Question

Paraphrase the given lines from the passage:
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 now attracts more matter to it and its gravity increases further, causing it to begin to contract. As it contracts its density increases which increases its gravity even more so that it picks up even more matter and contracts even further.

• A. If the gas moves, a tiny region may become denser than the surrounding gas. Its gravity strengthens and it pulls more matter as it contracts.
• B. When the gas is disturbed, a spherical region becomes denser so that its gravity becomes stronger. This causes it to attract more matter towards itself and become denser.
• C. A small region of gas becomes dense and starts attracting matter, increasing its density and gravity. This continues as it contracts further.
• D. Gravity keeps increasing, as does the size of the gas.

Answer 1

Answer: (A), (B)

If the gas moves, a tiny region may become denser than the surrounding gas. Its gravity strengthens and it pulls more matter as it contracts.
When the gas is disturbed, a spherical region becomes denser so that its gravity becomes stronger. This causes it to attract more matter towards itself and become denser.

Summary is an overview of content that provides the reader with the overarching theme of a text, but does not expand on specific details.

The correct answer is Option A and Option B. Both the options have adequate and appropriate information to be called the summary of the given paragraph. The language is different in the two given summaries but the content is same.

Option C is incorrect as it misses some important facts from the paragraph that should be written in its summary.

Option D is incorrect as it is too precise and has no important details to discuss the theme of the given paragraph.
