GRE #13 Paper 2

Questions 1-3

Four lifeguards—F, G, H, and J—work at a
swimming pool that is open six days a week, Monday
through Saturday. Each day exactly one lifeguard is on
duty. The pool manager assigns guard duty each week
according to the following conditions:
Each lifeguard is assigned duty at least one day a
week.
No lifeguard is assigned duty on two consecutive
days.

1. If during one week F is assigned duty on Monday
and Saturday only, which of the following must be
true of the assignments for that week?
(A) One other lifeguard besides F is assigned duty
on two days.
(B) The lifeguard assigned duty on Wednesday
cannot be assigned duty on Friday.
(C) H is assigned duty on the day immediately
before the day on which G is assigned duty.
(D) Either G or H is assigned duty on Tuesday.
(E) Either H or J is assigned duty on Friday.

2. If during one week H is assigned duty on exactly
two days and G and J are each assigned duty on
days earlier in the week than the first day on
which H is assigned duty, H could be assigned
duty on which of the following pairs of days?
(A) Monday and Wednesday
(B) Tuesday and Thursday
(C) Tuesday and Saturday
(D) Wednesday and Saturday
(E) Friday and Saturday

3. If during one week F is assigned duty on Tuesday
and two other days, which of the following CAN-
NOT be true?
(A) F is assigned duty on Saturday.
(B) F and H are assigned duty on consecutive
days.
(C) G and H are assigned duty on consecutive
days.
(D) G and H are assigned duty on days before
Thursday.
(E) F is assigned duty on a day immediately
before a day on which G is assigned duty
and on a day immediately before a day on
which J is assigned duty.

4. Because of rules imposed by the Federal Drug
Administration restricting the sale of thalidomide,
many people who have trouble sleeping turn to
barbiturates. Yet each year barbiturate-alcohol
interactions cause the deaths of over a thousand
people who probably would have lived had they
used thalidomide instead of barbiturates, even
without changing their alcohol consumption.

Which of the following statements about thalido-
mide is best supported by the statements above?
(A) Thalidomide alone poses no serious health
risks.
(B) Barbiturates alone are more dangerous than
alcohol alone.
(C) Thalidomide is a more effective sleeping aid
than barbiturates.
(D) In some cases, the thalidomide-barbiturate
interaction would be less dangerous than
the barbiturate-alcohol interaction.
(E) In some cases, the thalidomide-alcohol interac-
tion would be less life-threatening than the
barbiturate-alcohol interaction.

5. Existing United States landfills are rapidly
approaching the limits of their capacity. Landfills
can leach toxins into groundwater, polluting it.
Instead of creating more landfills, solid-waste
managers should recycle as much trash as possible
and then incinerate the remainder. This will keep
future environmental damage to a minimum.

Which of the following is an assumption on which
the argument made above is based?
(A) Future landfills will pollute the environment
more than do those that already exist.
(B) After existing landfills reach the limit of their
capacity, they are closed, and the leaching of
toxins from these sites decreases.
(C) Reducing the volume of trash through recycling
will not lessen future environmental danger
unless the remaining trash is subsequently
incinerated.
(D) The environmental damage caused by the
proposed incineration of trash would be less
than that caused by the leaching of toxins
from new landfills into groundwater.
(E) No new landfill sites can be found in order to
increase the total capacity of landfills in the
United States

6. According to a 1980 survey, ten percent of all
United States citizens over the age of sixteen are
functionally illiterate. Therefore, if the projection
that there will be 250 million United States citizens
over sixteen in the year 2000 is correct, we project
that 25 million of these citizens will be functionally
illiterate.

Which of the following, if true, would most weaken
the conclusion drawn by the author of the passage
above?
(A) The percentage of high school graduates who
do not go on to college has grown steadily
over the past two decades.
(B) From 1975 to 1980 there was a three-percent
decrease in the rate of functional illiteracy
among United States citizens over the age
of sixteen.
(C) Many United States citizens included in the
1980 survey would also be included in a
survey conducted in the year 2000.
(D) Surveys that are improperly designed usually
provide inaccurate results.
(E) In 1980 sixty-five percent of all United States
citizens were over the age of sixteen.

Questions 20-22

Exactly seven people—Q, R, S, T, X, Y, and Z—
serve on an advisory board. Q, R, S, and T have
been elected to the board, and X, Y, and Z have been
appointed to the board. Three-person or four-person
panels are sometimes drawn from the board to study
proposals. Each panel must include at least one elected
and at least one appointed board member, but no panel
can consist of equal numbers of elected and appointed
members. Each panel is chaired by a person who is a
member of the group of board members (elected or
appointed) whose representatives are in the minority
on that panel. Any panel must also conform to the
following conditions:

panel.

panel.
T and Y cannot serve on a panel unless they serve
together.

panel.

23. On the basis of figures it complies, a citizens’ group
argues that congressional members of Party X
authorize the spending of more taxpayer dollars
than do congressional members of Party Y. The
group’s figures are based on an analysis of the
number of spending bills for which members of
Congress vote.

The figures of the citizens’ group will be unreliable
as a gauge of which party in Congress spends more
taxpayer dollars if which of the following is true?

equally, no matter how much taxpayer
money is involved in each bill.

including bills concerning the salaries of
members of Congress.

Congress are passed by Congress.

vote for are written and sponsored by
members of Party X.

24. Statistics over four consecutive years showed that
four percent more automobile accidents happened
in California during the week following the switch
to daylight saving time and during the week fol-
lowing the switch back to standard time than
occurred the week before each event. These statistics
show that these time changes adversely affect the
alertness of California drivers.

The conclusion in the argument above is based on
which of the following assumptions?
(A) Drivers in California as well as those in the rest
of the United States have similar driving
patterns.
(B) The observed increases in accident rates are due
almost entirely to an increase in the number
of minor accidents.

time over which to judge the phenomenon
described.
(D) There are no other factors such as school vaca-
tions or holiday celebrations that cause
accident rates to rise during these weeks.

not produce a similar increase in accident
rates.

25. Since 1945 there have been numerous international
confrontations as tense as those that precipitated the
Second World War, and yet no large-scale conflict
has resulted. To explain this, some argue that fear
of enormous destruction such as the Second World
War produced has had a dramatic deterrent effect.

Which of the following, if true, most seriously
weakens the deterrent theory mentioned above?
(A) After the First World War, the fear of great
future destruction was as intense as it was
after the Second World war.
(B) Psychologists have determined that the fear
of retaliation tends to temper aggressiveness
among human beings.

sive today as it was forty years ago.

have occurred since 1945 have involved coun-
tries that participated in the Second World
War.
