求助几道逻辑
The fact that several of the largest senior citizens’ organizations are constituted almost exclusively of middle-class elderly people has led critics to question the seriousness of those organizations’ commitment to speaking out on behalf of the needs of economically disadvantaged elderly people.
Which of the following generalizations, if true, would help to substantiate the criticism implicit in the statement above?
(B) The needs of disadvantaged elderly people differ in some ways from those of other disadvantaged groups within contemporary society.
((E) People usually join organizations whose purpose is to further the economic, political, or social interests of their members.
选项E：说加入组织的人为了他们的成员（their members）的利益努力。文中的意思exclusively 的 middle-class elderly people 加入组织为disadvantaged elderly people谋求利益。E选项怎么都不象加强啊！！！
Corporate Officer: Last year was an unusually poor one for our chemical division, which has traditionally contributed about 60 percent of the corporation’s profits. It is therefore encouraging that there is the following evidence that the pharmaceutical division is growing stronger: it contributed 45 percent of the corporation’s profits, up from 20 percent the previous year.
On the basis of the facts stated, which of the following is the best critique of the evidence presented above?
(A) The increase in the pharmaceutical division’s contribution to corporation profits could have resulted largely from the introduction of single, important new product.
(C) The percentage of the corporation’s profits attributable to the pharmaceutical division could have increased even if that division’s performance had not improved.
这里问题要求削弱文中的critique，C选项说即使药部门工作成绩不提高，它为公司创造的profits也提高了。这就是文中的意思：It is therefore encouraging that there is the following evidence that the pharmaceutical division is growing stronger。注意这里的it is therfore就是说因为化学部的poor导致了pharmaceutical division is growing stronger。
C再这里不是加强了吗？？
When people predict that certain result will not take place unless a certain action is taken, they believe that they have learned that the prediction is correct when the action is taken and the result occurs. On reflection, however, it often becomes clear that the result admits of more than one interpretation.
Which of the following, if true, best supports the claims above?
(A) Judging the success of an action requires specifying the goal of the action.
(B) Judging which action to take after a prediction is made requires knowing about other actions that have been successful in similar past situations.
(C) Learning whether a certain predictive strategy is good requires knowing the result using that strategy through several trials.
(D) Distinguishing a correct prediction and effective action from an incorrect prediction and ineffective action is often impossible.
(E) Making a successful prediction requires knowing the facts about the context of that prediction.
这道题目有点找不到北，希望高手指点一下。谢谢
A government agency that reimburses its clients for bills they have paid for medical care has had this year’s budget cut. To save money without cutting reimbursements or otherwise harming clients financially, it plans to delay reimbursements to clients for forty days, thereby earning $180 million per year in interest on the reimbursement money.
Which of the following, if true, is the best criticism of the agency’s plan?
(C) Some clients borrow money to pay their medical bills; they will pay forty extra days of interest on these loans.
(D) Some clients pay their medical bills immediately, but they often take more than forty days to file with the agency for reimbursement.
这道题目也不是很明白，答案给了C，C说顾客借钱看病，他们要付利息。文中这里：thereby earning $180 million per year in interest on the reimbursement money.我的理解是说government赚了180 million.顾客借钱付医药费的利息不需要government来承担吧。
In a political system with only two major parties, the entrance of a third-party candidate into an election race damages the chances of only one of the two major candidates. The third-party candidate always attracts some of the voters who might otherwise have voted for one of the two major candidates, but not voters who support the other candidate. Since a third-party candidacy affects the two major candidates unequally, for reasons neither of them has any control over, the practice is unfair and should not be allowed.
If the factual information in the passage above is true, which of the following can be most reliably inferred from it?
(A) If the political platform of the third party is a compromise position between that of the two major parties, the third party will draw its voters equally from the two major parties.
(B) If, before the emergence of a third party, voters were divided equally between the two major parties, neither of the major parties is likely to capture much more than one-half of the vote.
(C) A third-party candidate will not capture the votes of new voters who have never voted for candidates of either of the two major parties.
(D) The political stance of a third party will be more radical than that of either of the two major parties.
(E) The founders of a third party are likely to be a coalition consisting of former leaders of the two major parties.
