1. Armtech, a temporary-employment agency, previously
gave its employees 2.5 paid vacation days after each
700 hours worked. Armtech’s new policy is to give
its employees 5.0 paid vacation days after each 1,200
hours worked. Therefore, this new policy is more
generous to Armtech employees in giving them more
vacation days per hour worked than the old policy did.
Which of the following is an assumption on which
the argument depends?
(A) Most current Armtech employees approve of the
company’s new vacation policy.
(B) A few Armtech employees leave the company
before having worked 700 hours.
(C) Most Armtech employees were not aware that
the company planned to change its vacation
policy until after it had already done so.
(D) A significant portion of Armtech employees stay
with the company long enough to work for
1,200 hours.
(E) Armtech’s new vacation policy closely matches
the vacation policies of competing temporary
employment agencies.
2 The global population of frogs has declined in recent
years while the amount of ultraviolet radiation reaching
the Earth has increased. Since the genetic material in
frog eggs is harmed when exposed to ultraviolet radi-
ation, and since the eggs themselves are not protected
by shells or leathery coverings but are gelatinous, the
frog population decline is probably due, at least in
part, to the ultraviolet radiation increase.
Which of the following, if true, provides the strongest
support for the argument?
(A) Even in those regions where there has been no
significant increase in ultraviolet radiation, only
a small proportion of the frog eggs that are laid
ever hatch.
(B) In areas where there has been the least decline
in frog populations, populations of species of
insects that frogs eat have decreased.
(C) The eggs of frog species whose populations are
declining tend to have higher concentrations of
damaging pesticides than do the eggs of frog
species whose populations have not declined.
(D) In many places where turtles, which lay eggs
with tough, leathery coverings, share habitats
with frogs, turtle populations are also in decline.
(E) Populations of frog species that hide their eggs
beneath rocks or under sand have declined
considerably less than have populations of frog
species that do not cover their eggs.
Questions 3-8
A doctor is scheduling one appointment each with five

(D) L, J, K, N, M
(E) L, J, N, M, K
4.If J is scheduled for appointment 2, which of the
following can be true?
(A) K is scheduled for appointment 3.

6.Which of the following is a complete and accurate
list of patients any one of whom can be the patient
scheduled for appointment 2?
(A) K
(B) J, K
(C) J, M
(D) J, K, L
(E) K, L, M
7.If M is scheduled for appointment 5, which of the
following can be true of the scheduling?

(B) N’s appointment is appointment 1.
(C) J’s appointment is earlier than K’s appointment.
