Practice Test Three Answers and Explanations
escaping force. Choice (E) is out of scope; this relates to
another meaning of the word.
23. D
Difficulty: Medium
Locate the quote and search the relevant text around it to
help in making your prediction.
In the referenced sentence, the author tells us that Einstein
commented that one could reasonably expect the world
to be in no way graspable through thinking. But in the
next sentence, the author states that a full understanding is
achievable. Your prediction should reflect a sense of wonder
at this concept.
Choice (A) is out of scope; the author does not talk about
the effect of physical laws on chaos. Choice (B) is a
distortion; though he discusses Einstein's influence, the
author is not using this quote to do so. Choice (C) is an
opposite; this quote implies that Einstein treasured the
beauty of physics. Choice (D) fits well. Choice (E) is out of
scope; there is nothing to imply this.
24. B
Difficulty: Medium
With any passage, your notes should include a prediction of
the author's purpose or main idea. Your work on questions
like these will already be mostly done.
The author spends most of his time discussing how an
understanding of physics adds to his appreciation of
perceiving beauty; this would be a good prediction.
Choice (A) is a misused detail; this is only discussed in
the first paragraph. Choice (B) fits your prediction very
well. Choice (C) is a misused detail; this is mentioned
only briefly. Choice (D) is out of scope; the author never
discusses Einstein 's achievements. Choice (E) is out of
scope; the author does not spend much time discussing
physical laws.

1. c
Difficulty: Low
Strategic Advice: Translate the words into an algebraic
expression, paying close attention to the exponents and the
order of operations.
Getting to the Answer:
Take it step-by-step:
"three-fourths of the cube of a"
x a3
4
"plus the value of b divided by the square of c"
3 + ..!?_
4 c2
You have to be very careful here to follow the order of
operations. Only b is divided by c, not the sum of a3 and b.
4
"equals a"
a3 +
..!?_ =a
4 c2
Choice (C) is correct.
( 3 3a3 )
Note that 4
a3 = 4·
2. B
Difficulty: Low
Strategic Advice: When a question charges different rates
in a problem, figure out how much is charged at each rate
and add the totals together.
Getting to the Answer:
The rental would have 7 days charged at $40, and 3 days
charged at $35. Therefore, the first 7 days would cost 7 x
$40 = $280. The next 3 days would cost 3 x $35 = $105.
The total is $280 + $105 = $385.
3. D
Difficulty: Low
Strategic Advice: If the number of tulips, n, varies directly
with Kim's age, a, their relationship can be written as n = ka,
where k is a constant. You can use the given set of values to
find k, then use that to find the value of n when a= 25.
Getting to the Answer:
16 =k(lO)
k= J.§. =
10 5
n = (25) =40
