  The popular notion that teachers are generally apathetic about microcomputer technology is false, or at least dated: a recently published survey indicates that 86 percent of the 5000 teachers who responded to survey questionnaires expressed a high level of interest in microcomputers.

  Which of the following, if true, would be most damaging to the argument above?

  A:No matter was made in the survey to determine whether the teachers who received questionnaires with microcomputers.

  B:Teachers who are interested in microcomputer technology were more likely than others to complete and return their questionnaires.

  C:Questionnaires were sent to teachers without regard to their areas of subject-matter expertise or teaching experience.

  D:There have been several important developments in the classroom applications of microcomputer technology since the survey results were tabulated.

  E:The survey was conducted as part of a marketing study by a company that manufactures and sells microcomputers.

  最佳解析:

  本题推理为:“由回答调查问卷中百分之八十六的老师对微机技术感兴趣,所以老师对微机技术漠不关心是不对的。”论据为回答调查问卷的百分之八十六的老师的态度,这个推理要想成立,必须基于的假设是“这些老师是所有老师的代表”,反对针对其论据说明,这些老师是特殊的,不能代表general。(B)说明对微机技术感兴趣的老师更可能完成和交回答卷,达到了这一目的,所以(B)is correct。(A)和(C)中这些老师是否有微机经历及答卷是否考虑到老师的专业技能都不能达到反对前提的效果,所以都不对。而(D)和(E)与前提无关。(A)起到了支持的作用。

  答案:B
