In the NRIDA study design, how long will the baseline survey conducted before road construction last?

The correct answer is IIM Kolkata. The National Rural Infrastructure Development Agency, which works under the Ministry of Rural Development, signed the Memorandum of Understanding with the Indian Institute of Management Kolkata for a four-year longitudinal study of roads built under PMGSY-IV and PM-JANMAN. The signatories were NRIDA Director General Aditi Singh and IIM Kolkata Director Alok Kumar Rai, with Rural Development Secretary Rohit Kansal present. Option A, IIM Ahmedabad, is a different management institute and was not party to this agreement, so it is wrong. Option C, IIT Roorkee, is an engineering institute and was not involved here either. Option D, the National Institute of Rural Development and Panchayati Raj, works in the same sector and therefore looks plausible, but it is not the partner named in this MoU, so it is also incorrect.

The correct answer is 250. The study will examine that many rural roads, spread across ten States and Union Territories, fifty districts and one hundred and fifty blocks, with a household survey of roughly five thousand families to capture changes in mobility, accessibility and socio-economic conditions. Option A is the number of blocks covered rather than the number of roads, which makes it a tempting but incorrect choice. Option B and option D are round figures that do not match the coverage announced, so both are wrong. Aspirants should keep the four coverage numbers in order, from States and Union Territories to districts, then blocks and finally roads, because questions often swap one of them for another. The States and Union Territory in the study are Andhra Pradesh, Assam, Chhattisgarh, Jammu and Kashmir, Jharkhand, Madhya Pradesh, Odisha, Rajasthan, Sikkim and Uttarakhand.

The correct answer is in a Union Ministry office. As part of Swachhata Hi Seva 2026 the Union Minister inaugurated a Reduce, Reuse and Recycle Centre at Sankalp Bhawan in New Delhi, and it has been described as the first such centre in a Union Ministry office. The purpose is to promote sustainable consumption, reuse, resource recovery and circularity within government workplaces, so that the offices framing the policy also practise it. Option A, a railway station, and options C and D, a municipal corporation building and a central university campus, are all places where such collection points are plausible, and RRR centres have been popularised widely, but the distinction claimed here relates specifically to a Union Ministry office. Hence option B is correct.

The correct answer is IIT Kanpur. The Ministry launched the third cohort of startups working on sanitation and waste management in collaboration with the Startup Incubation and Innovation Centre at IIT Kanpur. With 13 startups joining this cohort, the Mission completed its national target of onboarding and incubating 75 startups across the waste value chain. The Minister of State also used the occasion to note that India has emerged as the world's third-largest startup ecosystem. Options A, C and D name other leading technical institutions of the country, each of which runs its own incubation facilities, which makes them plausible; however, none of them was named as the partner for this cohort. The cohort is focused on pioneering solutions in sanitation and waste management. So option B is the answer.

The correct answer is Durgapur. The Ministry set up the Swachh Bharat Test Bed and Innovation Centre at Durgapur in collaboration with CSIR-CMERI, and it is meant to serve as a national facility for research, product development, testing, validation, certification and capacity building in sanitation technologies. Option B, Kanpur, is a plausible distractor because the third cohort of Swachhata startups was launched with the Startup Incubation and Innovation Centre at IIT Kanpur, but that is a separate activity from the Test Bed. Option C, Indore, is widely associated with urban cleanliness rankings but was not named as the Test Bed site. Option D, Pune, was not mentioned at all. The centre was created because the Mission has consistently placed research and innovation at the heart of its Swachhata work. Hence option A is correct.
