When people engage in activities that help others, their brain releases endorphins, the brain’s natural opiates, which induce in people a feeling of well-being. It has been suggested that regular release of endorphins increases people’s longevity, and a statistic on adults who regularly engage in volunteer work helping others shows that they live longer, on average, than adults who do not volunteer. However, that statistic would be what we would expect even if volunteering does not boost longevity, because __________.
(A) in the communities studied, women were much more likely to do regular volunteer work than men were, and women tend to live longer than men do
(B) the number of young adults who do regular volunteer work is on the increase
(C) the feelings of well-being induced by endorphins can, at least for a time, mask the symptoms of various conditions and diseases, provided the symptoms are mild
(D) it is rare for a person to keep up a regular schedule of volunteer work throughout his or her life
(E) some people find that keeping a commitment to do regular volunteer work becomes a source of stress in their lives

用排除法看看知道是A，但是不懂如何理解？

69. In countries where automobile insurance includes compensation for whiplash injuries sustained in automobile accidents, reports of having suffered such injuries are twice as frequent as they are in countries where whiplash is not covered. Some commentators have argued, correctly, that since there is presently no objective test for whiplash, spurious reports of whiplash injuries cannot be readily identified. These commentators are, however, wrong to draw the further conclusion that in the countries with the higher rates of reported whiplash injuries, half of the reported cases are spurious: clearly, in countries where automobile insurance does not include compensation for whiplash, people often have little incentive to report whiplash injuries that they actually have suffered.
In the argument given, the two boldfaced portions play which of the following roles?
(A) The first is evidence that has been used to support a conclusion that the argument criticizes; the second is that conclusion.
(B) The first is evidence that has been used to support a conclusion that the argument criticizes; the second is the position that the argument defends.
(C) The first is a claim that has been used to support a conclusion that the argument accepts; the second is the position that the argument defends.
(D) The first is an intermediate conclusion that has been used to support a conclusion that the argument defends; the second is the position that the argument opposes.
(E) The first presents a claim that is disputed in the argument; the second is a conclusion that has been drawn on the basis of that claim.

好了我第一次错这种类型题。。。第一个黑体部分我看到了argue就想着这应该是一个小观点（而且作者应该是认可这个观点的），然后有人认为这个观点还可以得出进一步结论，然后作者认为这个进一步结论是错的。
结果答案是A。。。
然后哪位来给我区别一下，defend,criticize,oppose这些表意上的区别？

volunteering does not boost longevity, because __________
让你找一个“因”支持volunteering does not boost longevity，找选项里有longevity和一个另外的什么“因”。

(A) in the communities studied, women were much more likely to do regular volunteer work than men were, and women tend to live longer than men do 有longevity，留下
(B) the number of young adults who do regular volunteer work is on the increase 无longevity，滚犊子
(C) the feelings of well-being induced by endorphins can, at least for a time, mask the symptoms of various conditions and diseases, provided the symptoms are mild 无longevity，滚犊子
(D) it is rare for a person to keep up a regular schedule of volunteer work throughout his or her life 无longevity，滚犊子
(E) some people find that keeping a commitment to do regular volunteer work becomes a source of stress in their lives 无longevity，滚犊子
即使没找到A的“因”这题都一样做出来了。
GMAT CR不要求你英文好，不要求你逻辑好，只要求你有基本的做人的常识即可（知道饿了吃饭，渴了喝水）。参考外国人的智商，你觉得真复杂了他们能明白？

无需知道，不影响做题。
BF的Decision Point不在这种小词。
BF题做法：
1. 找到转折词
2. 判断BF部分是论点还是论据
3. 判断两个BF部分之间的逻辑关系是同向还是反向

In one state, all cities and most towns have antismoking ordinances, a petition entitled “Petition for Statewide Smoking Restriction” is being circulated to voters by campaign workers who ask only, “Do you want to sign a petition for statewide smoking restriction?” The petition advocates a state law banning smoking in most retail establishments and in government offices that are open to the public.
Which of the following circumstances would make the petition as circulated misleading to voters who understand the proposal as extending the local ordinances statewide?

A. Health costs associated with smoking cause health insurance premiums to rise for everyone and so affect nonsmokers.
B. In rural areas of the state, there are relatively few retail establishments and government offices that are open to the public.
C. The state law would supersede the local antismoking ordinances, which contain stronger bans than the state law does.
D. There is considerable sentiment among voters in most areas of the state for restriction of smoking.
E. The state law would not affect existing local ordinances banning smoking in places where the fire authorities have determined that smoking would constitute a fire hazard.

我错了少贴一道。。。
这题目没看懂。。
