25 questions with answers and explanations

Q1.Science & TechnologyEasy

On which zone of Indian Railways was KAVACH Version 4.0 commissioned for the first time?

  1. A.Northern Railway
  2. B.South Central Railway
  3. C.Western Railway
  4. D.East Coast Railway
Show answer

Correct answer: B. South Central Railway

Explanation

The correct answer is South Central Railway. The Ministry of Railways said that Version 4.0 of the train protection system was put into service for the first time on this zone, on the Malkajgiri-Kamareddi section of the Hyderabad Division. The zone was the natural choice because the previous edition, Version 3.2, was already working there across a long stretch of route, and the operating experience gathered from it shaped the improvements built into the newer version. Northern Railway is wrong, because the release names no such commissioning on that zone. Western Railway is wrong for the same reason; the announcement is confined to the southern zone named in it. East Coast Railway is also wrong, as the section upgraded lies in the Hyderabad Division, which belongs to South Central Railway and not to the eastern coastal zone. Candidates should tie the version number, the zone, the division and the section together, since a question may name any one of them.

Q2.Government SchemesEasy

What is the annual health cover available to a beneficiary under Ayushman Bharat, as cited by the Prime Minister on its eighth anniversary?

  1. A.Rs 1 lakh
  2. B.Rs 3 lakh
  3. C.Rs 5 lakh
  4. D.Rs 10 lakh
Show answer

Correct answer: C. Rs 5 lakh

Explanation

The correct answer is Rs 5 lakh. In his anniversary message the Prime Minister said that more than sixty crore beneficiaries now have access to an annual health cover of this amount, and that the reach of the cover is what makes the initiative the largest healthcare scheme in the world. Rs 1 lakh is wrong; no such figure appears in the message, and a cover that small would not carry a family through a serious hospital admission, which is the burden the scheme was designed to lift. Rs 3 lakh is wrong for the same reason and is offered only as a plausible-looking lower figure. Rs 10 lakh is wrong because the cover named is half that amount, though aspirants sometimes confuse it with other insurance products. The safest way to hold this is to remember the pair together: the cover amount on one side and the beneficiary count on the other, because examiners frequently ask for one and supply the other.

Q3.EconomyMedium

Who moderated the panel discussion 'Industry Associations Advancing India's National Agenda' at SEMICON India 2026?

  1. A.The Chief Executive Officer of NITI Aayog
  2. B.Amitesh Kumar Sinha, CEO of the India Semiconductor Mission
  3. C.The Governor of the Reserve Bank of India
  4. D.The Chairman of ISRO
Show answer

Correct answer: B. Amitesh Kumar Sinha, CEO of the India Semiconductor Mission

Explanation

The correct answer is Amitesh Kumar Sinha, Chief Executive Officer of the India Semiconductor Mission. The backgrounder names him as the moderator of the session, which brought senior representatives of the leading industry associations together to discuss how deeper cooperation could speed up the country's semiconductor and electronics plans. The Chief Executive Officer of NITI Aayog is wrong, as that office is not connected with this session in the release. The Governor of the Reserve Bank of India is wrong because the discussion concerned manufacturing and industry coordination rather than monetary policy, and no central bank official is mentioned. The Chairman of ISRO is wrong for the same reason; the space agency has no role in the panel described. Aspirants should remember the mission's name along with the office, because questions often ask which body the moderator headed rather than his name, and the India Semiconductor Mission is itself a frequently tested institution.

Q4.NationalEasy

How many digits does an IMEI number contain?

  1. A.Ten digits
  2. B.Twelve digits
  3. C.Fifteen digits
  4. D.Eighteen digits
Show answer

Correct answer: C. Fifteen digits

Explanation

The correct answer is fifteen digits. The International Mobile Equipment Identity is described as a unique number of that length which identifies a mobile device on a telecom network, and the first eight of those digits make up the Type Allocation Code that identifies the model or type of the handset. Ten digits is wrong; that is the length of a mobile telephone number in India and the two are often confused, but a telephone number belongs to the connection while this number belongs to the device. Twelve digits is wrong as well and matches no identifier described in the backgrounder. Eighteen digits is wrong because it overstates the length, and no identifier of that size is named. Candidates should also remember the way to read one off a handset, which is by dialling the short code given in the release, and that a dual-SIM phone normally carries two such numbers, one for each slot.

