16. 103<br />

Difficulty: Low<br />

Strategic Advice: The median is <strong>the</strong> middle number. Since<br />

<strong>the</strong>re is an odd number of consecutive integers, <strong>the</strong>re is<br />

one integer in <strong>the</strong> middle and <strong>the</strong> same number of integers<br />

above and below that middle integer. You want to figure out<br />

how many numbers are above <strong>the</strong> middle.<br />

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

Subtract 1 from <strong>the</strong> number of integers:<br />

97 - 1=96<br />

Divide this by 2 to find out how many integers are above<br />

<strong>the</strong> median:<br />

96<br />

=<br />

48<br />

2<br />

Add this value to <strong>the</strong> median to calculate <strong>the</strong> largest<br />

number: 55 + 48 = 103.<br />

17. 2<br />

Difficulty: Medium<br />

Strategic Advice: Picking Numbers will get you to <strong>the</strong><br />

answer quickly. Start with a simple number that yields a<br />

remainder of 3 when you divide by 4, such as 7.<br />

18. 9<br />

Difficulty: Medium<br />

Strategic Advice: Since all of <strong>the</strong> points lie on <strong>the</strong> same<br />

line, <strong>the</strong> squares increase by <strong>the</strong> same ratio (<strong>the</strong> slope of<br />

<strong>the</strong> line). Figure out <strong>the</strong> value of <strong>the</strong> increase of <strong>the</strong> side of<br />

<strong>the</strong> square, <strong>the</strong>n set up a ratio with <strong>the</strong> complete sides of<br />

<strong>the</strong> squares.<br />

SECTION 5<br />

l. B<br />

Difficulty: Medium<br />

A descriptive phrase or clause must be closely followed by<br />

<strong>the</strong> noun it is intended to modify. Since Julie is <strong>the</strong> one who<br />

was shopping <strong>for</strong> a birthday present, no noun or pronoun<br />

should appear between <strong>the</strong> descriptive clause and her<br />

name. Choice (B) puts Julie directly after <strong>the</strong> clause. Choice<br />

(C) is unnecessarily wordy, and <strong>the</strong> possessive Julie 's is an<br />

adjective, not a noun. In (D) and (E), <strong>the</strong> clearance sale is<br />

doing <strong>the</strong> shopping; additionally, both introduce <strong>the</strong> passive<br />

voice unnecessarily.<br />

2. B<br />

Difficulty: Medium<br />

Style errors may be difficult to spot; plug in answer choices<br />

methodically to see if a more concise version of <strong>the</strong><br />

selection is included. While this is not technically a run-on<br />

sentence, combining <strong>the</strong> two clauses with and does not
