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

为什么选C啊？现在到底是哪一年啊？1982年这个年份说明什么？C选项中的PERIOD是不是包括1982年啊？多谢帮助。

加强就是假设桥梁.

文章里表明了两个数字，将这两个数字比大小，一个是ADOPTION的数字，另外一个是想要收养孩子的夫妇的数字，但是文章的结论是可以被收养(而不是已经被收养)的孩子的数量要远少于收养夫妇的数字，那么加强就把ADOPTION的数字和可以被收养的数字联系在一起就可以拉。C说两个数字相等，也就是说，AVAILABLE的数字是可以和收养夫妇的数字进行比较得出CONCLUSION的.

至于1982毫无关系.
