Daily Current Affairs Quiz: November 03, 2025

Answer: B [Only two]
Explanation:

Statement 1 is incorrect: Molniya orbit is not a geostationary orbit. Geostationary orbits are circular and positioned over the equator, while Molniya orbits are highly elliptical and inclined to cover high latitudes.

Statement 2 is correct: It is a highly elliptical orbit designed so that satellites spend most of their time over high-latitude regions, providing prolonged coverage to areas like Russia and northern Europe.

Statement 3 is correct: The Soviet Union first developed and used Molniya orbits for communication and early warning satellites to ensure better coverage over its high-latitude territory.

Answer: D [To directly measure the Sun's neutrino flux and understand its core processes]
Explanation:

Option A is incorrect: Aditya-L1 is designed to study the solar corona and coronal mass ejections (CMEs), which are key to understanding solar activity and its impact on space weather.

Option B is incorrect: One major goal is to investigate how the chromosphere and corona are heated to very high temperatures, an important question in solar physics.

Option C is incorrect: The mission includes instruments to analyze in-situ particles and plasma at the Lagrange Point (L1) to enhance understanding of space weather conditions.

Option D is correct: Aditya-L1 does not study solar neutrinos or the Sun’s core processes; such objectives require underground or specialized neutrino observatories, not space-based solar missions.

Answer: C [Both 1 and 2]
Explanation:

Statement 1 is correct: The National Supercomputing Mission (NSM) is jointly implemented and steered by the Department of Science and Technology (DST) and the Ministry of Electronics and Information Technology (MeitY) to enhance India’s supercomputing capacity.

Statement 2 is correct: PARAM Shivay, installed at IIT (BHU) Varanasi in 2019, was the first supercomputer assembled indigenously in India under the NSM, marking a major step in self-reliant high-performance computing.

Answer: C [All four]
Explanation:

Statement 1 is correct: Nanotechnology is used in solar cells to improve light absorption and electron transport, thereby increasing the efficiency of solar energy conversion.

Statement 2 is correct: Nanomaterials such as carbon nanotubes and graphene are employed to create stronger, lighter materials used in the aerospace industry for enhanced performance and fuel efficiency.

Statement 3 is correct: Nanotechnology enables advanced water desalination methods using nanomembranes and nanofilters that remove salts and contaminants more efficiently than conventional techniques.

Statement 4 is correct: In the food industry, nanoparticles are used to enhance flavor, texture, and nutrient delivery, representing a growing field known as nanofood technology.

Answer: A [Quantum computing]
Explanation:

Option A is correct: Quantum computing represents the future trend in supercomputing, as it leverages quantum bits (qubits) to perform complex computations exponentially faster than classical systems.

Other options are incorrect: Punch cards, vacuum tubes, and magnetic tape storage are outdated technologies from earlier computing generations, no longer relevant to modern or future supercomputing advancements.
