Recent research indicates that two popular arthritis drugs are possibly not as safe as they initially believed.

(A) that two popular arthritis drugs are possibly not as safe as they initially believed

(B) that two popular arthritis drugs may not be as safe as they were initially believed to be

(C) two popular arthritis drugs to possibly not be as safe as it was initially believed

(D) the safety of two popular arthritis drugs may not be as great as it was initially believed

(E) the safety of two popular arthritis drugs not to be as great as they were initially believed to be

答案是B。

有个细节不太明白。prep笔记的解释说选项D的it没有指代对象，个人认为可以指代the safety，不知道对不对，请大家帮忙~~~

it 是人称代词，指代前面所提到的事物本身.
打个不恰当的比方，前面如果提到的是lz，那么后面这个it就指代的是与被前面所提到是状态（比如身高体重等）完全一致的lz，而不是长胖了的lz
所以在这道题中用it 指代the safety 是不对的，因为该句子想表达的safety 在本质上是不一样的
