5.     Psychological research indicates that college hockey and football players are more quickly moved to hostility and aggression than are college athletes in noncontact sports such as swimming. But the researchers’ conclusion—that contact sports encourage and teach participants to be hostile and aggressive—is untenable. The football and hockey players were probably more hostile and aggressive to start with than the swimmers.

Which of the following, if true, would most strengthen the conclusion drawn by the psychological researchers?

(A) The football and hockey players became more hostile and aggressive during the season and remained so during the off-season, whereas there was no increase in aggressiveness among the swimmers.

(B) The football and hockey players, but not the swimmers, were aware at the start of the experiment that they were being tested for aggressiveness.

(C) The same psychological research indicated that the football and hockey players had a great respect for cooperation and team play, whereas the swimmers were most concerned with excelling as individual competitors.

(D) The research studies were designed to include no college athletes who participated in both contact and noncontact sports.（A）

(E) Throughout the United States, more incidents of fan violence occur at baseball games than occur at hockey or football games.

17.   Companies considering new cost-cutting manufacturing processes often compare the projected results of making the investment against the alternative of not making the investment with costs, selling prices, and share of market remaining constant.

Which of the following, assuming that each is a realistic possibility, constitutes the most serious disadvantage for companies of using the method above for evaluating the financial benefit of new manufacturing processes?

(A) The costs of materials required by the new process might not be known with certainty.

(B) In several years interest rates might go down, reducing the interest costs of borrowing money to pay for the investment.

(C) Some cost-cutting processes might require such expensive investments that there would be no net gain for many years, until the investment was paid for by savings in the manufacturing process.

(D) Competitors that do invest in a new process might reduce their selling prices and thus take market share away from companies that do not.（D）

(E) The period of year chosen for averaging out the cost of the investment might be somewhat longer or shorter, thus affecting the result.

1题，问题的关键在两种运动员都要自己和自己比，不要和别人比。A就说明了，football/hockey运动员在赛季中变暴力了。游泳的没变。是正确答案。B,C,D无关,不说了。E比较了两类运动的球迷，但不能说明变暴力了，因为正如文中怀疑的那样，可能正是因为football球迷本来就暴力，所以喜欢闹事。而不是因为看了球才闹

2题，这个题比较特别，不是问哪一个削弱了上边的方法的合理性，而是问哪一个情况下采用上面方法的公司最吃亏。所以选D.因为生意被人家抢了，这里要有个假设，就是公司用了上面的方法，所以没改革。为什么可以这样假设呢？因为每种情况都应该是公司开始没有预料到的情况，也就是公司做的决定都是错误的。依此类推，D最好。

看了LS上解释有点启发　　觉得这样理解是不是更清楚一些

1：第一题费解之处就是题目中是反驳researchers’ conclusion的，并提出了The football and hockey players were probably more hostile and aggressive to start with than the swimmers的结论，而问题是要加强the conclusion drawn by the psychological researchers　理清了之后　就容易选A了

2.问的是the most serious disadvantage for companies of using the method above for evaluating the financial benefit of new manufacturing processes，就是说采用了以上那个评估方法的公司会有什么disadvantage,应该从方法中找。评估的方法是：比较投资某个项目与不投资这个项目的 costs, selling prices, and share of market remaining constant。D中说竞争者投资这个项目后降低了价格，占了市场份额。在这种情况下，那间公司利用以上的评估方法认为不投资这个项目是正确，事实上错过了投资的机会。也就是利用那个评估方法的disadvantage.

不知我说的清楚否？？　　N人指教
