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.

这题说支持psychological researchers的结论,也就是支持contact sports encourage and teach participants to be hostile and aggressive,而反对者认为他们更易发动暴力.A中became more 和remained so是不是矛盾啊?而且觉得A是支持反对者的.不明白为什么选A.

11. Some observers have concluded that the rise in the price of pepper means that the switch by some growers from pepper to cocoa left those growers no better off than if none of them had switched; this conclusion, however, is unwarranted because it can be inferred to be likely that

第五题美眉问了个很好的问题，不过如果将researcher的结论理解为破折号内的那一句，就一个答案也没有了，如果将其理解为全段的段意，那么答案该是A。实际上，我也经常对提问的这一句头疼不已，有时是看少了，有时又看多了，很有点郁闷呢

11。switch by some growers from pepper to cocoa left those growers no better off than if none of them had switched。 no better off看似复杂，其实意思就是不会更好，全句：一些grower不种pepper改种cocoa（的景况）其实并不比他们没（从pepper领域离开）改种cocoa前好。

15。Technological education is worsening. People between eighteen and twenty-four, who are just emerging from their formal education, are more likely to be technologically illiterate than somewhat older adults. And yet, issues for public referenda will increasingly involve aspects of technology。技术教育正变得越来越遭。刚刚接受完正规教育、18至24岁的人们比年纪比他们大的人更有可能是技术盲。然而，一些需要全民考虑的问题正越来越多地涉及到技术层面

仓促之间，MM就权当参考吧

Dear man, acturally, you have answered the question to yourself. The part you highlighted is the key for the answer. If the hocky players are normal people, then they will act as same as the other peoples do. But since they remine their aggressive activities, they are rude inately.

11. Some observers have concluded that the rise in the price of pepper means that the switch by some growers from pepper to cocoa left those growers no better off than if none of them had switched; this conclusion, however, is unwarranted because it can be inferred to be likely that

个人以为，这段话有两个观点：

一、Psychological researcher的：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. the researchers’ conclusion—that contact sports encourage and teach participants to be hostile and aggressive.

二、the author of this argument 驳斥上述观点的: 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

题目是问支持Psychological researcher 的观点，所以支持 the conclusion—that contact sports encourage and teach participants to be hostile and aggressive.的就是答案。
