Question

What does the word 'it' in the sentence "gas around it.....stronger" stand for in the passage?

• A. Gravitational instability
• B. Cloud of gas
• C. Small, spherical, denser region
• D. Matter

Answer 1

Answer: (C)

Small, spherical, denser region

In the sentence "Imagine then that the gas is somehow disturbed so that one, small, spherical region becomes a little denser than the gas around it so that the small region's gravitational field becomes slightly stronger. "

'It' refers to the 'small, spherical, denser region'. The pronoun 'it' is used instead of the noun 'region' in the given sentence. Hence option C is the correct answer.

The cloud of gas, gravitational instability or matter is not the subject of the given sentence. Hence, options A,B,D are incorrect.
