Sharon: But a normal, moderate level of unemployment is 5 percent, with one out of 20 workers unemployed. So at any given time if a person knows approximately 50 workers, one or more will very likely be unemployed.
76. Sharon's argument is structured to lead to which of the following as a conclusion?
(A) The fact that 90 percent 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 percent 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 percentage, the actual percentage of those without jobs is even higher.
答案是(A), 我想問, 為什麼Sharon的argument可以帶出這個結論呢? if a person knows 50 workers, one or more will very likely be unemployed ---> 這句話有什麼特別含意嗎?
77. 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 percent of the population.
(D) Roland is not consciously distorting the statements he presents.
(E) knowledge that a personal acquaintance is unemployed generates more fear of losing one's job than does knowledge of unemployment statistics.
答案是(B), 想問為什麼不是(A)呢?
(B)代表的是什麼意思呢? 是否可幫忙做一個較詳細的解釋?
