The Current Affairs questions are based on sources like ‘The Hindu’, ‘Indian Express’ and ‘PIB’, which are very important sources for UPSC Prelims Exam. The questions are focused on both the concepts and facts. The topics covered here are generally different from what is being covered under ‘Daily Current Affairs/Daily News Analysis (DNA) and Daily Static Quiz’ to avoid duplication. The questions would be published from Monday to Saturday before 2 PM. One should not spend more than 10 minutes on this initiative.

Consider the following statements about Einstein Ring
Choose the correct statements:
Solution (a)
Statement Analysis
| Statement 1 | Statement 2 | Statement 3 |
| Correct | Correct | Incorrect |
| · In Einstein’s theory of Gravity, mass can bend the path of light.
· It is created when the light from distant objects, like galaxies, pass by an extremely large mass. · A ring-shaped image produced in this way is known as an Einstein Ring. |
· A gravitational lens happens when astronomers on Earth look toward a huge galaxy or galaxy cluster, so massive that its gravity distorts any light passing near.
· The massive object acts like a lens in space, spreading the light out, often to produce multiple images of a more distant object that happens to be shining behind it. · Or, if the distant background object and the intervening massive galaxy are perfectly aligned, the gravitational lens may spread the light to produce an image of a ring in space. |
· For the lensing by a black hole, infinite number of Einstein rings are formed by the light rays which wind around the black hole nearly on the photon sphere, which are called relativistic Einstein rings. |

Solution (b)
| Option b |
| Correct |
| · The Kushiyara River is a distributary river in Bangladesh and Assam, India.
