Practice Test Four 345<br />

Directions: The following passage is an early draft of an essay. Some parts of <strong>the</strong> passage need to be rewritten.<br />

Read <strong>the</strong> passage and select <strong>the</strong> best answer <strong>for</strong> each question that follows. Some questions are about particular<br />

sentences or parts of sentences and ask you to improve sentence structure or word choice. O<strong>the</strong>r questions ask<br />

you to consider organization and development. In choosing answers, follow <strong>the</strong> conventions of standard written<br />

English.<br />

Questions 30-35 are based on <strong>the</strong> following passage.<br />

(1) Scientists working in <strong>the</strong> Arctic and Antarctic<br />

have been trying to figure out if our world is getting<br />

warmer. (2) However, research on global warming<br />

could not be accomplished without <strong>the</strong> aid of a tough<br />

and reliable icebreaker, a tool which has only been<br />

around <strong>for</strong> slightly more than a hundred years.<br />

(3) Icebreakers do not "push" <strong>the</strong> thick expanses of<br />

ice, contrary to what most people believe. (4) They are<br />

instead crushed under <strong>the</strong> weight of <strong>the</strong> ship's bow,<br />

which is pushed through by powerful engines. (5) The<br />

ship <strong>the</strong>n reverses, powers ahead, and runs up onto <strong>the</strong><br />

ice again. (6) So that <strong>the</strong> vessel clears a path <strong>for</strong> itself.<br />

(7) What is time-consuming about this is that <strong>the</strong> ice<br />

can be up to sixteen feet thick.<br />

(8) Ra<strong>the</strong>r, <strong>the</strong>ir ability to break through thick ice<br />

is due to several unique design features: <strong>the</strong> bow, <strong>the</strong><br />

hull, and <strong>the</strong> propulsion system. (9) Since a typical<br />

ice breaker may only spend 25 percent of its time in<br />

ice, it must per<strong>for</strong>m well in open water, too. (10) For<br />

example, <strong>the</strong> bow of an ice breaker does not go straight<br />

down, it is sloping at a 30 degree angle.<br />

(11) Aside from <strong>the</strong>ir role in helping scientists study<br />

global warming, ice breakers have o<strong>the</strong>r uses. (12) They<br />

are used to conduct fundamental research to understand<br />

<strong>the</strong> nature and characteristics of snow, ice, frozen<br />

ground, and o<strong>the</strong>r materials in cold regions.<br />

30. In context, what is <strong>the</strong> best way to deal with<br />

sentence 4 (reproduced below)?<br />

They are instead crushed under <strong>the</strong> weight of <strong>the</strong><br />

ship's bow, which is pushed through by powerful<br />

engines.<br />

(A) Delete it.<br />

(B) Switch it with sentence 5.<br />

(C) Change They are to The ice is.<br />

(D) Change which to that.<br />

(E) Change is pushed to are pushed.<br />

31. What is <strong>the</strong> best way to revise <strong>the</strong> underlined<br />

portion of sentences 5 and 6 (reproduced below)?<br />

The ship <strong>the</strong>n reverses, powers ahead, and runs up<br />

onto <strong>the</strong> ice again. So that <strong>the</strong> vessel clears a path <strong>for</strong><br />

itself.<br />

(A) again, by which <strong>the</strong> vessel clears<br />

(B) again, because <strong>the</strong> vessel clears<br />

(C) again, and <strong>the</strong> vessel, clearing<br />

(D) again, so that <strong>the</strong> vessel clears<br />

(E) ice, <strong>the</strong> vessel clears<br />
