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.

答案是Ｅ．　为什么啊！

60.   (33807-!-item-!-188;#058&007599)

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.

答案是Ｃ．　

还请各位高人指点一下！　谢谢！

58: E: weakens the conclusion by arguing that adding more officers would reduce the crime rate so that the increasing in court and prison employees is not necessary.

60: C: The conclusion states explicitly that there is no such correlation, correlation between X (budget deficit) and Y (trade deficit). C states that reducing X will not NECESSARILY lowing Y. It can still happen, but not necessarily so.
