• Was the seminar the actual cause of the improved level of contentment among the

participants from Maxtech? (The answer might depend on how much time has

passed since the seminar, whether Maxtech’s participants have the same jobs as

before, and whether the seminar is designed to help workers become more content

to begin with.)

• Are the claims by Maxtech’s employees credible? (Perhaps they felt pressure to

exaggerate the benefits of the seminar or falsely report improvement in order to

take time off from work to enroll again in the seminar.)

• Might the argument assume that all other conditions remain unchanged?

(Overall productivity of the economy’s private sector depends also on many

extrinsic factors having nothing to do with the benefits of these types of

seminars.)

1 The correct answer is (A)

Propo-nents of urban development would oppose the idea that urban devel-opment fosters crime So the

“mechanism” referred to in the

sen-tence might either function, react, or

emerge, but not disappear or fail.

The sentence cites anonymity and population density as examples of the second missing word It makes

no sense to characterize these examples either as cities or

criminals, and of the two remaining

choices, choice (B) is weaker than choice (A) on two counts First, the sentence as a whole does not strongly support the use of the word

react; what the mechanisms might

react to is neither stated nor inferred

in the sentence Second, while a trait

is properly referred to as “found,” a factor is not (factors typically “come into play”) So choice (B) makes for

4 The correct answer is (B)

Some-thing AUSTERE is “severe, harsh, or forbidding”—the opposite of for-giving.

5 The correct answer is (E) This is

an “inherent function” analogy The function of a TEACHER is to provide INSTRUCTION for another;

simi-larly, the function of a guard is to provide protection for another As for

choice (D), although the “function” of

a student might be said to learn, it is not to provide learning for another

So choice (D) is not as strong an analogy as choice (E)

6 The correct answer is (E) The

two parts of the sentence paraphrase the same idea Therefore, the first blank should correspond to the idea

of “the things they most deeply cherish” in the second half of the

sen-PART VI: Five Practice Tests 428

types of components that together

make a WATCH operate; similarly, a

manager is one of many types of

workers who contribute to the

operation of a bureaucracy (a large,

structured organization)

9 The correct answer is (B) This is

one form of an “operates against”

analogy To QUELL is to suppress or

put down, an act that eliminates an

UPRISING; similarly, to quench is to

completely satisfy a thirst, an act

that eliminates it

10 The correct answer is (A) This is

a “form of ” (degree or extent)

analogy PIVOTAL means “extremely

IMPORTANT,” just as draconian

means “extremely stern.” The

analogy is based on degree

11 The correct answer is (C) As the

passage indicates,

dendrochrono-logical studies involve analyzing tree

rings Although the wood from trees

might have been used for creating

items which are now considered

archeological artifacts, the author

does not indicate explicitly that tree

rings are studied for the purpose of

dating such artifacts

12 The correct answer is (B) In the

second paragraph, the author

men-tions choices (A), (C), (D), and (E) as

problems with radiocarbon dating

Nowhere in the passage, however,

does the author mention any

problem involving sample

deterio-ration

13 The correct answer is (E).

RANCOR is a “feeling of hostility or

antagonism toward another”;

affection is a “feeling of fondness

toward another.”

14 The correct answer is (D) The

best word for the second blank must suggest how the articles about

“medical problems” related to the

“heartwarming stories” that first appeared It makes sense that

sobering accounts would counter-balance heartwarming stores.

15 The correct answer is (B) Most of

the passage—the entire second and third paragraphs—is concerned with examining the factors affecting the climate of various portions of the

Andean cordillera The first

para-graph provides a framework for this discussion by describing the climate and topography of the various regions

16 The correct answer is (A) The

high-altitude plateaus are called

explicitly that the soil fertility in the

northern altiplano is generally good.

17 The correct answer is (E) The

passage points out that while air temperature generally decreases as altitude increases, “variability of mountain topography”—i.e., dra-matic changes in elevation—makes

it difficult to determine temperature

in any given spot from widely spaced measurements It can be reasonably inferred from this information that

an unexpected temperature would probably be the result of unexpected altitude

18 The correct answer is (D) The

only discussion of mountain sym-metry is in the first paragraph, which mentions the symmetry in climate between the east and west flanks of the Northern Andes moun-tains No mention is made anywhere

Trang 8

in the passage of any symmetry with respect to the Central Andes moun-tains On the other hand, choices (A), (B), (C), and (E) are all mentioned in the passage as factors affecting the

climate of the Central Andes

cor-dillera.

