9. Complaints that milk bottlers take enormous markups on the bottled milk sold to consumers are most likely to arise when least warranted by the actual spread between the price that bottlers pay for raw milk and the price at which they sell bottled milk. The complaints occur when the bottled-milk price rises, yet these price increases most often merely reflect the rising price of the raw milk that bottlers buy from dairy farmers. When the raw-milk price is rising, the bottlers’ markups are actually smallest proportionate to the retail price. When the raw-milk price is falling, however, the markups are greatest.
If all of the statements above are true, which one of the following must also be true on the basis of them?
(A) Consumers pay more for bottled milk when raw-milk prices are falling than when these prices are rising.
(B) Increases in dairy farmers’ cost of producing milk are generally not passed on to consumers.
(C) Milk bottlers take substantially greater markups on bottled milk when its price is low for an extended period than when it is high for an extended period.
(D) Milk bottlers generally do not respond to a decrease in raw-milk prices by straightaway proportionately lowering the price of the bottled milk they sell.
(E) Consumers tend to complain more about the price they pay for bottled milk when dairy farmers are earning their smallest profits.

如何理解C是错的？这里的for an extended period 是什么意思？C是否错在原文中的price 是以 raw milk 为参照的，而c中将它改为了 bottled milk的价格？

Questions 10-11
If the public library shared by the adjacent towns of Redville and Glenwood were relocated from the library’s current, overcrowded building in central Redville to a larger, available building in central Glenwood, the library would then be within walking distance of a larger number of library users. That is because there are many more people living in central Glenwood than in central Redville, and people generally will walk to the library only if it is located close to their homes.
10 Which one of the following, if true, most strengthens the argument?
(A) The public library was located between Gienwood and Redville before being moved to its current location in central Redville.
(B) The area covered by central Glenwood is approximately the same size as that covered by central Redville.
(C) The building that is available in Glenwood is smaller than an alternative building that is available in Redville.
(D) Many of the people who use the public library do not live in either Glenwood or Redville.
(E) The distance that people currently walk to get to the library is farther than what is generally considered walking distance.

问题：答案B，面积相同，住的人更多，所以可能去图书馆的人就会更多，是这样理解嘛？

Questions 14-15
Economist: Some policymakers believe that our country’s continued economic growth requires a higher level of personal savings than we currently have. A recent legislative proposal would allow individuals to set up savings accounts in which interest earned would be exempt from taxes until money is withdrawn from the account. Backers of this proposal claim that its implementation would increase the amount of money available for banks to loan at a relatively small cost to the government in lost tax revenues. Yet, when similar tax-incentive programs were tried in the past, virtually all of the money invested through them was diverted from other personal savings, and the overall level of personal savings was unchanged.

15. The author criticizes the proposed tax-incentive program by
(A) challenging a premise on which the proposal is based
(B) pointing out a disagreement among policymakers
(C) demonstrating that the proposal’s implementation is not feasible
(D) questioning the judgment of the proposal’s backers by citing past cases in which they had advocated programs that have proved ineffective
(E) disputing the assumption that a program to encourage personal savings is needed
答案为A。这里的premise是指：“the exempting of personal saving from taxes would lead to the increase of the total amount of personal saving”嘛？
选项D为什么错？个人理解：because it is undetermined that the past cases cited by the author had been advocated by the proposal’s backers. 是这样嘛？

1. 原文可以理解为MAKEUP是不变的。。C错在MAKEUP的比较上。

2。好象JOYWZY几天前问过，讨论得很详细的。。找找看

3。需要理解论据是如何支持结论的。论据是通过举一个相似的例子，即用户可能只是会把别的ACCOUNT转到 ACCOUNT WIHE MORE BENEFIT（undermine the assumption）说明银行的存款不会增加，CHALLENGE了结论。D只是指出CITE THE PAST CASE and point out such case are ineffecitve...这个没错。。但是只是表面动作。。没有提到本质的东东。。SUCH CASE和现在的什么联系？没有指出证据是如何CHANLLEGE结论的。

1.C is not correct. The reason is that "for an extended period" does not exist in the question and it is not relevant.
