There are far fewer children available for adoption than there are people who want to adopt. Two million couples are currently waiting to adopt, but in 1982, the last year for which figures exist, there were only some 50,000 adoptions.

Which of the following statements, if true, most strengthens the author’s claim that there are far fewer children available for adoption than there are people who want to adopt?

(A) The number of couples waiting to adopt has increased significantly in the last decade.

(B) The number of adoptions in the current year is greater than the number of adoptions in any preceding year.

(C) The number of adoptions in a year is approximately equal to the number of children available for adoption in that period.

(D) People who seek to adopt children often go through a long process of interviews and investigation by adoption agencies.（C）

(E) People who seek to adopt children generally make very good parents.

求解法，实在想不通，为什么是C！！！答案！！！

A/B/E 无关
D 和作者要证明的东西刚好相反（如果process很长，那么可能有很多小孩，但是家长要通过很多步骤才能完成adoption, 所以不能证明小孩很少)

C 的意思基本就是说只要有小孩，就能adopt, 那么如果这个条件成立，自然就证明小孩比家长少（小孩数量=adoption数量，adoption数量<家长数量 --> 小孩数量<家长数量)

说的是现在有2m夫妻想要领养。

后面给的数据是去年领养的数字。就算领养的数字=儿童的数字。不代表现在夫妻的数字>儿童的数字。

这是逻辑，又不是作文里的argument, 他只不过问你哪个会strengthen, 又不是问你哪个会让这个argument变得完美。。。

你就用货架上的商品来想吧

如果一个东西（小孩）一上货架，就被客户（领养父母）抢购一空，这说部说明供不应求？
这就是D，应该很明显是对的。

这里最迷惑的是A.
但仅仅说买东西的人排队很长，不一定表示某种商品供不应求啊，也许这个商品买起来很麻烦，也许收银台人手不够，也许商店出口太小，一次才能一个人进去买，反正不一定表示这种商品供不应求。
