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.

請問一下答案為什麼是(A)?其他答案到底錯哪裡呢?

這題可以態度來切入.
R: 報告一個消息 alarming
S: But 蠻正常啊!
正確選項經常反向敘述: (A) not abnormal = normal
(B) not moderate 和 S 的態度不合
(C) S 沒有做 at least 5% 的假設
(D) R 引用的人沒說實話,跟 S 已經無關了,因為 S 是根據 R 做出回應
(E) 天馬行空