Q5.Science & TechnologyMedium

At which event was Prasar Bharati's WAVES OTT platform launched?

  1. A.The 55th International Film Festival of India in Goa
  2. B.The first WAVES Summit in Mumbai
  3. C.The India International Trade Fair in New Delhi
  4. D.The Kolkata International Film Festival
Show answer

Correct answer: A. The 55th International Film Festival of India in Goa

Explanation

The correct answer is the 55th International Film Festival of India in Goa, where the platform was unveiled in November as the public broadcaster's public-service streaming service. The first WAVES Summit in Mumbai is wrong, and is the most tempting distractor because the summit carries the same name: it was held later, in May of the following year, and the streaming platform already existed by then. The India International Trade Fair is wrong, as the backgrounder connects the launch to a film festival and not to a trade exhibition. The Kolkata International Film Festival is wrong as well; although it is also a film festival, the release names the national festival held in Goa and gives its edition number. The safe way to carry this is as a set: the broadcaster, the festival with its edition number, the venue state and the launch date, since a question may supply any one of them and ask for another.

Q6.NationalMedium

Which department organises the Special Campaign in which the Ministry of Home Affairs is taking part?

  1. A.Department of Administrative Reforms and Public Grievances
  2. B.Department of Personnel and Training
  3. C.Cabinet Secretariat
  4. D.Ministry of Panchayati Raj
Show answer

Correct answer: A. Department of Administrative Reforms and Public Grievances

Explanation

The correct answer is the Department of Administrative Reforms and Public Grievances, usually written as DARPG, which the release names as the organiser of the drive. The Ministry of Home Affairs is a participant, not the organiser, and its role is to run the campaign within its own divisions, attached offices and field formations. The Department of Personnel and Training is wrong; although it also deals with administration, the release does not connect it with this campaign. The Cabinet Secretariat is wrong as well, since monitoring inside the Ministry is described as happening at its own highest level rather than through that office. The Ministry of Panchayati Raj is wrong because the campaign described here runs across central government offices and their field units, not local bodies. Aspirants should hold the organiser, the participating ministry and the two phase dates together, since questions about this campaign usually test one of those three.

Q7.EnvironmentMedium

What is the full form of the REWARD programme under which the NRAA held its technical committee meeting?

  1. A.Rejuvenating Watersheds for Agricultural Resilience through Innovative Development
  2. B.Renewing Water Resources for Agriculture and Rural Development
  3. C.Restoring Ecology, Water and Rainfed Drylands
  4. D.Rural Employment through Watershed and Rainfed Development
Show answer

Correct answer: A. Rejuvenating Watersheds for Agricultural Resilience through Innovative Development

Explanation

The correct answer is Rejuvenating Watersheds for Agricultural Resilience through Innovative Development, the expansion given in the release for the programme under which the technical committee met at the NASC Complex in New Delhi. The second option is wrong; it is built from plausible words but does not match the expansion, and in particular it drops the idea of resilience, which is central to the programme's purpose. The third option is wrong for the same reason and adds terms about ecology and drylands that do not appear in the name. The fourth option is wrong because the programme is not an employment scheme, and confusing it with rural employment programmes is a common error. Candidates should also link the programme with the body running it, the National Rainfed Area Authority, which functions under the Ministry of Agriculture and Farmers Welfare, since acronym questions are often paired with the parent ministry.

Q8.DefenceEasy

SLINEX-26, which concluded at Visakhapatnam, is a bilateral maritime exercise between India and which country?

  1. A.Bangladesh
  2. B.Sri Lanka
  3. C.Maldives
  4. D.Indonesia
Show answer

Correct answer: B. Sri Lanka

Explanation

The correct answer is Sri Lanka. SLINEX is the bilateral maritime exercise held between the Indian Navy and the Sri Lanka Navy, and its name itself is formed from the two countries. The 13th edition, SLINEX-26, was conducted from 17 to 21 September 2026 and concluded at Visakhapatnam, with a harbour phase of professional exchanges and cross-deck visits followed by a sea phase of coordinated manoeuvres, air operations, night replenishment at sea and Special Forces drills. Option A, Bangladesh, is wrong because the exercise India conducts with the Bangladesh Navy carries a different name and did not feature in this release. Option C, Maldives, is wrong for the same reason; no Maldivian participation was reported in this exercise. Option D, Indonesia, is wrong because the release describes SLINEX strictly as an India-Sri Lanka bilateral activity, with no third navy taking part. The Ministry of Defence connected the drill to the MAHASAGAR vision and the Neighbourhood First policy.

