8. Of 2,500 people who survived a first heart attack, those who did not smoke had their first heart attack at a median age of 62. However, of those 2,500 people who smoked two packs of cigarettes a day had their first heart attack at a median age of 51. On the basis of this information, it can be concluded that nonsmokers tend to have a first heart attack eleven years later than do people who smoke two packs of cigarettes a day.

The conclusion is incorrectly drawn from the information given because this information does not include

(A) the relative seventy of heart attacks suffered by smokers and nonsmokers

(B) the nature of the different medical treatments that smokers and nonsmokers received after they had survived their first heart attack

(C) how many of the 2,500 people studied suffered a second heart attack

(D) the earliest age at which a person who smoked two packs a day had his or her first heart attack

(E) data on people who did not survive a first heart attack

答案：E，E我觉得是无关选项。

18. People cannot be morally responsible for things over which they have no control. Therefore, they should not be held morally responsible for any inevitable consequences of such things, either. Determining whether adults have any control over the treatment they are receiving can be difficult. Hence in some cases it can be difficult to know whether adults bear any moral responsibility for the way they are treated. Everyone, however, sometimes acts in ways that are an inevitable consequently of treatment received as an infant and infants clearly cannot control, and so are not morally responsible for the treatment they receive.

Anyone making the claims above would be logically committed to which one of the following further claims.

(A) An infant should never be held morally responsible for an action that infant has performed.

(B) There are certain commonly performed actions for which no one performing those actions should ever be held morally responsible.

(C) Adults who claim that they have no control over the treatment they are receiving should often be held at least partially responsible for being so treated.

(D) If a given action is within a certain person’s control that person should be held morally.

(E) No adult should be held morally responsible for ever action he or she performs.

答案：E，我选A，题干没完全读懂。

19. Fares on the city-run public buses in Greenville are subsidized by city tax revenues, but among the beneficiaries of the low fares are many people who commute from outside the city to jobs in Greenville. Some city councilors argue that city taxes should be used primarily to benefit the people who pay them, and therefore that bus fares should be raised enough to cover the cost of the service.

Each of the following, if true, would weaken the argument advanced by the city councilors EXCEPT:

(A) Many businesses whose presence in the city is beneficial to the city’s taxpayers would relocate outside the city if public-transit fare were more expensive.

(B) By providing commuters with economic incentives to drive to work, higher transit fares would worsen air pollution in Greenville and increase the cost of maintaining the city’s streets.

(C) Increasing transit fares would disadvantage those residents of the city whose low incomes make them exempt from city taxes, and all city councilors agree that these residents should be able to take advantage of city-run services.

(D) Voters in the city, many of whom benefit from the low transit fares are strongly opposed to increasing local taxes.

(E) People who work in Greenville and earn wages above the nationally mandated minimum all pay the city wage tax of 5 percent.

答案：D，我想问E为什么是削弱？

谢谢。

8.注意第一句话：who survived a first heart。原文however后面，没有survive。所以，实际上原文给出的是两个无关（无意义，用死人数比患病数）比较！答案E，使得两个比较有了意义。我们很少怀疑原文，所以进了套儿。
这种题，简直无耻之尤。我碰到好几个了。

天啊，我根本没有发现。谢谢SIEBEL。

这种题太无耻了。

那么，18,19题呢？

18）people have no control over things -> People cannot be morally responsible for these things .中间有些废话。作者接着说：每个人，有时候 act in ways like infac，由于infants can not control 。因此可以得到：People cannot be morally responsible for these things。我觉得这种题不是一个非常严密的逻辑推理。但可以通过读懂作者要告诉我们什么而得到答案。
19）E只是说这帮人其实只付出了占city wag tax 的5%。很少的一部分而已。如果.....
答案D很容易得到。

谢谢perfection和SIEBEL，我明白了。

我想请问当碰到一堆话时，是不是要提取中心思想，也就是论证的论点，就行了，如T18。

谢谢。

对头三。
一个长段的逻辑推理一般要注意以下几个（从书来的）
1中心概念和相关概念，包含限定词。
2 条件，包含条件和结论的推理关系。
3 结论。注意其中的限定性语句。

虽然however后面没有survived这个词,但指的都是同一组人of those 2,500 people .该题的关键是结论中的smokers和nonsmokers与论据中的范围不一样了,作为结论的范围大了.试想想, 如果smokers中只有年轻的活过来了,而nonsmokers中年老的却活过来了, 结论还成立么? E讲的就是要考虑没活过来的人的资料.
