Answer (c)

Explanation:

Scientists find an exotic black hole

• Astronomers have spotted in a galaxy adjacent to our Milky Way what they are calling a cosmic “needle in a haystack” - a black hole that not only is classified as dormant but appears to have been born without the explosion of a dying star.
• Researchers said this one differs from all other known black holes in that it is “X-ray quiet” - not emitting powerful X-ray radiation indicative of gobbling up nearby material with its strong gravitational pull - and that it was not born in a stellar blast called a supernova.
• Black holes are extraordinarily dense objects with gravity so intense not even light can escape. This one, with a mass at least nine times greater than our sun, was detected in the Tarantula Nebula region of the Large Magellanic Cloud galaxy and is located about 160,000 light years from Earth. A light year is the distance light travels in a year (9.5 trillion km).
• An extremely luminous and hot blue star with a mass about 25 times that of the sun orbits with this black hole in a stellar This so-called binary system is named VFTS 243. The researchers believe the companion star eventually also will become a black hole and could merge with the other one.
• Dormant black holes, thought to be relatively common, are hard to detect because they interact very little with their Numerous prior proposed candidates have been debunked with further study, including by members of the team that uncovered this one.

Q3. Consider the following statements

1. The Aravalli Range is rich in natural resources including minerals
2. It serves as a check to the growth of the western desert
3. It gives rise to several rivers, including the Banas, Luni, Sakhi, and Sabarmati

Which of the above statements is/are correct?

1. 1 and 2 only
2. 2 and 3 only
3. 1 and 3 only
4. 1, 2 and 3

Answer (d)

Explanation:

Aravalli Range, also spelled Aravali Range, hill system of northern India, running northeasterly for 350 miles (560 km) through Rajasthan state. Isolated rocky offshoots continue to just south of Delhi. The series of peaks and ridges, with breadths varying from 6 to 60 miles (10 to 100 km), are generally between 1,000 and 3,000 feet (300 and 900 metres) in elevation. The system is divided into two sections: the Sambhar-Sirohi ranges, taller and including Guru Peak on Mount Abu, the highest peak in the Aravalli Range (5,650 feet [1,722 metres]); and the Sambhar-Khetri ranges, consisting of three ridges that are discontinuous. The Aravalli Range is rich in natural resources (including minerals) and serves as a check to the growth of the western desert. It gives rise to several rivers, including the Banas, Luni, Sakhi, and Sabarmati. Though heavily forested in the south, it is generally bare and thinly populated, consisting of large areas of sand and stone and of masses of rose- coloured quartzite.

Q4. Which country is the largest supplier of Bulk Drugs?

1. India
2. USA
3. China
4. Germany

Answer (c)

Explanation:

The Covid-19 global pandemic has brought to the fore the intricate interdependencies that exist within the international pharmaceutical market. China, the epicentre of the global outbreak, is also the world’s largest supplier of active pharmaceutical ingredients (APIs) also known as bulk drugs. India, which is a leading exporter of generic drugs across the world depends on China for more than two-thirds of its bulk drug needs. Estimates indicate that India supplies upto 50% of the United States’ generic drug needs, and vulnerabilities caused by Covid-19 have caused disruptions across global pharmaceutical supply chains. Perhaps this is also a good opportunity for India to re-assess dependencies and plan for the future.
