Science and Technology News Questions and Answers

Answer: D

A is false, but R is true.

BharatGen, launched in September 2024, is India's government-funded initiative to build generative AI models for Indian languages. It was launched by the Department of Science and Technology (Ministry of Science and Technology) under its National Mission on Interdisciplinary Cyber-Physical Systems, with IIT Bombay leading the consortium, not by the Ministry of Electronics and Information Technology. So the Assertion is wrong on the ministry.

The Reason correctly states BharatGen's aims: home-grown foundation models that reduce dependence on foreign technology and serve India's many languages.

Answer: B

PSLV-C37 carried 103 co-passenger satellites.

On 15 February 2017 ISRO's PSLV-C37 placed 104 satellites in orbit in one launch, a world record at the time. One was the main payload, the 714 kg Cartosat-2 series satellite, and the other 103 were co-passengers: two Indian nano-satellites and 101 from abroad, most of them from the USA.

\[ 104 - 1 = 103 \]

104 is the trap, the total including Cartosat-2. 102 and 112 match neither count.

Answer: A

The incorrectly explained term is Dragonfly.

NASA's Dragonfly is a rotorcraft lander being sent to Titan, Saturn's largest moon, to study its organic chemistry and possible habitability. It has nothing to do with solar flares or the Martian regolith.

The others are correctly described. 'Grey goo' is the hypothetical scenario of self-replicating nanomachines consuming the biosphere, the Hyperloop is a proposed high-speed transport in low-pressure tubes, and INS Tabar is a Talwar-class stealth frigate of the Indian Navy.
