Question
1. Matter that falls into a black hole can form an
external accretion disk heated by friction, forming some of the brightest objects in the universe. 2. If there are other stars orbiting a black hole, their orbits can be use to determine the black hole's mass and location. 3. Such observations can be used to exclude possible alternatives such as neutron stars. In the following question, three sentences are given, revolving around the same theme or idea. Decide which of the sentences are grammatically and meaningfully correct and mark the question accordingly.Solution
(c) is the right answer as only 1 and 3 are grammatically and meaningfully correct. In 2, replace CAN BE USE with CAN BE USED as the passive voice construction requires the verb in its third form to follow. Hence, the verb "use" should be in its third form to appear after "be", making option 2 grammatically incorrect.
