1. Question
With reference to Gamma-Ray Bursts (GRBs), consider the following statements:
GRBs typically occur following the explosion of massive stars or the fusion of compact stars.
These bursts release energy equivalent to that of over a billion billion suns.
Observing GRBs provides data on the history and evolution of the universe.
GRBs can be easily observed from Earth with the naked eye as they last for a few seconds.
Which of the statements given above is/are correct?CorrectAnswer and Explanation:
Answer: (b) 1, 2, and 3 onlyExplanation:
Statement 1 is correct. GRBs typically occur following the explosion of massive stars, at least 20 times larger than the sun, or from the fusion of compact stars.
Statement 2 is correct. These bursts emit extremely bright cosmic beams, releasing energy equivalent to that of over a billion billion suns.
Statement 3 is correct. Observing GRBs provides valuable data on the history and evolution of the universe, as the gamma-ray rays from GRBs carry information about the gas clouds and galaxies they pass through.
Statement 4 is incorrect. GRBs are challenging to observe because they can appear randomly in the sky and last only a few seconds, often getting absorbed by Earth’s atmosphere. Probes in space are essential for capturing these bursts, making them not easily observable from Earth with the naked eye.
Therefore, the correct answer is (b) 1, 2, and 3 only.IncorrectAnswer and Explanation:

The Caspian Sea is the world’s largest inland body of water, variously classed as the world’s largest lake or a full-fledged sea.
As an endorheic basin, it lies between Europe and Asia; east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau of Western Asia.
• An endorheic basin is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation.
• Russia, Iran, Azerbaijan, Kazakhstan and Turkmenistan all bordering the Caspian Sea ,have agreed in principle on how to divide it up.IncorrectAns;- a) Only 1 and 2
