Directions for Problem Solving Questions: (These directions will appear on your
screen before your first Problem Solving question.)
Solve this problem and indicate the best of the answer choices given.
Numbers: All numbers used are real numbers.
Figures: A figure accompanying a Problem Solving question is intended to provide infor-
mation useful in solving the problem. Figures are drawn as accurately as possible EXCEPT
when it is stated in a specific problem that its figure is not drawn to scale. Straight lines
may sometimes appear jagged. All figures lie on a plane unless otherwise indicated.

Directions for Data Sufficiency Questions: (These directions will appear on your
screen before your first Data Sufficiency question.)
This Data Sufficiency problem consists of a question and two statements, labeled (1) and
(2), in which certain data are given. You have to decide whether the data given in the
statements are sufficient for answering the question. Using the data given in the
statements plus your knowledge of mathematics and everyday facts (such as the
number of days in July or the meaning of counterclockwise), you must indicate whether:
(A) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to
answer the question asked;
(B) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to
answer the question asked;
(C) BOTH statements (1) and (2) TOGETHER are sufficient to answer the
question asked, but NEITHER statement ALONE is sufficient;
(D) EACH statement ALONE is sufficient to answer the question asked;
(E) Statements (1) and (2) TOGETHER are NOT sufficient to answer the question
asked, and additional data specific to the problem are needed.
Numbers: All numbers used are real numbers.
Figures: A figure accompanying a Data Sufficiency problem will conform to the
information given in the question, but will not necessarily conform to the additional
information in statements (1) and (2).


Lines shown as straight can be assumed to be straight and lines that appear jagged can
also be assumed to be straight.
You may assume that positions of points, angles, regions, etc., exist in the order shown
and that angle measures are greater than zero.
All figures lie in a plane unless otherwise indicated.
Note: In Data Sufficiency problems that ask you for the value of a quantity, the data
given in the statements are sufficient only when it is possible to determine exactly one
numerical value for the quantity.

3. A reliable survey indicates that
college graduates change employers
four times on average during the
first ten years after college gradua-
tion. Therefore, in order to avoid
employee turnover, business adminis-
trators in charge of hiring new
employees should favor job applicants
who obtained college degrees at least
ten years earlier.
The advice about how to avoid
employee turnover rests on which of
the following assumptions?
(A) Employee turnover among
businesses that hire employees

without college degrees is
greater than among businesses
that hire only employees with
college degrees.
(B) Job changes within the same
company are less common than
job changes from one employer
to another.
(C) Employees who graduated from
college at least ten years ago
change employers less fre-
quently on average than other
employees.
(D) Most employees who leave their
jobs do so upon either request
or demand of their employers
rather than by their own
initiative.
(E) The survey excluded college
graduates who interrupted their
vocational careers to pursue
advanced academic degrees.
4. Although residents of the north-
central region of the United States
are not known to have any accent,

5. Driving excessively fast has been
demonstrated to decrease the number
of miles one can drive per gallon of
fuel. Gary has recently been experi-
encing a decrease in mileage per
gallon of fuel while driving his car.
This clearly proves that Gary has
been driving excessively fast lately.
Which of the following statements, if
true, would most seriously weaken
the conclusion about Gary’s driving?
(A) Recently Gary’s speedometer
has been indicating the speed of
his car as lower than the car’s
actual speed.
(B) Recently Gary has been driving
more miles per day on average
than before he began experienc-
ing a decrease in fuel mileage.
(C) Other tests have shown that a
car’s speed affects fuel mileage
more than any other single factor.

(D) Before Gary began driving
excessively fast his speedometer
over-represented his car’s
actual speed.
(E) Recently the tires on Gary’s car
have been losing air pressure,
and low tire air pressure is
known to lower fuel mileage.

6. Expensive television advertising
campaigns clearly help political
candidates win elections, as
evidenced by the fact that, in most
political elections, the candidate
with the most campaign money
ultimately wins.
Which of the following, if true,
would provide most support for the
argument above?
(A) Endorsements from minor
political office-holders generally
have no effect on a candidate’s
chances of winning an election.
(B) In most cases, candidates who
currently hold the office for
which they seek re-election

have more available campaign
money than their competitors.
(C) Expensive television advertising
campaigns are waged most
frequently by candidates who
have more available campaign
money than their competitors.
(D) When it comes to choosing
among candidates, the voting
public tends to disregard how a
candidate is portrayed in
television advertisements.
(E) Nearly any political candidate
can afford to wage some type of
television advertising campaign.
QUESTIONS 7–9 ARE BASED ON THE
FOLLOWING PASSAGE:
Line The twentieth-century discovery of
Archaeans, which did not fit into the
kingdom classification scheme for
biological life, led to the creation of the
domain classification level, above the
kingdom level. This new level included
the new domain Archaean. Prior to the
discovery of Archaeans, it had been
generally accepted that no life could
exist in temperatures much hotter
than 60 degrees centigrade. This limit
was set because it was thought that
the molecular integrity of vital cellular

components could not be maintained
beyond such temperatures. The
thermal capacity of cellular life, it was
believed, was a fixture across all
biological organisms. Archaeans, in
recent decades, have repeatedly
demonstrated that the previously
maintained thermal threshold for life
was far too low. So-called extremophilic
Archaeans have been discovered to
thrive in temperatures as high as 160
degrees centigrade. Such discoveries
have required a broadening of biology’s
conceptions concerning what environ-
ments are hospitable to life.
7. The author of the passage implies
that extremophilic Archaeans
(A) are able to maintain molecular
integrity of cellular components
past what was formerly ac-
cepted as the thermal threshold
of life.
(B) have been known to exist in
moderate environments for
some years, but their extremo-
philic properties have only
recently been discovered.
(C) are able to live and thrive in
temperatures higher than 160
degrees centigrade.

(D) were responsible for the
development of a distinct
kingdom in the classification
scheme for biological life.
(E) are the oldest known form of
multi-cellular biologic life.
8. The passage’s author suggests that
the “thermal threshold” (line 21) is
(A) the thermal capacity of extre-
mophiles.
(B) the critical point temperature at
which the metabolic pathways
of extremophiles become
functional.
(C) an environmental extremity
indicator.
(D) the temperature at which the
molecular integrity of cellular
components of an organism are
compromised.
(E) a biological constant across all
of nature.
