Mayor Four years ago when we reorganized the city police department in order to save money, critics claimed that the reorganization would make the police less responsive to citizens and would thus lead to more crime. The police have compiled theft statistics from the years following the reorganization that show that the critics were wrong. There was an overall decrease in reports of thefts of all kinds, including
small thefts.

Which of the following, if true, most seriously challenges the mayor's argument?
(A) When city police are perceived as unresponsive, victims of theft are less likely to report thefts to the police.
(B) The mayor's critics generally agree that police statistics concerning crime reports provide the most reliable available data on crime rates.
(C) In other cities where police departments have been similarly reorganized, the numbers of reported thefts have generally risen following reorganization.
(D) The mayor's reorganization of the police department failed to save as much money as it was intended to save.
(E) During the four years immediately preceding the reorganization, reports of all types of theft had been rising steadily in comparison to reports of other crimes.

It takes a particular talent to be a successful business manager. Business courses can help people to solve management problems, but such courses can do so only for those people with managerial talent. Such
people should take business courses to acquire ideas that they can subsequently use to good advantage if management problems happen to arise.

(A) People who are helped by business courses in solving management problems also have managerial talent.
(B) People who are already skilled at solving management problems are unlikely to benefit from business courses.
(C) Most ideas that are used successfully in solving management problems are those acquired in business courses.
(D) People who lack managerial talent are more likely to take business courses than are people who have managerial talent.
(E) Those people who have never taken business courses are unable to solve management problems when such problems arise

When a driver is suspected of having had too much to drink, testing the driver's ability to walk a straight line gives a more reliable indication of fitness to drive than does testing the driver's blood-alcohol level.

Which of the following, if true, best supports the claim made in the statement above?
(A) Not all observers will agree whether or not an individual has succeeded in walking a straight line.
(B) Because of genetic differences and variations in acquired tolerance to alcohol, some individuals suffer more serious motor impairment from a given high blood-alcohol level than do others.
(C) Tests designed to measure blood-alcohol levels are accurate, inexpensive, and easy to administer.
(D) More than half the drivers involved in fatal accidents have blood-alcohol levels that exceed the legal limit, whereas in less-serious accidents the proportion of legally intoxicated drivers is lower.
(E) Some individuals with high blood-alcohol levels are capable of walking a straight line but are not capable of driving safely.