Q9.SportsEasy

Who became India's first-ever Asian Games medallist in soft tennis?

  1. A.Jay Meena
  2. B.Mirabai Chanu
  3. C.Raiza Dhillon
  4. D.Maheshwari Chauhan
Show answer

Correct answer: A. Jay Meena

Explanation

The correct answer is Jay Meena. He won the bronze medal in the men's individual event in soft tennis and thereby became the first Indian ever to win an Asian Games medal in that sport. The Prime Minister described the result as a historic achievement for Indian soft tennis, said it marks a memorable new chapter for the game in India, and expressed the hope that it would inspire more youngsters to take up the sport. Option B, Mirabai Chanu, is wrong because she is a weightlifter and was congratulated the same day for a silver medal in the women's 49 kg event, not for anything in soft tennis. Option C, Raiza Dhillon, and option D, Maheshwari Chauhan, are wrong because both are shooters who were part of the women's skeet team that won a bronze medal, along with Parinaaz Dhaliwal.

Q10.Science & TechnologyEasy

How much support has the Technology Development Board approved for Ubifly Technologies under the RDI Fund?

  1. A.Rs 150 crore
  2. B.Rs 285 crore
  3. C.Rs 570 crore
  4. D.Rs 1,000 crore
Show answer

Correct answer: B. Rs 285 crore

Explanation

The correct answer is Rs 285 crore. The Technology Development Board, which functions under the Department of Science and Technology, approved that amount for Ubifly Technologies Private Limited of Chennai out of the Research Development and Innovation Fund, for its indigenous ePlane advanced air mobility solution. Option C is the figure most likely to mislead a candidate: it is the total approved cost of the project, not the Board's share, so the Board is meeting roughly half of the outlay while the rest comes from elsewhere. Option A and option D do not appear anywhere in the announcement and are simply plausible-looking amounts. The support is being extended through Optionally Convertible Debentures rather than as an outright grant, and its stated purpose is to carry the technology from Technology Readiness Level 6 to Level 9, which is the stage of an operationally demonstrated system.

Q11.Government SchemesEasy

MY Bharat, which has crossed 3 crore registered youth, is a platform of which ministry?

  1. A.Ministry of Education
  2. B.Ministry of Youth Affairs and Sports
  3. C.Ministry of Skill Development and Entrepreneurship
  4. D.Ministry of Women and Child Development
Show answer

Correct answer: B. Ministry of Youth Affairs and Sports

Explanation

The correct answer is the Ministry of Youth Affairs and Sports. Mera Yuva Bharat, or MY Bharat, is the national youth engagement platform of the Department of Youth Affairs within that ministry, and it has now gone past 3 crore registered youth in under three years. Option A, the Ministry of Education, runs school and higher education programmes and is not the owner of this platform, though students are among its users. Option C, the Ministry of Skill Development and Entrepreneurship, handles skilling missions and is a natural-looking but wrong choice here. Option D, the Ministry of Women and Child Development, deals with a different set of schemes altogether. The platform offers Experiential Learning Programmes, volunteering, quizzes, youth dialogues and community engagement, and an AI-enabled CV Builder has been added to help young users prepare professional profiles.

Q12.NationalEasy

Who graced the 75th annual convocation ceremony of the Maharaja Sayajirao University of Baroda?

  1. A.The Prime Minister
  2. B.The President of India
  3. C.The Vice-President
  4. D.The Union Education Minister
Show answer

Correct answer: B. The President of India

Explanation

The correct answer is the President of India, Droupadi Murmu. She attended the 75th annual convocation ceremony of the Maharaja Sayajirao University of Baroda at Vadodara in Gujarat and addressed the graduating students, telling them that education will be meaningful only if the country and society benefit from it. Option A, the Prime Minister, is wrong because the release comes from the President's Secretariat and names the President alone as the dignitary at the ceremony. Option C, the Vice-President, is a common distractor in convocation questions because Vice-Presidents also attend such events, but that is not the case here. Option D, the Union Education Minister, is likewise not named in this release. In her address the President pressed the case for a multidisciplinary approach, saying no important problem today can be solved within a single stream of study.

