SAT Reading: Science questions

In Passage 1, the analogy to "revelers on a ship" (line 32 ("revelers on a ship,"), ) serves mainly to

stress the dynamic relationship of members within a galaxy group.

Based on Passage 1, which of the following choices suggests that the expansion of the universe is accelerating?

Galaxy clusters are moving further apart

Which type of evidence is used extensively in passage 2 but not in passage 1?

Results from a study.

In Passage 2, the situation described in paragraph 3 is most similar to

a natural phenomenon that is difficult to document because it is rarely seen.

The authors of both passages would agree that intergalactic collisions

are inevitable within confined groups.

It can reasonably be inferred from Passage 2 that collisions throughout the universe

are largely undocumented.

Which choice best supports the answer to the previous question?

lines 11-13 ("But . . . dominate.")

Which choice provides the best evidence for the answer to the previous question?

lines 45-48 ("Of . . . progress.")

Compared with the tone of passage 2, passage 1 is more

lyrical.

As used in line 6 ("attractive") , "attractive" most nearly means

pulling.

The author of Passage 1 claims that our galaxy and the Andromeda Galaxy will collide mainly because

they are bound together by gravity.
