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

(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
A选项的错误？

句子结构：The success… has stimulated experts to pursue…
　　To pursue something是不定式作补语，后跟定语从句(省略了关系代词that)。
　　考点：习惯用语、简洁有效、逻辑表达
　　习惯用语-such as，表示举例时用such as，而不是用like。
　　简洁有效，谓语动词后直接加形容词作补语;如果能用名词替代一个名词性从句，优先选名词(比如something, probability, likelihood等)。
　　逻辑表达，原句的插入语不能随意改为句中并列的成分，会使表达意思改变，而且有些动作是不可能用and连接同时发生的，如本题中的control和eradication。
　　(A) something代替名词从句，简洁;the other结构不完整，应该是one… the other搭配。
　　(B) consider a possibility表达方式不及直接跟形容词简洁有效;such like搭配错误，应该是such as。
　　(C) 正确，if not eradication是插入语，such as…举例。
　　(D) consider应直接跟形容词，a previous possibility表达错误且改变了原意;control and perhaps eradication不符合逻辑，改变了原句意思;possibility与perhaps语意重复;other用错，没有搭配对象。
　　(E) the possibility of what用法错误，应该用that;possibility与possibly重复;control and eradication不符合逻辑;用like表示举例错误。
　　补充说明：
　　one… the other 只有两个 some… the others 有三个以上
　　one… another，another… some… others，others… others = other people/things the others = the rest 剩余的全部

另外，刚才我也问道的问题，what做宾语不合适