Q13.Science & TechnologyMedium

How many route kilometres of the Malkajgiri-Kamareddi section were upgraded from KAVACH Version 3.2 to Version 4.0?

  1. A.108 route kilometres
  2. B.208 route kilometres
  3. C.1,465 route kilometres
  4. D.512 route kilometres
Show answer

Correct answer: A. 108 route kilometres

Explanation

The correct answer is 108 route kilometres. That is the length of the Malkajgiri-Kamareddi section in the Hyderabad Division on which the system was carried up from the older edition to the newer one. The figure of 208 is wrong; no such length is mentioned anywhere in the announcement and it is offered only as a near-miss distractor. The figure of 1,465 is the trap in this question: that is the spread of the earlier Version 3.2 across South Central Railway as a whole, not the stretch newly upgraded, and aspirants who read hurriedly often swap the two. The figure of 512 is wrong as well, since it appears nowhere in the release. The safest way to hold this pair in memory is to remember that the newly upgraded piece is small and the older version's footprint on the zone is more than ten times larger.

Q14.Government SchemesMedium

How many visits have Ayushman Arogya Mandirs recorded, according to the Prime Minister's message?

  1. A.Over 100 crore
  2. B.Over 300 crore
  3. C.Over 500 crore
  4. D.Over 700 crore
Show answer

Correct answer: C. Over 500 crore

Explanation

The correct answer is over 500 crore. The Prime Minister used this figure to argue that healthcare is moving closer to every doorstep, since the centres named Ayushman Arogya Mandirs deliver primary care in neighbourhoods and villages rather than in distant hospitals. The option of over 100 crore is wrong, as the message names a far larger count and this figure only looks plausible to someone recalling the number of beneficiaries instead. Over 300 crore is wrong as well; it appears nowhere in the release and is included to catch a half-remembered answer. Over 700 crore is wrong because it overshoots the stated figure, and no higher count is claimed anywhere in the anniversary message. Candidates should note that this figure counts visits, not people, so it is much larger than the beneficiary count and the two must never be interchanged in an answer.

Q15.EconomyEasy

How many exhibitors took part in SEMICON India 2026?

  1. A.More than 400
  2. B.More than 600
  3. C.More than 800
  4. D.More than 1,000
Show answer

Correct answer: B. More than 600

Explanation

The correct answer is more than 600. The backgrounder records that the event brought together this many exhibitors, of whom close to three hundred were international companies, and treats that mix as a sign of the global interest now being shown in the country's semiconductor and electronics ecosystem. The first option is wrong because it falls short of the stated count and appears nowhere in the release. The third option is wrong for the opposite reason; it overstates the number, and no such figure is given. The fourth option is wrong as well, since a four-figure count is not claimed anywhere in the document. The useful pairing for an examination is the total against the international share, because a question may supply one and ask for the other, and the second figure is also the one that shows how much of the participation came from outside India.

Q16.NationalMedium

Which body oversees the global allocation of the Type Allocation Code used in IMEI numbers?

  1. A.GSMA
  2. B.TRAI
  3. C.Department of Telecommunications
  4. D.International Telecommunication Union
Show answer

Correct answer: A. GSMA

Explanation

The correct answer is the GSMA, the Global System for Mobile Communications Association. The backgrounder says it oversees the worldwide allocation of the Type Allocation Code, handing codes to manufacturers and brand owners, who then assign unique device identities to individual handsets. TRAI is wrong, because the regulator appears in the release only in connection with the rule restricting messaging for a day after a re-issued SIM is activated, not with code allocation. The Department of Telecommunications is wrong as well; it advises citizens on what to avoid and runs the registration and verification machinery in India, but the global code pool is not its to allocate. The International Telecommunication Union is wrong because the release does not assign it this role. A useful chain to memorise is that the association allocates the code, the manufacturer assigns the full identity, and the Indian portals then register it.

Q17.Science & TechnologyHard

When was MyWAVES launched within the WAVES OTT platform?

