单选题 Couples blessed with strength and aggression ______ looks are better off having boys, as these characteristics are of more use to males.
A. other than B. rather than
C. rather too D. in spite of

【正确答案】 B

【答案解析】[解析] 选项：rather than的意思为“而非……，替代……”，如：We'll have the meeting in the classroom rather than in the auditorium．(我们与其在礼堂里开会，不如在教室开会。)句意：比起长相好的夫妇，那些体力更强、更有进取心的夫妇更容易生儿子，因为这些特质对男性更有用。故选B。
其他三项分别意为：other than不同于；rather too稍微；in spite of尽管。
