Question

GRE逻辑题，下面的题目帮我解答分析一下，谢谢：

10. Census data for Prenland show that unmarried
Prenlandic men in their thirties outnumber unmarried
Prenlandic women in that age group by about ten to
One. Most of these men do wish to marry. Clearly,
however, unless many of them marry women who
are not Prenlandic, all but a minority will remain
unmarried.
The argument makes which of the following assump-
tions?
(A) Emigration from Preland is more common
among women than among men.
(B) A greater proportion of Prelandic women
in their thirties than of Prenlandic men of the
same age would prefer to remain unmarried.
(C) It is unlikely that many of these unmarried
Prenlandic men will marry women more than
a few years older than themselves.
(D) Prenland has a high rate of divorce.
(E) Most of the unmarried Prenlandic men are
unwilling to marry women who are not
Prenlandic.

Answer 1

答案应当是E.
看一下最后一句：Clearly,however, unless many of them marry women who
are not Prenlandic, all but a minority will remain unmarried.所以可以推断出选E

除了直选法，我们也可以用排除法。

A:Emigration 未提及；B: prefer to remain unmarried,主观，错误 C: more than
a few years older,未提及；D:divorce,未提及

Answer 2

这是新G10套逻辑题里面的。正确答案是C
文章意思是 30岁未婚男性和30岁未婚女性是十比一。这些未婚男性都愿意结婚。所以，如果他们不是非P地方女性结婚的话，摆脱单身机会很小。

但是，有一种可能就是那些30岁男人可以和比自己大的P地方女性结婚，同样也很可能摆脱单身。

所以，前提必须是 那些30岁男人不愿意和比自己大的女人结婚。

E选项不对，E的意思是那些男人不愿意和非P地方女性结婚。这是题目中结论的假设，不是前提。
