Question 1: (D)

Explanation : It is used to detect and study muon particles produced during interaction of atoms in atmosphere with cosmic rays. For the first time in the world, researchers at the GRAPES-3 muon telescope facility in Ooty have measured the electrical potential, size and height of a thundercloud that passed overhead on December 1, 2014. At 1. 3 gigavolts (GV), this cloud had 10 times higher potential than the previous record in a cloud.

Question 2: (A)

Explanation : BRI consists of maritime routes as well as communication networks. Italy is the first G7 country to join the initiative recently.

Question 3: (A)

Explanation : The RBI decided to inject rupee liquidity for three years through long-term foreign exchange Buy/Sell swap. Under this, the RBI will buy up to $5 billion from the market via auction on March 26, and simultaneously sell it back to the same counterparties effective March 2022.

Whatever amount of dollars get mopped up via these operations will reflect in the RBI’s foreign exchange reserves for the tenor of the swap while also reflecting in RBI’s forward liabilities. Meanwhile, the system gets rupee equivalent liquidity for the same amount and for the same duration.

Question 4: (C)

Explanation : A Japanese space probe named after a falcon, Hayabusa 2, has touched down on an asteroid more than 300 million km from Earth on a mission to seek clues about the origins of life, Japan's space agency said.

The spacecraftrecently landed on the asteroid Ryugu, just 900 metres in diameter. It was difficult to pick a landing spot on the asteroid's rocky surface.

Hayabusa 2 fired a small projectile into the surface of Ryugu to collect particles which scientists hope the spacecraft will bring back to Earth for analysis.

Question 5: (A)

Explanation: Statement 3 is correct while statements 1 and 2 are wrong.

In reality, all economies are mixed economies where some important decisions are taken by the government and the economic activities are conducted through the market. The only difference is in terms of the extent of the role of the government in deciding the course of economic activities. In the United States of America, the role of the government is minimal. The closest example of a centrally planned economy is the China for the major part of the twentieth century. In India, since Independence, the government has played a major role in planning economic activities. However, the role of the government in the Indian economy has been reduced considerably in the last couple of decades.

Question 6: (A)

Explanation: Definition 1 is correct while definition 2 is wrong.

  • Total Utility: Total utility of a fixed quantity of a commodity (TU) is the total satisfaction derived from consuming the given amount of some commodity.
  • Marginal Utility: Marginal utility (MU) is the change in total utility due to consumption of one additional unit of a commodity.

Question 7: (A)

Explanation: Option (a) is correct.

Ultrasound scanner is an instrument which uses ultrasonic waves for getting images of internal organs of the human body. A doctor may image the patient’s organs such as the liver, gall bladder, uterus, kidney, etc. It helps the doctor to detect abnormalities, such as stones in the gall bladder and kidney or tumours in different organs. In this technique the ultrasonic waves travel through the tissues of the body and get reflected from a region where there is a change of tissue density. These waves are then converted into electrical signals that are used to generate images of the organ. These images are then displayed on a monitor or printed on a film.

Question 8: (B)

Explanation: Option (b) is correct.

Antibiotics commonly block biochemical pathways important for bacteria. Many bacteria, for example, make a cell-wall to protect them. The antibiotic penicillin blocks the bacterial processes that build the cell wall. As a result, the growing bacteria become unable to make cell-walls, and die easily. Human cells don’t make a cell-wall anyway, so penicillin cannot have such an effect on us. Penicillin will have this effect on any bacteria that use such processes for making cell-walls. Similarly, many antibiotics work against many species of bacteria rather than simply working against one. But viruses do not use these pathways at all, and that is the reason why antibiotics do not work against viral infections. If we have a common cold, taking antibiotics does not reduce the severity or the duration of the disease.

Question 9: (D)

Explanation: All statements are correct.

Italian traveller Nicolo Konti came to Vijaynagara in the first half of the fifteenth century. Persian traveller Abdur-Razzak had visited Vijaynagar during the reign of Dev Raya II.

Question 10: (C)

Explanation: Both statements are correct.

Turkish used both the dome and arch method as well as the slab and beam. They used fine quality mortar in their buildings. Turks used Hindu motifs such as the bell motif, swastika lotas etc.
