问题 单项选择题

某国的人口调查数据表明,未婚的三十岁以上的男性超过这个年龄段的未婚女性,比例大约为十比一。这些男性中,大多数确实希望结婚。然而,明显地,除非他们中有许多人娶外国女性,否则大部分人将保持未婚。
上面论述基于下列哪个假设

A.移民到国外的女性比男性多
B.与该国男性相同年龄的三十几岁的该国女性宁愿保持未婚
C.大多数未婚的该国男性不可能娶比他们年龄大的女性
D.大多数未婚的该国男性不愿意娶非本国的女性

答案

参考答案:C

解析:这道题是先给出推论结果再选择假设条件。很明显ABD三项都不能得出题干结论,只有选项C是必须假设的,否则,许多该国未婚男性都愿娶比他们年龄大的女性,就不会必然得出“未婚的30岁以上的男性除非其中的许多人娶外国女性,否则大部分人将保持未婚”的结论。

Obama’s first (13) after the oil spill was to "feel the blame" rather than "feel the pain, " which are pretty sarcastic words as it were. No one intends to let British Petroleum (BP) management (14) the hook—for dangerously cutting corners, and for a (15) safety record.
