4. Vague laws set vague limits on people’s freedom,
which makes it impossible for them to know for
certain whether their actions are legal. Thus, under
vague laws people cannot feel secure.
The conclusion follows logically if which one of the
following is assumed?
(A) People can feel secure only if they know for
certain whether their actions are legal.
(B) If people do not know for certain whether their
actions are legal, then they might not feel
secure.
(C) If people know for certain whether their actions
are legal, they can feel secure.
(D) People can feel secure if they are governed by
laws that are not vague.
(E) Only people who feel secure can know for
certain whether their actions are legal.

Since the deregulation of airlines, delays at the nation's increasingly busy airports have increased by 25 percent. To combat this problem, more of the takeoff and landing slots at the busiest airports must be allocated to commercial airlines.
Which of the following, if true, casts the most doubt on the effectiveness of the solution proposed above?
(A) The major causes of delays at the nation's busiest airports are bad weather and overtaxed air traffic control equipment.
(B) Since airline deregulation began, the number of airplanes in operation has increased by 25 percent.
(C) Over 60 percent of the takeoff and landing slots at the nation's busiest airports are reserved for commercial airlines.
(D) After a small midwestern airport doubled its allocation of takeoff and landing slots, the number of delays that were reported decreased by 50 percent.
(E) Since deregulation the average length of delay at the nation's busiest airports has doubled.

The proposal to hire ten new police officers in Middletown is quite foolish. There is sufficient funding to pay the salaries of the new officers, but not the salaries of additional court and prison employees to process the increased caseload of arrests and convictions that new officers usually generate.
Which of the following, if true, will most seriously weaken the conclusion drawn above?
(A) Studies have shown that an increase in a city's police force does not necessarily reduce crime.
(B) When one major city increased its police force by 19 percent last year, there were 40 percent more arrests and 13 percent more convictions.
(C) If funding for the new police officers' salaries is approved, support for other city services will have to be reduced during the next fiscal year.
(D) In most United States cities, not all arrests result in convictions, and not all convictions result in prison terms.
(E) Middletown's ratio of police officers to citizens has reached a level at which an increase in the number of officers will have a deterrent effect on crime.

Bank depositors in the United States are all financially protected against bank failure because the government insures all individuals' bank deposits. An economist argues that this insurance is partly responsible for the high rate of bank failures, since it removes from depositors any financial incentive to find out whether the bank that holds their money is secure against failure. If depositors were more selective, then banks would need to be secure in order to compete for depositors' money.
Which of the following, if true, most seriously weakens the economist's argument?
(A) Before the government started to insure depositors against bank failure, there was a lower rate of bank failure than there is now.
(B) When the government did not insure deposits, frequent bank failures occurred as a result of depositors' fears of losing money in bank failures.
(C) Surveys show that a significant proportion of depositors are aware that their deposits are insured by the government.
(D) There is an upper limit on the amount of an individual's deposit that the government will insure, but very few individuals' deposits exceed this limit.
(E) The security of a bank against failure depends on the percentage of its assets that are loaned out and also on how much risk its loans involve.

Large national budget deficits do not cause large trade deficits. If they did, countries with the largest budget deficits would also have the largest trade deficits. In fact, when deficit figures are adjusted so that different countries are reliably comparable to each other, there is no such correlation.
If the statements above are all true, which of the following can properly be inferred on the basis of them?
(A) Countries with large national budget deficits tend to restrict foreign trade.
(B) Reliable comparisons of the deficit figures of one country with those of another are impossible.
(C) Reducing a country's national budget deficit will not necessarily result in a lowering of any trade deficit that country may have.
(D) When countries are ordered from largest to smallest in terms of population, the smallest countries generally have the smallest budget and trade deficits.
(E) Countries with the largest trade deficits never have similarly large national budget deficits. |