  1. A.20 November 2024
  2. B.1 May 2025
  3. C.23 March 2026
  4. D.21 July 2026
Show answer

Correct answer: C. 23 March 2026

Explanation

The correct answer is 23 March 2026. MyWAVES was opened inside the existing streaming platform on that date, and it changed the service from something people only watched into something they could contribute to, by letting citizens make, upload and share original short, vertical and episodic content. The first option is wrong because that is the date the streaming platform itself was launched at the film festival in Goa, not the date the creator section appeared. The second option is wrong because that is when the first edition of the summit opened in Mumbai. The fourth option is wrong because that is the day the Gems of India Challenge pilot began, which runs through the creator section but is a later and separate step. This question rewards candidates who keep a small timeline of the four dates rather than remembering them one at a time.

Q18.NationalMedium

When does the implementation phase of Special Campaign 6 run?

  1. A.15 September to 30 September 2026
  2. B.1 October to 15 October 2026
  3. C.2 October to 31 October 2026
  4. D.1 November to 30 November 2026
Show answer

Correct answer: C. 2 October to 31 October 2026

Explanation

The correct answer is 2 October to 31 October 2026. The campaign is split in two, and this is the second and longer part, in which the work actually happens across offices. The first option is wrong, and is the commonest error, because those are the dates of the preparation phase that comes before it; candidates who remember only one pair of dates usually give this answer. The second option is wrong because the implementation phase does not begin on the first of the month and does not end in the middle of it. The fourth option is wrong because the drive is completed within October and does not extend into the following month. A useful memory hook is that the implementation phase opens on the second day of October and runs to the last day of that month, so the whole of the month except its first day is covered.

Q19.EnvironmentHard

Who presided over the National Level Technical Committee meeting held under the REWARD programme?

  1. A.The Deputy Director General (NRM) of ICAR
  2. B.Dr Chandra Shekhar Kumar, CEO of the NRAA
  3. C.The Joint Secretary (Watershed Management), Department of Land Resources
  4. D.The Commissioner of the Watershed Development Department, Karnataka
Show answer

Correct answer: B. Dr Chandra Shekhar Kumar, CEO of the NRAA

Explanation

The correct answer is Dr Chandra Shekhar Kumar, Chief Executive Officer of the National Rainfed Area Authority. The release names him as presiding over the meeting and records his instruction that claims in the draft guidelines be validated against data actually collected under the programme. The Deputy Director General for natural resource management at ICAR is wrong; he attended and spoke on integrating the land resource inventory with hydrology, but did not preside. The Joint Secretary for watershed management in the Department of Land Resources is wrong as well; his contribution was the suggestion to shorten the time taken to prepare detailed project reports. The Commissioner of the watershed department in Karnataka is wrong because he joined the meeting online as a state participant. Aspirants should remember who said what, since questions on such meetings often attach a specific proposal to the wrong officer.

Q20.DefenceMedium

Which edition of SLINEX was held in September 2026?

  1. A.11th
  2. B.12th
  3. C.13th
  4. D.14th
Show answer

Correct answer: C. 13th

Explanation

The correct answer is 13th. The Ministry of Defence described the exercise held from 17 to 21 September 2026 as the 13th edition of the India-Sri Lanka bilateral maritime exercise, and it concluded at Visakhapatnam. Editions are the detail most often asked about recurring exercises, so the number should be memorised along with the venue and the year. Option A, the 11th, and option B, the 12th, refer to earlier editions of the series and not to the one that ended in September 2026. Option D, the 14th, would be a future edition and has not yet been held. The exercise ran in two phases: a harbour phase with cross-deck visits and sporting interaction, and a sea phase with coordinated manoeuvres, air operations, night replenishment at sea, slithering operations and Visit, Board, Search and Seizure drills that build interoperability between the two navies.

Q21.SportsMedium

Mirabai Chanu won a silver medal in which event?

  1. A.Women's 45 kg weightlifting
  2. B.Women's 49 kg weightlifting
  3. C.Women's 55 kg weightlifting
  4. D.Women's skeet individual
Show answer

Correct answer: B. Women's 49 kg weightlifting

Explanation

The correct answer is the women's 49 kg weightlifting event. The Prime Minister congratulated Mirabai Chanu on winning the silver medal in that category, saying her determination and consistency continue to inspire the nation and that India is proud of her. The weight class is the detail an examiner will test, so it should be memorised along with the colour of the medal. Option A, 45 kg, and option C, 55 kg, are other weight categories in the sport but are not the one in which she competed here. Option D, women's skeet individual, belongs to shooting and not to weightlifting; on the same day a women's skeet team bronze went to Parinaaz Dhaliwal, Maheshwari Chauhan and Raiza Dhillon, which is a separate result and a team event rather than an individual one.