19 The correct answer is (A) Skin

that is WAN is pale, or lacking color;

skin that is flushed is characterized

by glowing or a reddish color (as when a person blushes)

20 The correct answer is (B) This is

a “result of” (process and product) analogy When engaging in the art of SCULPTURE, especially wood sculpture, the artist produces a SHAVING, which is a byproduct of the sculpting process When a person

commits a burglary, the burglar’s

byproduct Another key to this analogy is that in neither case is the result the actor’s main objective or intention

21 The correct answer is (C) The

word “yet,” which begins the sen-tence’s second clause, tells you to look for a contrast between the two parts of the sentence The missing word must suggest a difference between the two writers rather than

as strong an analogy—a loan,

although it’s one possible reason to

engage a bank, is not an award.

23 The correct answer is (C) This is

a “defining characteristic” analogy A person who is CIRCUMSPECT (cau-tious, wary, guarded, or watchful) is

by definition characterized by VIGI-LANCE (watchfulness); similarly, a

person who is ardent (zealous or

eager) is by definition characterized

by enthusiasm.

24 The correct answer is (i) integral and (ii) history or tradition The

idea of the first sentence is that his-toric buildings that cannot be made safe must often be demolished, because structural safety is essential

(or integral) when it comes to a

building used by the general public The idea of the third sentence is that

a building’s historic value (expressed

more artfully, history or tradition)

need not always be sacrificed for the sake of making the building safe for the public

25 The correct answer is (A) In the

preceding sentence, the author asserts that Turner’s and Jordan’s descriptions of restorationist ac-tivities “do not cohere well with the community participation model.” By

Trang 9

program, which the author then

elu-cidates in the second paragraph

27 The correct answer is (C) The

phrase “at least as much as” sets up

comparison between theoretical and

the first missing word This word

should express an idea that opposes

theoretical Choices (A), (C), and (D)

are the only viable choices The

tran-sitional phrase “in that” signals that

the first missing word should be a

synonym for detect This narrows the

choices to (A) and (C) Now, consider

the second word in each of these two

answer choices Disprove runs

con-trary to the intended meaning of the

sentence as a whole Thus, choice (C)

provides the best completion

28 The correct answer is (A) This is

a “place or environment for” analogy

You dig a QUARRY, or excavation pit, where raw materials such as MARBLE are located for the purpose

of extracting the materials

Simi-larly, you construct a well where oil

is located for the purpose of

extracting the oil.

29 The correct answer is (C) This is

a “possible use of ” analogy A SNORKEL is an apparatus designed

to aid in DIVING, but it is not essential for that activity; similarly,

a blade is an apparatus designed to aid skating, but it is not essential for

that activity

30 The correct answer is (B)

EXAC-ERBATE has two common mean-ings: “provoke” and “intensify or

heighten.” To lessen in degree is to do

the opposite of intensify

1 The correct answer is (C) To

determine Quantity A, substitute the

number 2 for a and for b in the

cen-tered equation:

(2 + 2)(2 2 2) = (4)(0) = 0 Follow the same procedure for the quantity in Column B:

(22 + [22])(22 2 [22]) = (24)(0) = 0 The quantities in both columns equal zero (0)

2 The correct answer is (A) For any

fractional number between zero (0) and 1, the number is less than its square root, which in turn is less than its cube root

3 The correct answer is (A) A

circle’s circumference is pd—the

product of p (a bit greater than 3.1) and the circle’s diameter If AB and

CD were each as large as possible, they would each equal the circle’s diameter Three times this length is

to a multiple of 3 is also a multiple

of 3

5 The correct answer is (A) In

choice (A), unequal quantities are subtracted from equal quantities The differences are unequal, but the inequality is reversed because unequal numbers are being sub-tracted from rather than added to the equal numbers

6 The correct answer is (D).

Without knowing either interest rate, it is impossible to compute either quantity in order to make the comparison

7 The correct answer is (C) There

are 2 prime numbers between 10 and 15: 11 and 13 The integer 33 has 2 prime factors: 3 and 11

8 The correct answer is (A) First,

isolate y by dividing all terms by 3:
