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, one or more will very likely be unemployed.
下面举个栗子 Student representative: Our university, in expelling a student who verbally harassed his roommate, has erred by penalizing the student for doing what he surely has a right to do: speak his mind! Dean of students: but what you' re saying is that our university should endorse verbal harassment. Yet surely if we did that, we would threaten the free flow of ideas that is the essence of university life.
Which one of the following is a questionable technique that the dean of students uses in attempting to refute the student representative?
(A) challenging the student representative knowledge of the process by which the student was expelled (B) invoking a fallacious distinction between speech and other sorts of behavior (C) misdescribing the student representative' s position, thereby making it easier to challenge (D) questioning the motives of the student representative rather than offering reasons for the conclusion defended (E) relying on a position of power to silence the opposing viewpoint with a threat

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.
