把C的论述运用到８２年的数据，就是说成功收养数和需要收养的儿童基本持平在50,000，而那一年愿意收养的夫妇达到两百万，因此是加强。

儿童数量是关键。反之，如果有选项说每年需要收养的儿童都至少有两百万，那就会削弱结论。

首句说结论: There are far fewer children available for adoption than there are people who want to adopt

说这里available adoption少于想要adopt的夫妇的数量.

后面的论证是用了这样一句话:there were only some 50,000 adoptions

要注意available adoption和adoptions之间的区别.

选项C就是一个架桥:available adoption = adoption

所以起到了加强作用
