Q15.     p1-cr            57.            (34655-!-item-!-188;#058&007580)

 

Roland:  The alarming fact is that 90 percent of the people in this country now report that they know someone who is unemployed.

 

Sharon:  But a normal, moderate level of unemployment is 5 percent, with 1 out of 20 workers unemployed.  So at any given time if a person knows approximately 50 workers, 1 or more will very likely be unemployed.

 

Sharon's argument is structured to lead to which of the following as a conclusion?

 

(A) The fact that 90% of the people know someone who is unemployed is not an indication that unemployment is abnormally high.

(B) The current level of unemployment is not moderate.

(C) If at least 5% of workers are unemployed, the result of questioning a representative group of people cannot be the percentage Roland cites.

(D) It is unlikely that the people whose statements Roland cites are giving accurate reports.

(E) If an unemployment figure is given as a certain percent, the actual percentage of those without jobs is even higher.

 答案：A，我选了D。看了答案后觉得A对，但当时对not an indication that的给虎住了。D说的不太到位，擦边。

Q20.     p1-cr            58.            (34705-!-item-!-188;#058&007581)

 

Roland:  The alarming fact is that 90 percent of the people in this country now report that they know someone who is unemployed.

 

Sharon:  But a normal, moderate level of unemployment is 5 percent, with 1 out of 20 workers unemployed.  So at any given time if a person knows approximately 50 workers, 1 or more will very likely be unemployed.

 

Sharon's argument relies on the assumption that

 

(A) normal levels of unemployment are rarely exceeded

(B) unemployment is not normally concentrated in geographically isolated segments of the population

(C) the number of people who each know someone who is unemployed is always higher than 90% of the population

(D) Roland is not consciously distorting the statistics he presents

(E) knowledge that a personal acquaintance is unemployed generates more fear of losing one's job than does knowledge of unemployment statistics

 

答案：B.题目和上边一样，我选A。看了答案后，觉得B是在说，人口稀少的地方的人自然就知道哪些人失业了。A是说，5％是个一般的情况，我当时看到rarely有点犹豫，可是B的婉转和意境，当时太紧张了，怎么体会得到啊。

Q21.     p1-cr            59.            (34753-!-item-!-188;#058&007583)

 

A certain mayor has proposed a fee of five dollars per day on private vehicles entering the city, claiming that the fee will alleviate the city's traffic congestion.  The mayor reasons that, since the fee will exceed the cost of round-trip bus fare from many nearby points, many people will switch from using their cars to using the bus.

 

Which of the following statements, if true, provides the best evidence that the mayor's reasoning is flawed?

 

(A) Projected increases in the price of gasoline will increase the cost of taking a private vehicle into the city.

(B) The cost of parking fees already makes it considerably more expensive for most people to take a private vehicle into the city than to take a bus.

(C) Most of the people currently riding the bus do not own private vehicles.

(D) Many commuters opposing the mayor's plan have indicated that they would rather endure traffic congestion than pay a five-dollar-per day fee.

(E) During the average workday, private vehicles owned and operated by people living within the city account for twenty percent of the city's traffic congestion.

 

 答案：B.这题好多地方出现过，我还是错了，我选C.当时在B/C间犹豫，市长得逻辑是，进城费用贵，人们就不选择私家车。逻辑错误是，不是进城费贵，而是停车费贵，这是他因。我选C，虽然是削弱，但好像不是很直接，逻辑上不接。

Q38.     p1-cr            63.            (34945-!-item-!-188;#058&007591)

 

Companies O and P each have the same number of employees who work the same number of hours per week.  According to records maintained by each company, the employees of Company O had fewer job-related accidents last year than did the employees of Company P.  Therefore, employees of Company O are less likely to have job-related accidents than are employees of Company P.

 

Which of the following, if true, would most weaken the conclusion?

 

(A) The employees of Company P lost more time at work due to job-related accidents than did the employees of Company O.

(B) Company P considered more types of accidents to be job-related than did Company O.

(C) The employees of Company P were sick more often than were the employees of Company O.

(D) Several employees of Company O each had more than one job-related accident.

(E) The majority of job-related accidents at Company O involved a single machine.

 答案：B.我选D。D没有比较，不知道是否削弱题目。B是说公司P吧更多得事故认为适合工作相关，自然统计口径不同，自然就多了。
