问题 No one can be licensed as an electrician in Parker County without first completing a certain course in electrical safety procedures. All students majoring in computer technology at Parker County Technical College must complete that course before graduating. Therefore, any of the college’s graduates in computer technology can be licensed as an electrician in Parker County. The answer to which of the following would be most helpful in evaluating the argument?
选项 A、Is a college degree a requirement for being licensed as an electrician in Parker County?
B、Do all students majoring in computer technology who complete the course in electrical safety procedures at Parker County Technical College eventually graduate?
C、Is completion of a course in electrical safety procedures the only way a person licensed as an electrician in Parker County can have learned those procedures?
D、Is a period of practical apprenticeship a requirement for becoming a licensed electrician in Parker County but not for graduating from the college in computer technology?
E、Do any of the students at Parker County Technical College who are not majoring in computer technology take the course in electrical safety procedures?
答案D
解析 本题为1993年10月GRE国内考题的一道逻辑推理重考题(见本书336页12题)，但问题目的与选项都有较大变化。这反映出国内考题重考的命题侧重点。本题推理为：完成用电安全程序课程是在Parker郡成为电工的一个必要条件，但段落最后一句话明显认为完成用电安全课程是成为电工的充分条件，而(D)提出实习期是否是成为电工的一个必要条件。若回答yes，则上面推理被削弱；若回答“no”，则对推理作出支持。所以(D)正确。
