16. A
Difficulty: Medium
a=3[2b2 - 16b+32+-3b+ 12 +4]
a=3[2b2 -16b +32+-3b + 16]
a = 3 [2b2 - 19b + 48]
a= 6b2 - 57b + 144
Strategic Advice: This problem deals with the probability
that the fish has both characteristics, so multiply the
probability of having long fins (t) by the probability of
having a long tail ( t) . Even if you're not sure how to find
this probability, you can reason that it is less likely for the
fish to have both characteristics than to have just one
characteristic or the other. Therefore, the probability of the
fish having both characteristics must be less than t
(the probability that it has a long tail). This eliminates all
but (A) and (B). You can use this kind of logic to narrow
your choices down and increase your chance of guessing
correctly on many problems.

SECTION 9
1. c
Difficulty: Medium
One way to correct a run-on sentence is to make one of the
independent clauses subordinate.
As written, this sentence is a run-on. Choice (C) corrects this
by making the second clause subordinate. Choices (B) and
(D) correct the error but are unnecessarily wordy. Choice (E)
does not address the error.
2. B
Difficulty: High
Unless context makes it clear that more than one time
frame is referred to, verb tenses within a sentence should
remain consistent.
The first clause of the sentence is in the past tense, so
the underlined verb should be also. Choice (B) makes
the correction. Choice (C) introduces the passive voice
unnecessarily, and the plural verb are does not agree with
the singular noun hour. Choice (D) fails to make it clear
whether they refers to programs or languages. Choice (E)
is unnecessarily wordy.
3. c
Difficulty: Medium
Make sure transition words properly relate the ideas in the sentence.
Here, the transition word as suggests a cause-and-effect
relationship between the clauses that is inappropriate in the
context. Choice (C) logically relates the clauses. In (B), the
Aztecs are what is among Switzerland's most popular exports.
Choice (D) does not address the error. Choice (E) uses
incorrect grammatical structure.
4. D
Difficulty: Medium
Pronoun uses should remain consistent within a sentence.
This sentence starts out using the third-person singular
pronoun someone, then switches to the second-person
pronoun you. Choice (D) corrects this error with the third
person pronouns he and she. The pronoun it in (B) is
incorrect when referring to people. Choice (C) does not
address the pronoun error. Choice (E) incorrectly uses a
plural pronoun with a singular antecedent.
5. B
Difficulty: High
A possessive noun functions as an adjective within a sentence.
As written, this sentence says that it was hit songs, not the
Beach Boys themselves, that were born and raised on the
coast of California. Choices (B) and (E) correctly place the
Beach Boys directly after the clause; however, (E) creates
a sentence fragment. In (C), the opening phrase modifies
celebration; in (D), it modifies life.
6. c
Difficulty: Medium
Ambiguous pronouns will always be wrong on the SAT;
pronouns must refer to clear and specific antecedents.
As written, this sentence does not make it clear whether
the pronoun he means Professor Schonle or his son.
Choice (C) eliminates the ambiguous pronoun. Choice (B)
eliminates the ambiguous pronoun but makes the sentence
unnecessarily wordy. Choice (D) does not address the error.