Q22.Science & TechnologyMedium

The e200X being developed by Ubifly Technologies is which kind of aircraft?

  1. A.A two-seater trainer aircraft powered by a piston engine
  2. B.A three-seater zero-emission advanced air mobility aircraft
  3. C.An unmanned cargo drone with no pilot on board
  4. D.A regional turboprop airliner for sixty passengers
Show answer

Correct answer: B. A three-seater zero-emission advanced air mobility aircraft

Explanation

The correct answer is a three-seater zero-emission advanced air mobility aircraft. The release describes the e200X as configured for one pilot and two passengers, with a targeted range of 110 km and an ideal speed of 160 kmph, and with a landing gear built for both conventional and vertical landing so that it can operate out of relatively small spaces. Option A is wrong because the aircraft is electrically powered and seats three, not two, and it is not described as a trainer. Option C is wrong because the configuration explicitly includes a pilot on board along with two passengers, so it is not an unmanned platform. Option D is wrong on every count, as the e200X is a small electric machine and not a turboprop airliner. Its indigenous elements include vertical rotors, forward propellers, proprietary flight-control algorithms, power-distribution controllers and battery packs with integrated cooling.

Q23.Government SchemesMedium

On which date was the MY Bharat platform launched by the Prime Minister?

  1. A.12 January 2023
  2. B.15 August 2023
  3. C.31 October 2023
  4. D.26 January 2024
Show answer

Correct answer: C. 31 October 2023

Explanation

The correct answer is 31 October 2023. Prime Minister Narendra Modi launched Mera Yuva Bharat on that date, setting it up as a technology-enabled platform through which young Indians could join the country's development journey. At the launch he stressed the value of bringing the nation's youth on to a common platform. The growth since then is worth memorising along with the date: registrations crossed 2 crore in October 2025, went past 2.46 crore by August 2026, and have now crossed 3 crore. Option A is a date associated with National Youth Day observances rather than this launch. Option B and option D are national days that often appear as distractors in such questions but have no link to the platform's launch. The milestone was announced by the ministry on 23 September 2026.

Q24.NationalMedium

The Maharaja Sayajirao University, whose 75th convocation was held in September 2026, is located in which city?

  1. A.Ahmedabad
  2. B.Surat
  3. C.Vadodara
  4. D.Rajkot
Show answer

Correct answer: C. Vadodara

Explanation

The correct answer is Vadodara, in Gujarat. The President attended the 75th annual convocation of the Maharaja Sayajirao University of Baroda in that city, and the university takes its name from the ruler of the former princely state of Baroda, which is the older name of Vadodara itself. That link between the two names is what the question is really testing. Option A, Ahmedabad, option B, Surat, and option D, Rajkot, are other major cities of Gujarat, and each is home to universities of its own, but none of them hosts this institution. The President noted that the university has spent 75 years bringing several streams of knowledge together and said higher education institutions must remain alert and dynamic in that direction as the country works towards the goal of a developed India.

Q25.Science & TechnologyMedium

Which safety certification level is required for the KAVACH system?

  1. A.Safety Integrity Level-2
  2. B.Safety Integrity Level-3
  3. C.Safety Integrity Level-4
  4. D.Safety Integrity Level-5
Show answer

Correct answer: C. Safety Integrity Level-4

Explanation

The correct answer is Safety Integrity Level-4, usually written SIL-4. The release describes the train protection system as heavily dependent on technology and therefore obliged to carry safety certification of the highest order, which it identifies as SIL-4. Level-2 is wrong because it is a lower grade and would not satisfy a system that can apply brakes on a running train without human action. Level-3 is wrong for the same reason; it is one step below the grade actually named. Level-5 is wrong because the release names Level-4 as the highest order of certification here, so a fifth level is not what the system is held to. In examinations this fact is often paired with the system's purpose, so remember together that KAVACH is an indigenous Automatic Train Protection system, that it guards against Signal Passing at Danger, and that it is certified at SIL-4.
