谢谢帮忙!
169. Corporate officers and directors commonly buy and sell, for their own portfolios, stock in their own corporations. Generally, when the ratio of such inside sales to inside purchases falls below 2 to 1 for a given stock, a rise in stock prices is imminent. In recent days, while the price of MEGA Corporation stock has been falling, the corporation's officers and directors have bought up to nine times as much of it as they have sold.

The facts above best support which of the following predictions?

(A) The imbalance between inside purchases and inside sales of MEGA stock will grow
even further.
(B) Inside purchases of MEGA stock are about to cease abruptly.
(C) The price of MEGA stock will soon begin to go up.
(D) The price of MEGA stock will continue to drop, but less rapidly.
(E) The majority of MEGA stock will soon be owned by MEGA's own officers and directors.

170. 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.

169.因为卖:买<2:1-->价格增长
现在是卖:买=1:9<2:1-->价格增长.
选c
170.
原文结论: 不应该增加新警察.
evidence: 虽然有钱支付警察工资, 但没钱给法院和狱警.
问weaken, 选e,
说明增加了警察, 有威慑作用, 不会带来更多的案件.也就不用支付法院和监狱了.
weaken结论, 得出应该增加新警察.

我补充解释一下：

170. 翻译：在MT雇佣10个新警察的建议是愚蠢的。有资金可以支付新警察的工资，但没有资金来支付由新警察处理新案子而增加的法院和监狱人员的费用。

原因：新警察会处理新的案子而增加新的额外费用，但没钱支付因此而增加的这笔费用
结论：不能增加新警察（即：增加新警察是愚蠢的）

weaken：E. 实际上对于新警察增加到一定数量后，如果在增加会有不同的效果（于题干不同的效果）。
