: A field study investigates phenomena in their natural, real-life settings rather than under controlled laboratory conditions. Hence (A).

Answer: (B) have ill will for his enemy

Explanation: The passage says non-violence is complete absence of ill-will against all that lives; a truly non-violent person wishes his wrong-doer well and harbours no ill will. So he would not even have ill will for his enemy (B). Hence (B).

Answer: (D) all forms of life

Explanation: The passage states that non-violence embraces even sub-human life, not excluding noxious insects or beasts — it is goodwill towards all life. So it concerns all forms of life (D). Hence (D).

Answer: (C) All living beings have their proper place in the universe

Explanation: The passage says that if we knew the mind of the Creator we should find every creature’s proper place in His creation — i.e. all living beings have their proper place (C). Non-violence is love for all life (not only those we know), and it is an active, not passive, state, so B and D are wrong. Hence (C).

Answer: (A) beastly

Explanation: The passage states that in our present state we are partly men and partly beasts, delivering blow for blow. So man is partly beastly in behaviour (A). Hence (A).

Answer: (B) Love

Explanation: The passage concludes that non-violence in its active form is goodwill towards all life — ‘It is pure Love.’ Hence (B).

Answer: (D) The spirit of non-violence

Explanation: The passage explores the inner nature and meaning of non-violence — as innocence, goodwill and love — rather than its advantages or politics. The unifying theme is the spirit of non-violence (D). Hence (D).

Answer: (A) Verbal signs or signals are more in terms of quantum and variety

Explanation: In face-to-face communication, non-verbal signals (expressions, tone, posture, gestures) actually outnumber and out-vary verbal ones, so saying verbal signals are greater in quantum and variety (A) is incorrect. The others are true: non-verbal cues are hard to control and largely involuntary, and are trusted more when meaning is unclear. Hence (A).

Answer: (C) Interpersonal Communication

Explanation: Interpersonal (one-to-one, face-to-face) communication allows immediate, direct, two-way feedback, so the potential for quick and reliable feedback is greatest. Mass and group communication have slower, weaker feedback. Hence (C).

Answer: (D) Radio — ROD

Explanation: Newspaper reach is measured by circulation, cinema by box office, and television by TVT/TRP ratings. Radio performance is measured by listenership ratings, not ‘ROD’, which is not a real indicator. So Radio — ROD is the incorrect pair. Hence (D).

Answer: (B) Frequency Modulation

Explanation: FM stands for Frequency Modulation, the broadcasting technique in which the carrier wave’s frequency is varied to encode the signal. Hence (B).

Answer: (B) give more communicative power to teacher for control

Explanation: When all students face the teacher, communication flows mainly from teacher to students, concentrating communicative power with the teacher and giving control. It limits student-to-student interaction and multidirectional exchange. Hence (B).

Answer: (A) Body language of students

Explanation: A teacher can read students’ body language — expressions, posture, attentiveness — instantly and continuously during class, making it the quickest, easiest source of feedback. Questions, notes and assignments come later. Hence (A).

Answer: (B) The sequence is bounded above by 0.99

Explanation: The terms n/(n+1) increase toward 1, so for large n they exceed 0.99 (e.g. 100/101 ≈ 0.990). Hence the sequence is NOT bounded above by 0.99, making (B) the untrue statement. It is strictly increasing, bounded between 1/2 and 1, and jumps from 3/4 (=0.75) directly to 4/5 (=0.8) with nothing between consecutive terms there. Hence (B).

Answer: (C) Thinking

Explanation: The four language (linguistic) skills are listening, speaking, reading and writing. Thinking is a cognitive process, not one of the linguistic skills. Hence (C).

Answer: (A) Between any two numbers in X, there is at least one number in X

Explanation: Statement (A) — that between any two members there is at least one member — is the weakest ‘density’ condition, yet it actually implies the others: if you can always find one number between two, you can repeat the process to find two, then infinitely many. The question asks which statement, taken alone, does not need to be deduced from the stronger ones; (A) is the base condition from which the rest follow, so it is the odd one that the others do not yield. Hence (A). (This is a subtle logic item; verify against the official key.)

Answer: (A) 5

Explanation: Every handshake involves two hands, so counting hands ‘with multiplicity’ always gives an even total. An odd value such as 5 is therefore impossible. Hence (A).

Answer: (C) at the most two points

Explanation: Two distinct circles can meet in at most two points — they may touch at one point (tangent) or cross at two, but never more. ‘At the most two points’ (C) is the precise general statement. Hence (C).

Answer: (A) 108136

Explanation: Each letter is coded by its alphabet position with A = 0 (so B = 1, C = 2, …): P=15, R=17, I=8, N=13, C=2, E=4, giving 151781324. Applying the same to KING: K=10, I=8, N=13, G=6, giving 108136. Hence (A).

Answer: (B) Only 2

Explanation: Since all bowlers of my team are wicket takers, and Varun is not a wicket-taking bowler, Varun cannot be a bowler of my team — conclusion 2 follows. Nothing tells us he is a spin bowler, so conclusion 1 does not follow. Hence (B).

Answer: (C) Both 1 and 2

Explanation: All apples are mangoes and all mangoes are bananas, so all apples are bananas — conclusion 1 follows. Since all mangoes are bananas, those mangoes are bananas, so some bananas are mangoes — conclusion 2 also follows. Hence (C).

Answer: (B) 21191017

Explanation: Each letter is coded by its alphabet position plus 1: F(6+1)=7, R(18+1)=19, O(15+1)=16, G(7+1)=8, giving 719168. Applying to TRIP: T(20+1)=21, R(18+1)=19, I(9+1)=10, P(16+1)=17, giving 21191017. Hence (B).

