CHAPTER 16 / PRACTICE TEST 3 763

15.C Lines 49–50 mention that seismologists
missed predictingthe Tangshan earthquake and that
over 250,000 people died. This was far worse than the
Haicheng earthquake, which was successfully pre-
dicted,so that many lives were saved.

16.D The word “evacuation” in line 46 is placed in
quotations to indicate that it is not being used in the
traditional sense. The task of evacuating a population
from a natural disaster does not typically involve
showing movies, so doing so is unconventional.

17.C Lines 7–8 say that one of the missionaries who
met the ship took us under his wing.

18.E Saying that he could hardly believe that we
were really restored to himis like saying he couldn’t be-
lieve that we were returned to him.

19.B The narrator states that she could use tools as

well as [her] brothers did(lines 20–21), that her first

childhood friendship was with a male ship-builder

next door, and that she was eager and able to work

with the ship-builders around her. Thus, she conveys

a clear sense that she considers herself the equal of

the males in her life.

20.D The author was emancipated from her con-
fining clothing so that she could work with tools, such
as her hatchet, in the shipyard.

21.C The big movements of the dayrefer to the
changes in culture and civilization(line 43).

22.A Choice II is supported by lines 38–40, which
say that we had around us the fine flower of New Eng-
land civilization,as opposed to Michigan, which the
author characterizes as the wilderness(line 45). The
passage does not suggest that New England had finer
gardens or humbler citizens than Michigan had.

23.D The author describes the move to Michigan as
a complete upheaval(lines 37–38), and an unwelcome
move from the fine flower of New England civilization
(lines 39–40), thereby suggesting that she resents the
move. She conveys no sign of bewilderment, fear, or
awe in this passage, since she describes the move with
insight and equanimity.

24.A The passage says that the sisters were so
pained by(the lumber wagon’s) appearance that we re-
fused to ride in it(lines 55–56) and that they wanted
to look as if we had no association with it(lines 57–58).

1.D 4 x+ 5 = 20

Add 3: 4 x+ 8 = 23

(Chapter 8, Lesson 1: Solving Equations)

2.C First find out how many cups are in 3 pints.

Set up a ratio:

Cross-multiply: x=6 cups

Set up a ratio to solve for servings:

Cross-multiply:^1 ⁄ 3 x= 6

Divide by^1 ⁄ 3 : x= 18

(Chapter 7, Lesson 4: Ratios and Proportions)

3.A Since the angle shown is a right angle, the arc

represents^1 ⁄ 4 of the circumference.

length of arc =^1 ⁄ 4 (2πr)

Substitute 4 for r: length of arc =^1 ⁄ 4 (2π(4))

Simplify: length of arc = 2 π

(Chapter 10, Lesson 8: Circles)

4.C This question tests your understanding of 30°-

60 °-90°triangles. The hypotenuse, which corresponds

to 2x,is 14. This means that the base is x=7. The

height is therefore x =7.

(Chapter 10, Lesson 3: The Pythagorean Theorem)

5.A Given that ∇x= 3 x−3, find ∇7.

∇ 7 = 3 x− 3

Plug in 7 for x: 3(7) − 3 = 18

Find ∇3: ∇ 3 = 3 x− 3

Plug in 3 for x: 3(3) − 3 = 6

Be careful not to pick answer choice (B) ∇3, because

∇ 3 =3(3) − 3 =6, not 3. Answer choice (A) ∇2 is cor-

rect, because ∇ 2 =3(2) − 3 =3.
