Practice Test Two Answers an d Exp l anations<br />

Choice (A) indicates an inappropriate cause-and-effect<br />

relationship between <strong>the</strong> sentence's two clauses. Choice<br />

(C) is incorrect with <strong>the</strong> singular subject microwave cooking.<br />

Choice (D) introduces an inconsistent verb tense. Choice<br />

(E) incorrectly replaces <strong>the</strong> noun effect with <strong>the</strong> verb affect.<br />

33. E<br />

Difficu l ty: Medium<br />

For questions that raise a number of issues, a methodical<br />

check of <strong>the</strong> choices is best.<br />

The answer choices here cover a number of issues, so it's<br />

best to check each in turn. The words on <strong>the</strong> contrary in<br />

(A) would have to be followed by a sentence that contrasts<br />

with <strong>the</strong> in<strong>for</strong>mation in <strong>the</strong> previous sentence, which is not<br />

<strong>the</strong> case here. Choice (B) causes a grammatical error; a<br />

number can decrease, but white blood cells cannot. Without<br />

(C), <strong>the</strong> logic of <strong>the</strong> sentence is lost. Choice (D) makes<br />

incorrect use of <strong>the</strong> semicolon splice, which is only correct<br />

when used to combine two independent clauses. Since<br />

sentence 7 continues <strong>the</strong> discussion of a study that was<br />

completed in <strong>the</strong> past, <strong>the</strong> verbs should be in <strong>the</strong> past<br />

tense; (E) is <strong>the</strong> correct choice here.<br />

34. c<br />

Difficu l ty: Medium<br />

Some structures are only correct when used toge<strong>the</strong>r. Not<br />

only . .. but also is one such construction. Only (C) correctly<br />

completes <strong>the</strong> construction. Additionally, (B) misuses <strong>the</strong><br />

semicolon splice; since <strong>the</strong> first clause does not express a<br />

complete thought, it's not independent.<br />

35. c<br />

Difficu l ty: Medium<br />

A verb must agree in number with its subject noun,<br />

which may not be <strong>the</strong> noun closest to it in <strong>the</strong> sentence.<br />

Although <strong>the</strong> singular noun community is closer to<br />

<strong>the</strong> verb phrase has concluded, its subject is actually<br />

<strong>the</strong> plural experts; (C) is <strong>the</strong> needed revision. In (B),<br />

significantly modifies has concluded, so <strong>the</strong> adverb <strong>for</strong>m<br />

is correct. Choice (D) agrees with its plural subject o<strong>the</strong>rs.<br />

Choice (E) introduces a verb tense that is incorrect in<br />

context.<br />

1. c<br />

Difficu l ty: Low<br />

Strategic A d vice: There are two solutions to an absolute<br />

value equation. Find <strong>the</strong> first by ignoring <strong>the</strong> absolute value<br />

sign and solving as normal. You can <strong>the</strong>n find <strong>the</strong> second<br />

equation by multiplying everything inside <strong>the</strong> absolute value<br />

sign by (- 1) and <strong>the</strong>n solving <strong>the</strong> equation that results.<br />

Getting to t h e Answer:<br />

5x + 15 = 10 or -5x -15 = 10<br />

5x = -5 or -5x = 25<br />

so x=-1 or x=-5<br />

2. D<br />

Difficu l ty: Low<br />

Strategic A d vice: Don't do excess math. All you need to know<br />

to solve this problem is how to get <strong>the</strong> decimal point to move.<br />

Getting to t h e Answer:<br />

(0.001 3)x = 0.013<br />

0.013<br />

x = 0.0013<br />

= 10<br />

3. B<br />

Difficu l ty: Low<br />

Strategic A d vice: Use b = 2 to solve <strong>for</strong> a in <strong>the</strong> first<br />

equation. Then solve <strong>for</strong> c in <strong>the</strong> second equation.<br />

Getting to t h e Answer:<br />

First equation:<br />

2- =8<br />

2<br />

a= 16<br />

Second equation:<br />

J_§_ = 4<br />

c<br />

16= 4c<br />

C=4<br />

Difficu l ty: Medium<br />

Strategic A d vice: On geometry word problems, draw a<br />

rough sketch of what <strong>the</strong> figure could look like. This will
