The success of the program to eradicate smallpox has stimulated experts to pursue what they had not previously considered possible--better control, if not eradication, of the other infections such as measles and yaws.

(A) what they had not previously considered possible--better control, if not eradication, of the other infections such as

(B) what they had not previously considered a possibility--better control, if not eradication, of such infections like

(C) something they had not previously considered possible-better control, if not eradication, of such infections as（答案）

(D) something not considered a previous possibility--better control and perhaps eradication, of other infections such as

(E) the possibility of what they had not previously considered--better control and possibly eradication of infections like


NN 们 帮我解释一下 C 比A 好在哪里了 C 的if not eradication 做什么成分 是不是省略呢？

A中的问题主要是“the other”和“such as”的用法。smallpox（天花）与后面的measles(麻疹) and yaws（一种热带皮肤病）的关系不应用“one,  the other”来分类。再次，从搭配上，such+Nouns+as才是常用搭配

cycyang

if not eradication, 在句中的成分应该是状语，意为“如果不是根除的话”，不影响句子主干。

我觉得是A 的the other有问题 the other infections 指除了smallpox 以外的所有，文中没有穷尽的意思吧

请问一下  你觉得我这样理解主题结构 对吗?  : 天花的根除 使得 科学家 去 追求对 诸如 麻疹 和 热带病 传染病 更好的 控制。
