The more frequently employees take time to exercise during working hours each week, the fewer sick days they take. Even employees who exercise only once a week during working hours take less sick time than those who do not exercise. Therefore, if companies started fitness programs, the absentee rate in those companies would decrease significantly.

Which of the following, if true, most seriously weakens the argument above?

• Employees who exercise during working hours occasionally fall asleep for short periods of time after they exercise.
• Employees who are frequently absent are the least likely to cooperate with or to join a corporate fitness program.
• Employees who exercise only once a week in their company's fitness program usually also exercise after work.
• Employees who exercise in their company's fitness program use their working time no more productively than those who do not exercise.
• Employees who exercise during working hours take slightly longer lunch breaks than employees who do not exercise.

Recently a court ruled that current law allows companies to reject a job applicant if working in the job would entail a 90 percent chance that the applicant would suffer a heart attack. The presiding judge justified the ruling, saying that it protected both employees and employers.

The use of this court ruling as part of the law could not be effective in regulating employment practices if which of the following were true?

• The best interests of employers often conflict with the interests of employees.
• No legally accepted methods exist for calculating the risk of a job applicant's having a heart attack as a result of being employed in any particular occupation.
• Some jobs might involve health risks other than the risk of heart attack.
• Employees who have a 90 percent chance of suffering a heart attack may be unaware that their risk is so great.
• The number of people applying for jobs at a company might decline if the company, by screening applicants for risk of heart attack, seemed to suggest that the job entailed high risk of heart attack.

Guitar strings often go "dead"—become less responsive and bright in tone—after a few weeks of intense use. A researcher whose son is a classical guitarist hypothesized that dirt and oil, rather than changes in the material properties of the string, were responsible.

Which of the following investigations is most likely to yield significant information that would help evaluate the researcher's hypothesis?

• Determining whether a metal alloy is used to make the strings used by classical guitarists
• Determining whether classical guitarists make their strings go dead faster than do folk guitarists
• Determining whether identical lengths of string, of the same gauge, go dead at different rates when strung on various brands of guitars
• Determining whether a dead string and a new string produce different qualities of sound
• Determining whether smearing various substances on new guitar strings causes them to go dead

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.

Which of the following can be most properly inferred from the passage about the products whose importation was banned?

• Those products had been cheaper to import than they were to make within country Z's fledgling industries.
• Those products were the ones that country Z was hoping to export in its turn, once the fledgling industries matured.
• Those products used to be imported from just those countries to which country Z's exports went.
• Those products had become more and more expensive to import, which resulted in a foreign trade deficit just before the ban.
• Those products used to be imported in very small quantities, but they were essential to country Z's economy.

Treatment for hypertension forestalls certain medical expenses by preventing strokes and heart disease.Yet any money so saved amounts to only one-fourth of the expenditures required to treat the hypertensive population.Therefore, there is no economic justification for preventive treatment for hypertension.

Which of the following, if true, is most damaging to the conclusion above?

• The many fatal strokes and heart attacks resulting from untreated hypertension cause insignificant medical expenditures but large economic losses of other sorts.
• The cost, per patient, of preventive treatment for hypertension would remain constant even if such treatment were instituted on a large scale.
• In matters of health care.Economic considerations should ideally not be dominant.
• Effective prevention presupposes early diagnosis, and programs to ensure early diagnosis are costly.
• The net savings in medical resources achieved by some preventive health measures are smaller than the net losses attributable to certain other measures of this kind.

The sustained massive use of pesticides in farming has two effects that are especially pernicious.First, it often kills off the pests' natural enemies in the area.Second, it often unintentionally gives rise to insecticide-resistant pests, since those insects that survive a particular insecticide will be the ones most resistant to it, and they are the ones left to breed.

From the passage above, it can be properly inferred that the effectiveness of the sustained massive use of pesticides can be extended by doing which of the following, assuming that each is a realistic possibility?

• Using only chemically stable insecticides
• Periodically switching the type of insecticide used
• Gradually increasing the quantities of pesticides used
• Leaving a few fields fallow every year
• Breeding higher-yielding varieties of crop plants
