Science & Technology MCQs

The breakthrough often involves innovative sorbents, membranes, or electrochemical processes that are more selective, require less energy for regeneration, and are thus more economically viable.

The breakthrough focuses on developing more efficient and cost-effective methods to capture carbon dioxide directly from sources like power plants or from the ambient air.

The AI tool aims to assist radiologists by providing a faster and potentially more accurate analysis of medical images, leading to earlier and more effective treatment.

The AI tool leverages advanced machine learning algorithms to analyze patterns in medical images, such as mammograms, to identify subtle indicators of malignancy.

The AI tool developed by IIT Madras focuses on analyzing mammograms to detect early signs of breast cancer, aiming to improve diagnostic accuracy and speed.

INSAT-4DS is a follow-on mission to INSAT-4A, designed to provide enhanced communication services and replace the aging transponders of its predecessor.

The GSLV Mk III (now LVM3) is ISRO's heavy-lift launch vehicle, capable of launching heavy communication satellites like INSAT-4DS into geostationary transfer orbit.

INSAT-4DS is designed to augment the existing communication satellite fleet of ISRO, primarily for telecommunications, broadcasting, and other communication services.

Scientific interest in lunar water ice, particularly in permanently shadowed regions near the poles, is high due to its implications for future human missions and resource utilization. Therefore, polar regions are prime targets for sample return missions.

A sample return mission, like Chandrayaan-4 is anticipated to be, necessitates the capability to lift off from the Moon and rendezvous with an orbiting spacecraft. Therefore, a lunar ascent module is a critical technological requirement.