Answer: (C) NML

Explanation: In FEG, TSU and RQS the letters follow the pattern (−1, +2) from the first letter: F→E→G, T→S→U, R→Q→S. In NML the pattern is (−1, −1): N→M→L, which is different. So NML is the odd one out. Hence (C).

Answer: (B) P

Explanation: Placing them around the table (clockwise = to the right, facing centre): Q, T, R, S, P. This satisfies all clues — P is on Q’s left, T on Q’s right, S on R’s right, and neither P-T nor S-Q are neighbours. Going right (clockwise) from S is P. Hence (B).

Answer: (A) MON

Explanation: Each group has the pattern (start)(start+2)(start+1). The starting letters jump by 4: E, I, M, Q, U. The missing group starts at M: M, O (M+2), N (M+1) — MON. Hence (A).

Answer: (C) 6669

Explanation: Post-graduate students in N and O = (15% + 12%) of 24,700 = 27% of 24,700 = 6,669. Hence (C).

Answer: (D) 8372

Explanation: Graduate in Q = 18% of 27,300 = 4,914; Post-graduate in Q = 14% of 24,700 = 3,458. Total = 4,914 + 3,458 = 8,372. Hence (D).

Answer: (D) 19 : 14

Explanation: Post-graduate in R = 21% of 24,700 = 5,187; Graduate in R = 14% of 27,300 = 3,822. The ratio 5,187 : 3,822 simplifies to about 1.357, i.e. 19 : 14. Hence (D).

Answer: (D) 19 : 13

Explanation: Post-graduate in R = 21% of 24,700 = 5,187; Graduate in P = 13% of 27,300 = 3,549. The ratio 5,187 : 3,549 simplifies to about 1.4615, i.e. 19 : 13. Hence (D).

Answer: (A) 6 million acres

Explanation: Jowar is 5% and rice is 20% of the total — rice occupies four times the jowar area. So rice = 4 × 1.5 = 6 million acres. Hence (A).

Answer: (B) 3 : 1

Explanation: Wheat area is 20% and barley area is 10% (wheat area is twice barley’s). Yield per acre = production ÷ area. Wheat : barley yield per acre = (6 ÷ 20) : (1 ÷ 10) = 0.3 : 0.1 = 3 : 1. Hence (B).

Answer: (C) Hotmail, Google, Facebook, Whatsapp

Explanation: By launch year: Hotmail (1996), Google (1998), Facebook (2004), WhatsApp (2009). So the order is Hotmail → Google → Facebook → WhatsApp. Hence (C).

Answer: (A) MS-Office

Explanation: Windows, Android, Linux and Unix are all operating systems. MS-Office is an application software suite, not an operating system, so it is the odd one out on the basis of function. Hence (A).

Answer: (D) Portable Document File

Explanation: PDF stands for Portable Document Format (Portable Document File), a format that preserves a document’s layout across devices. Among the options, (D) is the intended answer. Hence (D).

Answer: (C) Drop box

Explanation: Dropbox is a cloud-based file storage and synchronisation service. The Play Store is an app marketplace, and ‘Cloud stick’ is not a standard cloud service. Hence (C).

Answer: (B) Content on these facilities is generated mostly by users

Explanation: Web 2.0 is defined by user-generated content and interactivity — users create and share the content (posts, videos, reviews). Communication is two-way (not one-way), so (A) is wrong; (C) and (D) are not defining features. Hence (B).

Answer: (A) Ubuntu — Operating System

Explanation: Ubuntu is indeed an operating system (a Linux distribution). Excel is a spreadsheet (not word processing), AVI is a video format (not a transfer protocol), and HDD is a hard disk drive (not cloud storage). Hence (A).

Answer: (B) Making bricks

Explanation: Fly ash from thermal power plants is widely used to manufacture fly-ash bricks, a productive reuse of the waste. Hence (B).

Answer: (B) 5th June

Explanation: World Environment Day is observed every year on 5th June. Hence (B).

Answer: (A) Environment (Protection) Act

Explanation: The Environment (Protection) Act, 1986 is the umbrella legislation empowering citizens and the government to act against violations of environmental norms. Hence (A).

Answer: (B) Carbon dioxide

Explanation: Carbon dioxide is the principal greenhouse gas responsible for global warming, trapping outgoing heat in the atmosphere. Hence (B).

Answer: (D) Coal

Explanation: Solar, tidal and geothermal are renewable, non-conventional energy sources. Coal is a conventional fossil fuel. Hence (D).

Answer: (D) Tiger

Explanation: The tiger is an apex (top) carnivore/predator. The buffalo is a herbivore, while birds and snakes occupy lower trophic levels. Hence (D).

Answer: (B) Shodhaganga

Explanation: Shodhganga is the digital repository of Indian doctoral theses and dissertations, maintained by INFLIBNET. Hence (B).

Answer: (B) MHRD

Explanation: Policy for higher education in India is formulated by the Ministry of Human Resource Development (MHRD, now the Ministry of Education). The UGC coordinates and maintains standards, and NAAC accredits, but policy-making rests with the ministry. Hence (B).

Answer: (B) NAAC

Explanation: The National Assessment and Accreditation Council (NAAC) is responsible for assessing and accrediting higher education institutions in India. Hence (B).

Answer: (C) Excellent

Explanation: In the UGC’s 10-point CBCS grading system, ‘O’ is Outstanding and ‘A+’ denotes Excellent. Hence (C).

Answer: (A) Credit

Explanation: The credit is the unit used to measure the volume of course work (based on instructional hours). Hence (A).

Answer: (A) Dr. B.R. Ambedkar Open University

Explanation: India’s first open university was Dr. B.R. Ambedkar Open University, established in Andhra Pradesh in 1982 (originally Andhra Pradesh Open University). IGNOU came later, in 1985. Hence (A).
