   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.

关于 A。和 C。 ， 觉得 A 加强，为什么不对 ？ 还有 c 怎么理解

C是架了一个桥。

原文：结论：供领养的孩子少于想领养孩子的人。证据：去年有200万想领养，但只有5000个成功的adoption。

论据中的adoption和结论里的供领养的孩子什么关系呢？C架了一个桥，做了联系，所以加强。

A中想领养的人多无法加强结论，得不出供领养孩子和想领养孩子的人谁多谁少，可能供领养的孩子远远多于想领养孩子的人，只是由于某种原因成功领养的案例很少。缺C的桥梁。

c   The number of adoptions in a year is approximately equal to the number of children available for adoption in that period

c 说：孤儿的数量 和 能够被领养的数量一样多。

然后怎么 架桥了？ 解释一下，谢谢。

因为“供领养的孤儿的数量 和 能够被领养的数量一样多”加上“领养的数量（50000）少于想领养孩子的数量（2 million）”

所以“供领养的孩子少于想领养孩子的人”

简化：结论：X<Y,证据：Z<Y.问：加强?

C:X=Z。   因为Z<Y且X=Z 所以X<Y.

谢谢 我知道了。 读题 的时候 忘读 时间状语了。所以 总是想现在 的怎么和过去的比。。 谢谢shzzhengfan

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