单选题 During his three years in office, the governor of a state has frequently been accused of having sexist attitudes toward women. Yet he has filled five of the nineteen vacant high-level positions in his administration with women appointees, all of whom are still serving. This shows that the governor is not sexist.
Which of the following statements, if true, would most seriously weaken the conclusion above?

A、 One of the women appointed by the governor to a highlevel position is planning to resign her post.
B、 The platform of the governor's political party required him to appoint at least five women to high-level positions.
C、 Forty-seven percent of the women who voted in the state gubernatorial election three years ago voted for the governor.
D、 A governor of a neighboring state recently appointed seven women to high-level positions.
E、 (E) The governor appointed two Black Americans, two Hispanic Americans, and one Asian American to high-level positions in his administration.

【正确答案】 B

【答案解析】[解析] 本题推理也是由一个事实“某州长在19个高层职位空缺中用了5名女性”，得出一个解释性结论“州长不是性别歧视者”。反对思路比较固定。如果党纲要求州长至少任命5名女性，如(B)所说，就从另外一个角度对上述事实提出解释，从而起到了反对作用，所以(B)正确。(A)中的“一就职高层的女性打算辞职”与“州长是否性别歧视”无直接关系，这名女性要辞职可以有许多原因；(C)讨论的“三年前”与推理毫无关系；(D)中的“邻州的州长”与我们探讨的“某州州长”无关；(E)支持了州长不是一个racialist，但与本题探讨的“是否性别歧视”无关。
