17. 4<br />

Difficulty: High<br />

4x =80<br />

X=20<br />

Strategic Advice: Draw <strong>the</strong> line y = 3 and count how many<br />

times this line intersects <strong>the</strong> graph of <strong>the</strong> function.<br />

Getting to <strong>the</strong> Answer:<br />

18. 6.06<br />

Difficulty: High<br />

Strategic Advice: A line tangent to a circle <strong>for</strong>ms a right<br />

angle with a diameter of <strong>the</strong> circle at <strong>the</strong> point of tangency.<br />

Also, remember that a right triangle with short leg s and<br />

hypotenuse 2s has long leg s\/3.<br />

Getting to <strong>the</strong> Answer:<br />

DH = hypotenuse = 7<br />

- 1 7<br />

EH = 2 <strong>the</strong> diameter = 2<br />

- 7\13<br />

SECTION 6<br />

1. B<br />

Difficulty: Low<br />

Make sure items in a comparative structure are logical.<br />

As written, <strong>the</strong> sentence is comparing pizzas to Guido's.<br />

Choice (B) fixes this error by adding a pronoun that<br />

refers back to pizzas. Choices (C) and (E) are fragments.<br />

Choice (D) does not address <strong>the</strong> error and introduces <strong>the</strong><br />

idiomatically incorrect better than like.<br />

2. B<br />

Difficulty: Low<br />

Although most idiom questions test preposition usage, some<br />

also test constructions that require <strong>the</strong> infinitive verb <strong>for</strong>m.<br />

In this context, <strong>the</strong> verb hopes requires <strong>the</strong> infinitive<br />

verb <strong>for</strong>m. Choice (B) makes <strong>the</strong> correction. Choice (C)<br />

incorrectly uses <strong>the</strong> pronoun it to refer to a person. Choices<br />

(D) and (E) are unnecessarily wordy.<br />

unnecessarily wordy. Choice (E) does not address <strong>the</strong> error.<br />

4. E<br />

Difficulty: Medium<br />

Comparative structures such as not only . .. but also require<br />

that <strong>the</strong> subjects of <strong>the</strong> comparison be presented in parallel<br />

<strong>for</strong>m.<br />

As written, this sentence violates <strong>the</strong> rules of parallel structure.<br />

Choice (E) corrects <strong>the</strong> error; none of <strong>the</strong> o<strong>the</strong>r answer<br />

choices do.<br />

5. A<br />

Difficulty: Medium<br />

Don't mistake complex sentence structure <strong>for</strong> a grammatical<br />

error.<br />

This sentence is correct as written. The modifying phrase<br />

who ore historically avid baseball fans correctly modifies<br />

Chicago residents, and although is <strong>the</strong> appropriate<br />

transition. Choice (B) misuses <strong>the</strong> semicolon splice, which<br />

is only correct when used to connect two independent<br />

clauses. Choices (C) and (E) introduce <strong>the</strong> passive voice<br />

unnecessarily. Choice (D) creates a sentence fragment.<br />

6. D<br />

Difficulty: Medium<br />

If a sentence in <strong>the</strong> passive voice can be easily reworded to<br />

use an active verb, <strong>the</strong> correct answer choice will do so.<br />

Choice (D) changes <strong>the</strong> passive UV rays ore prevented to <strong>the</strong><br />
