Read the passage and answer the questions below
There are several scientific theories as to why dinosaurs
became extinct. One theory has to do with asteroids.
Asteroids are rocky objects that orbit the sun. According
to this theory, an asteroid collided with the earth millions
of years ago, causing disastrous changes in the earth's
climate, such as tsunamis, high winds, and dust in the
atmosphere that blocked the sun. As a result, dinosaurs
could no longer survive. Some scientists believe that if
this asteroid had not collided with the earth, dinosaurs
would not have become extinct.
