Correct

Solution: b)

 

Statement 3 is incorrect.

 

The solar weather and environment affect the weather of the entire system. Variations in this weather can change the orbits of satellites or shorten their lives, interfere with or damage onboard electronics, and cause power blackouts and other disturbances on Earth. Knowledge of solar events is key to understanding space weather.

 

Every storm that emerges from the Sun and heads towards Earth passes through L1, and a satellite placed in the halo orbit around L1 of the Sun-Earth system has the major advantage of continuously viewing the Sun without any occultation/eclipses.

 

L1 refers to Lagrangian/Lagrange Point 1, one of five points in the orbital plane of the Earth-Sun system. Lagrange Points, named after Italian-French mathematician Josephy-Louis Lagrange, are positions in space where the gravitational forces of a two-body system (like the Sun and the Earth) produce enhanced regions of attraction and repulsion. These can be used by spacecraft to reduce fuel consumption needed to remain in position. The L1 point is home to the Solar and Heliospheric Observatory Satellite (SOHO), an international collaboration project of NASA and the European Space Agency (ESA).

Only Statement 1 is correct.

 

The Centre enhanced the buffer stock of onion from three lakh tonnes to five lakh tonnes.

 

The Union Consumer Affairs Department has directed the National Cooperative Consumers’ Federation of India (NCCF) and the National Agricultural Cooperative Marketing Federation of India (NAFED) to procure one lakh tonne each to achieve the additional procurement target alongside calibrated sale of the procured stocks in major consumption centres.

 

NCCF, as an organization to promote consumer cooperative movement in the country, aspires to facilitate the voluntary formation and democratic functioning of cooperatives, based on self-reliance and mutual aid for overall economic betterment and financial autonomy. It functions under Ministry of Consumer Affairs, Food & Public Distribution.

Circuit breakers are triggered to prevent markets from crashing due to a panic induced sale of stocks. This can happen due to many reasons which lead to stockholders in the market feeling that their stocks are overvalued. Thus, they enter into a sell-off.

 

Circuit breakers temporarily halt trading and thus stop the sell-off. Effectively, circuit-breakers cap how much the value of a stock can fall in a single day/trading session and in doing so, create a more stable market overall.
