Daily Current Affairs Quiz: March 12, 2026

Option [a] is incorrect: The Proba-3 mission is not related to Mars exploration. It focuses on studying the Sun’s outer atmosphere rather than the atmosphere of another planet.

Option [b] is correct: Proba-3 is a European Space Agency mission designed to demonstrate high-precision formation flying between two satellites. One spacecraft blocks the Sun’s bright disc while the other observes the solar corona, effectively creating an artificial solar eclipse in space.

Option [c] is incorrect: Asteroid-deflection technologies are tested in missions such as NASA’s DART, not in the Proba-3 mission.

Option [d] is incorrect: Although some satellites monitor Earth’s climate, Proba-3 is dedicated to solar research, particularly studying the Sun’s corona and solar activity.

Option [a] is incorrect: BharatNet is not designed specifically for satellite-based internet in cities. Its primary focus is expanding broadband connectivity in rural areas, especially at the Gram Panchayat level.

Option [b] is incorrect: Submarine cables connect countries and continents through international internet infrastructure, whereas BharatNet focuses on domestic rural broadband connectivity within India.

Option [c] is incorrect: Semiconductor manufacturing relates to electronics production and industrial policy, which is unrelated to the objective of the BharatNet Project.

Option [d] is correct: The BharatNet Project aims to provide high-speed broadband connectivity through optical fibre to all Gram Panchayats in India, enabling digital services such as e-governance, telemedicine, online education and digital banking in rural areas.

Option [a] is incorrect: Content indexed by search engines and easily accessible through browsers forms the Surface Web, which represents only a small portion of the total internet.

Option [b] is incorrect: Private databases, online banking portals and subscription-based services belong to the Deep Web, which is not indexed by search engines but is still accessible with proper authentication.

Option [c] is correct: The Dark Web (Darknet) is a hidden section of the internet accessible only through specialized tools such as Tor (The Onion Router) and operates on encrypted networks, offering high anonymity for users.

Option [d] is incorrect: Government cybersecurity networks are secure administrative systems, not the hidden encrypted networks that define the Dark Web.

Option [a] is incorrect: White phosphorus is not chemically stable in air. Instead, it is highly reactive and can ignite spontaneously when exposed to oxygen at relatively low temperatures.

Option [b] is correct: White phosphorus ignites on contact with air at temperatures above about 30°C and burns intensely, producing thick white smoke composed mainly of phosphorus oxides.

Option [c] is incorrect: The chemical does not require water to react. In fact, it reacts readily with oxygen in the air and burns vigorously when exposed.

Option [d] is incorrect: White phosphorus is not classified as a biological agent. It is a chemical substance used in military contexts mainly for smoke screens, illumination and incendiary purposes.

Option [a] is correct: A War of Attrition focuses on gradually weakening the opponent by depleting its resources, manpower, equipment and morale over time until it can no longer sustain the conflict.

Option [b] is incorrect: Rapid territorial conquest is associated with strategies such as blitzkrieg, which aim for quick decisive victories rather than prolonged conflict.

Option [c] is incorrect: Cyber warfare may be part of modern conflicts, but it does not define the concept of a war of attrition, which mainly emphasizes sustained physical and economic pressure.

Option [d] is incorrect: A war of attrition involves continuous military engagement, not avoidance of confrontation through diplomacy alone.
