91. When a polygraph test is judged inconclusive, this is no reflection on the examinee. Rather, such a judgment
means that the test has failed to show whether the examinee was truthful or untruthful. Nevertheless, employers
will sometimes refuse to hire a job applicant because of an inconclusive polygraph test result.
Which of the following conclusions can most properly be drawn from the information above?

（A)Most examinees with inconclusive polygraph test results are in fact untruthful.
(B)Polygraph tests should not be used by employers in the consideration of job applicants.
(C)An inconclusive polygraph test result is sometimes unfairly held against the examinee.
(D)A polygraph test indicating that an examinee is untruthful can sometimes be mistaken.
(E)Some employers have refused to consider the results of polygraph tests when evaluating job applicants.



92. According to the new office smoking regulations, only employees who have enclosed office may smoke at
their desks. Virtually all employees with enclosed offices are at the professional level, and virtually all secretarial
employees lack enclosed offices. Therefore, secretaries who smoke should be offered enclosed offices.
Which of the following is an assumption that enables the conclusion above to be properly drawn?
(A) Employees at the professional level who do not smoke should keep their enclosed offices.
(B) Employees with enclosed offices should not smoke at their desks, even though the new regulations permit
them to do so.
(C) Employees at the secretarial level should be allowed to smoke at their desks, even if they do not have
enclosed offices.
(D) The smoking regulations should allow all employees who smoke an equal opportunity to do so, regardless
of an employee’s job level.
(E) The smoking regulations should provide equal protection from any hazards associated with smoking to all
employees who do not smoke.



93. Dental researchers recently discovered that tooth-brushes can become contaminated wth bacterial that
cause pneumonia and strep throat. They found that contamination usually occurs after toothbrushes have been
used for four weeks. For that reason, people should replace their toothbrushes at least once a month.
Which of the following, if true, would most weaken the conclusion above?
(A) The dental researchers could not discover why toothbrush contamination usually occurred only after
toothbrushes had been used for four weeks.
(B) The dental researchers failed to investigate contamination of toothbrushes by viruses, yeasts, and other
pathogenic microorganisms.
(C) The dental researchers found that among people who used toothbrushes contaminated with bacterial that
cause pneumonia and strep throat, the incidence of these diseases was no higher than among people who
used uncontaminated toothbrushes.
(D) The dental researchers found that people who rinsed their toothbrushes thoroughly in hot water after each
use were as likely to have contaminated toothbrushes as were people who only rinsed their toothbrushes
hurriedly in cold water after each use.
(E) The dental researchers found that, after six weeks of use, greater length of use of a toothbrush did not
correlate with a higher number of bacterial being present.



Questions 94-95 are based on the following.
To protect certain fledgling industries, the government of country Z banned imports of the types of products
those industries were starting to make. As a direct result, the cost of those products to the buyers, several
export-dependent industries in Z, went up, sharply limiting the ability of those industries to compete effectively in
their export markets.
94. Which of the following can be most properly inferred from the passage about the products whose importation
was banned?
(A) Those products had been cheaper to import than they were to make within country Z’s fledgling industries.
(B) Those products were ones that country Z was hoping to export in its turn, once the fledgling industries
matured.
(C) Those products used to be imported from just those countries to which country Z’s exports went.
(D) Those products had become more and more expensive to import, which resulted in a foreign trade deficit
just before the ban.
(E) Those products used to be imported in very small quantities, but they were essential to country Z’s
economy.

95. Which of the following conclusions about country Z’s adversely affected export-dependent industries is best
supported by the passage?
(A) Profit margins in those industries were not high enough to absorb the rise in costs mentioned above.
(B) Those industries had to contend with the fact that other countries banned imports from country Z.
(C) Those industries succeeded in expanding the domestic market for their products.
(D) Steps to offset rising materials costs by decreasing labor costs were taken in those industries.
(E) Those industries started to move into export markets that they had previously judged unprofitable.

answer:
91.
The passage indicates that an inconclusive polygraph test tells nothing about the person who has taken the test,
and yet employers sometimes refuse to hire someone whose results from such a test are inclusive. Treating lack
of information as if it were unfavorable evidence about a person can reasonably be considered unfair. There, C
is the best choice.
Choice A is not supported, since the passage says that an inconclusive polygraph test is no reflection on the
examinee. Neither B nor D is supported, since the information given includes nothing either implicit or explicit
about polygraph tests that yield conclusive results. Since the passage is consistent with both E and its denial, E
is not supported.

92.
The regulations allow some employees-those with enclosed offices-but not others the opportunity to smoke at
their desks. If it is assumed that the regulations should allow all employees equal opportunity to smoke, those
who are currently denied this opportunity should be given it, and so secretaries who smoke should be offered
enclosed offices. Therefore, choice D is the best answer.
None of the other choices enables the conclusion to be properly drawn. Choice A tends to conflict with the
conclusion, unless some enclosed offices are vacant. Choice B supports no conclusion about how secretaries
should be treated, and choice C undermines the conclusion. Finally, nonsmokers already have equal protection
from hazards, so choice E cannot be used to justify making any changes.

93.
According to choice C, using a contaminated toothbrush does not increase the incidence of infection, so the
recommendation to replace a toothbrush before it becomes contaminated is greatly undermined. Choice C is
therefore the best answer.
Since the recommendation is based on the discovery that bacterial contamination occurs after about four weeks,
the researchers’ inability to discover why contamination takes that long to appear does not weaken the
recommendation (choice A), nor does their failure to investigate other forms of contamination (choice B), nor
does the discovery that contamination does not worsen after six weeks (choice E). According to choice D, even
thorough washing cannot prevent contamination, so replacing the toothbrush appears more essential, rather
than less so.

94.
In Z, when the government banned imports of certain products the cost of those produces rose, so the products must have been cheaper to import than they were to make in Z. Therefore choice A is the best answer.
None of the other choices can be inferred. Country Z need have had no plan to export those products later
(choice B), nor need the products have come previously from those countries to which country Z exported goods (choice C). The products need not have become more expensive before the ban (choice D), and they could have been imported in relatively large quantities (choice E).

95.
When the cost of the products rose, the competitive ability of those export-dependent industries that bought
them was sharply limited. This fact strongly supports the claim that those industries did not have sufficiently high
profit margins to enable them to absorb the price increase, so choice A is the best answer.
Given the limitation on their competitive ability, it is unlikely that those industries would be able either to expand
their domestic markets (choice C) or to enter into new export markets (choice E). The other choices relate
situations that would be possible but that are not strongly supported: other countries could have continued to
permit imports from Z (choice B), and the industries may have unable to decrease labor costs (choice D).
