Which two institutions jointly pursued the record road and signed a Technology Transfer Agreement at the event?

The correct answer is Raigarh, Chhattisgarh. The record road runs 1.85 km and was pursued jointly by the CSIR-Central Road Research Institute of New Delhi and Jindal Steel Limited, with the record conferred at an event addressed by Dr Jitendra Singh. Option A, Angul in Odisha, is a genuine part of the story but belongs to the next stage: CSIR-CRRI has received a work order for a 40-km road in Odisha from the Jindal Steel plant there, which is meant to take the technology well beyond the present record. Option C, Hazira in Gujarat, is where the technology was first demonstrated on a six-lane road to the port, and a 1.1-km slag road was later laid inside Hazira Port itself, but neither is the record stretch. Option D, Bhilai, is a well-known steel town used here only as a distractor. Keep the record with Raigarh and the future project with Angul.

The correct answer is 40 per cent. The Minister said the technology can cut construction cost by around this share while delivering four times the strength of a conventional road, and can stretch the maintenance cycle so that major maintenance is needed only after about fifteen years in suitable applications. He described the result as a breakthrough not only for road engineering but for the wider infrastructure economy, since it saves money and conserves natural aggregates obtained through mining and quarrying at the same time. The other options are simply higher or lower shares offered to test whether the candidate has the exact figure. The three claims travel together in question papers, so it is worth memorising them as a set: about forty per cent cheaper, four times stronger, and maintenance pushed to about fifteen years.

The correct answer is the Prime Minister of India. The release was issued by the Prime Minister's Office and records that Prime Minister Narendra Modi hailed the launch as yet another outstanding achievement by ISRO and a proud moment for the nation. He shared his remarks in a post on X. He said the successful launch reflects the excellence, innovation and growing capabilities that define India's space sector, and he added that the deepening partnership between ISRO and Indian industry is adding new strength and scale to the space programme while expanding the country's capabilities across the entire space ecosystem. Option A, the President, and option B, the Vice-President, are the holders of the two offices students most often substitute for the Prime Minister in such questions, but neither is the source of these remarks. Option D, the Minister of Education, has no connection with a space launch and is easy to eliminate. Note also who the remarks were addressed to: ISRO, the Indian Space Research Organisation.

The correct answer is Geosynchronous orbit. The distinction claimed for EOS-05 in this release is precisely this: it is India's first-ever imaging satellite from Geosynchronous orbit. That is the single fact that turns an otherwise routine launch into an examinable milestone, and it is the phrase the Prime Minister himself used. A spacecraft in this orbit keeps pace with the rotation of the Earth, so it remains over broadly the same region rather than passing over it and moving on. Option A, low Earth orbit, is where a great many satellites operate, but the release does not place EOS-05 there and a low orbit would not support the claim of a first. Option B, Sun-synchronous orbit, and option D, polar orbit, are the orbits associated with earlier remote sensing spacecraft, which is exactly why they make tempting distractors. Neither is named in this release. Remember the wording of the first: imaging satellite, Geosynchronous orbit.

The correct answer is GSLV-F17. The release records that ISRO carried out the successful launch of GSLV-F17 carrying EOS-05, and that the Prime Minister praised the space agency for the achievement. GSLV is short for the Geosynchronous Satellite Launch Vehicle, and the suffix F17 identifies this particular flight of that rocket family. Option A names the PSLV, the Polar Satellite Launch Vehicle, which is a different rocket family and is not the vehicle mentioned in this release. Option C names LVM3, the heavy-lift vehicle, which also does not appear here. Option D names the SSLV, the Small Satellite Launch Vehicle, again a different family with no role in this launch. Students often confuse the rocket with the satellite, so the safest way to remember this item is as a pair: the rocket was GSLV-F17 and the satellite it carried was EOS-05. The Prime Minister called the flight a proud moment for the nation and said it reflects the excellence, innovation and growing capabilities of India's space sector.
