# Short Passages Comprehension -XVI

## Please study carefully the comprehension given below. The passages is followed by a set of questions choose the best answer to each question.

One simple concept lies behind the formation of the stars : gravitational instability. The concept is not new. Newton first perceived it late in the 17th Century. Imagine a uniform, static cloud of gas in space. 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. The process continues until the small region of gas finally forms a gravitationally bound object.

(a) uniting
(b) varying
(c) gaseous
(d) unvarying

Ques 4. What does the underlined word ‘it’ stands for in the passage?
(a) gravitational instability
(b) cloud of gas
(c) small spherical denser region
(d) matter

Ques 5. The author provides information that answers which of following questions?
(1) What causes the disturbances that changes the cloud from its original static condition?
(2) How does this small region’s increasing density affect its gravitational field?
(3) hat is the end result of the gradually increasing concentration of the small region of gas?
