2. High school students who feel that they are not
succeeding in high school often drop out before
graduating and go to work. Last year, however, the
city’s high school dropout rate was significantly
lower than the previous year’s rate. This is
encouraging evidence that the program instituted
two years ago to improve the morale of high school
students has begun to take effect to reduce dropouts.
Which one of the following, if true about the last
year, most seriously weakens the argument?
----------Cause and Effect Problems NO.2

(A) There was a recession that caused a high level
of unemployment in the city.
(B) The morale of students who dropped out of
high school had been low even before they
reached high school.
(C) As in the preceding year, more high school
students remained in school than dropped
out.
(D) High schools in the city established placement
offices to assist their graduates in obtaining
employment.
(E) The antidropout program was primarily aimed
at improving students’ morale in those high
school with the highest dropout rates.

An overly centralized economy, not the changes in the climate, is responsible for the poor agricultural production in Country X since its new government came to power.  Neighboring Country Y has experienced the same climatic conditions, but while agricultural production has been falling in Country X, it has been rising in Country Y.
Which of the following, if true, would most weaken the argument above?
(A) Industrial production also is declining in Country X.
(B) Whereas Country Y is landlocked, Country X has a major seaport.
(C) Both Country X and Country Y have been experiencing drought conditions.

Generally scientists enter their field with the goal of doing important new research and accept as their colleagues those with similar motivation.  Therefore, when any scientist wins renown as an expounder of science to general audiences, most other scientists conclude that this popularizer should no longer be regarded as a true colleague.
The explanation offered above for the low esteem in which scientific popularizers are held by research scientists assumes that
(A) serious scientific research is not a solitary activity, but relies on active cooperation among a group of colleagues
(B) research scientists tend not to regard as colleagues those scientists whose renown they envy
(C) a scientist can become a famous popularizer without having completed any important research
(D) research scientists believe that those who are well known as popularizers of science are not motivated to do important new research
(E) no important new research can be accessible to or accurately assessed by those who are not themselves scientists
51.
A company's two divisions performed with remarkable consistency over the past three years:  in each of those years, the pharmaceuticals division has accounted for roughly 20 percent of dollar sales and 40 percent of profits, and the chemicals division for the balance.

(A) Total dollar sales for each of the company's divisions have remained roughly constant.
(B) The pharmaceuticals division has faced stiffer competition in its markets than has the chemicals division.
(C) The chemicals division has realized lower profits per dollar of sales than has the pharmaceuticals division.
(D) The product mix offered by each of the company's divisions has remained unchanged.
(E) Highly profitable products accounted for a higher percentage of the chemicals division's sales than of those of the pharmaceuticals division.

The technological conservatism of bicycle manufacturers is a reflection of the kinds of demand they are trying to meet.  The only cyclists seriously interested in innovation and willing to pay for it are bicycle racers.  Therefore, innovation in bicycle technology is limited by what authorities will accept as standard for purposes of competition in bicycle races.
Which of the following is an assumption made in drawing the conclusion above?
(A) The market for cheap, traditional bicycles cannot expand unless the market for high-performance competition bicycles expands.
(B) High-performance bicycles are likely to be improved more as a result of technological innovations developed in small workshops than as a result of technological innovations developed in major manufacturing concerns.
(C) Bicycle racers do not generate a strong demand for innovations that fall outside what is officially recognized as standard for purposes of competition.
(D) The technological conservatism of bicycle manufacturers results primarily from their desire to manufacture a product that can be sold without being altered to suit different national markets.
(E) The authorities who set standards for high-performance bicycle racing do not keep informed about innovative bicycle design.

1.        24s
P：感觉自己没有在学校不会成功的高中生，往往在毕业前辍学去上班。
P：但是，去年，该市的高中辍学率明显低于上一年。
C: 表明两年前制定的提高高中生士气的计划已开始生效以减少辍学率。
推测：原题的因果关系为学校提高学生的士气导致辍学率下降。证明因果关系反了或者还有其他原因导致了这个结果。
选项分析：A
A: 失业率高说明学生不好找工作所以他们不会辍学
B：学生辍学前后的士气和他们是否会辍学没关系
C: 在校学生比辍学的多和原题没关系
D: 帮助已经毕业的学生找工作和辍学学生无关
E: 原题说的是城市的overall辍学率，不是某个学校的辍学率
2.        35s
P: 邻国Y经历了相同的气候条件，但是X国的农业生产一直在下降，而Y国却在增长。
C: 自从X国新政府上台以来，过度集中的经济而非气候的变化是X国农业生产不佳的原因。
推测：确实是天气影响了农作物产量；或者不是经济而是其他原因导致；比如两个城市种的东西不一样
选项分析：D

3.        43s
P: 通常，科学家进入其领域的目的是进行重要的新研究，并接受具有类似动机的科学家作为他们的同事。
P: 因此，当任何一位科学家通过向大众普及科学而获得声誉时，大多数其他科学家得出的结论是，不应将此普及者视为真正的同事。
推测：这些普及科学的人并不是跟那些科学家一起做调研的人；那些普及科学的人对research没有motivation
选项分析：D

B:在校感觉不成功的高中生经常退学。
P:两年前提高学生士气的一个项目起了作用导致
C:去年退学率降低。
(A) There was a recession that caused a high level of unemployment in the city.
The answer attacks the conclusion by introducing an alternate cause: it was not the morale program that led to a decrease in high dropouts, but rather the fact that no jobs were available for individuals contemplating dropping out of high school. The job availability factor is important because the first sentence of the stimulus indicates that high school students who drop out go to work. Thus, if a recession led to a high level of unemployment, this could cause high school students to rethink dropping out and stay in school.
(D) High schools in the city established placement offices to assist their graduates in obtaining employment.
帮助毕业生找到工作，但是没有毕业的高一高二的得不到学校的帮助还是会选择退学的（我开始想的就是既然学校帮助学生们找工作，那么大家肯定都会待到毕业等到学校的帮助这样就不会退学了 但是这个选项针对的仅仅是graduates，没有管其他年级的学生）

(B) research scientists tend not to regard as colleagues those scientists whose renown they envy
(C) a scientist can become a famous popularizer without having completed any important research
(D) research scientists believe that those who are well known as popularizers of science are not motivated to do important new research
(E) no important new research can be accessible to or accurately assessed by those who are not themselves scientists
