rather than on land. Because of the fact that they are mammals, scientists have
believed for quite some time that whales are descendants of land mammals.
Some interesting evidence to support this theory has recently been found.
In Egypt, fossils have been found of a forty-million-year-old whale leg,
kneecap, ankle, footbones, and toes. It appears from the fossil evidence that
the bones were not very strong and not very large in comparison to the size of
the whale.
Based on this fossil evidence, the following evolutionary path has been
hypothesized. As the whale began its evolution toward the water, its legs
weakened and decreased in size. Then, during its millions of years in the
water, the legs slowly disappeared, leaving only the front flippers today.

1. The main idea of this passage is that
a. there isevidence that whales may have descended from land mammals.
b. whales have not evolved very much over the last millions of years.
c. whales are mammals and not fish
d.numerous whale fossils have been found in the world’s oceans


2. All of the following are true abooceanales, EXCEPT that

When the typewriter was first invented, its keys were arranged
alphabetically. This made the keys easy to find. However, this arrangement
also caused the bars of the machine to jam, or get stuck.
To solve this problem, a new letter arrangement was introduced by
Christopher Latham Scholes in 1872. His system, the standard keyboard
system, is still used on keyboards today. He arranged the letters in such a way
that the bars hit the inked ribbon from opposite directions as much as possible.
This resulted in far less jamming than had occurred with the alphabetical models.
3. The main topic this passage is
a.why the keys stick on today’s typewriter
b. a problem and solution concerning the early typewriter
c.how to write a letter on the typewriter
d.the invention of the typewriter


4. According to the passage, on the first typewriters
a.the keys were in alphabetical order
b.Scholes’s system worked quite well.
c.the bars on the machine never jammed.
d.the keys were hard to find
