Practice Test Eleven Answers and Explanations
Questions 23-24
In this short passage, the author says that if a shark did
attack a girl in the Hudson, it was most likely a bull shark,
which, unlike great white and tiger sharks, can live in rivers.
23. D
Difficulty: Low
What is needed to verify something as a truth? The author
states that she was unable to prove the truth of the shark
story because of a lack of a specific type of evidence. What
choice best describes the type of evidence she needed?
Choice (A) is distortion; the shark story itself is hearsay;
the author wants to back it up with solid evidence. Choice
(B) is an irrelevant detail; confidential makes no sense in
context. Choice (C) is distortion; brutal is synonymous with
hard when it used to describe toughness or insensitivity,
but it makes no sense as applied in this context. Choice (0)
should match your prediction. Choice (E) is an opposite;
the information the author presents about bull sharks could
be considered theoretical evidence, but here the author
says we need convincing evidence that a great white shark
survived in a creek and attacked the girl.
24. E
Difficulty: Low
What is it about the bull shark that makes it different from
the two other types of sharks mentioned in the passage? In
the passage, the author states that Unlike ... the great white
and tiger sharks, bull sharks can survive in bodies of water
with lower levels of salinity than the ocean. Look for the
answer that best rephrases this detail to fit the question.
Choice (A) is distortion; the passage states that tiger sharks
are equally ferocious as great white and bull sharks. Choice
(B) is out of scope; a tiger shark's size is never mentioned
in the passage. Choice (C) is an irrelevant detail; the girl was
supposedly attacked in a creek, not the Mississippi. Choice
(0) is distortion; the information about the bull shark proves
that the events in the story could have happened. Choice
(E) is a good match for your prediction.
SECTION 6
1. c
Difficulty: Low
Strategic Advice: Sometimes even questions of low
difficulty contain traps for the unwary. Here, notice that
you're asked, not for d, but for 2d.
Getting to the Answer:
3d= 10
d=J.Q
3
2d= 20 = 6-
3 3
2. B
Difficulty: Low
Strategic Advice: Notice how much or how little a question
constrains the range of numbers you're dealing with. In
this case, when you think of a number that satisfies the
requirements of the question stem, do you notice how
unconstrained you are? All these numbers work: 1, 7, 17,
71, 111, 777, etc.
Getting to the Answer:
The number 1 rules out every choice but the answer.
3. A
Difficulty: Low
Strategic Advice: If you're unsure of how to handle
problems with square roots of variables, Backsolve or use
your given answers. But as you'll see below, the algebraic
solution isn't prohibitively complicated.
Getting to the Answer:
9Vx =9
vX= 2. = 1
9
x= l
4. E
Difficulty: Medium
Strategic Advice: Break complex processes down into
separate steps. Here, first determine k; then use that value
to find y.
