标题: 大全115,看了老帖子还是困惑,恳求大家帮帮我~

115. Any medical test will sometimes fail to detect a condition when it is present and indicate that there is one when it is not

A. a condition when it is present and indicate that there is one

B. when a condition is present and indicate that there is one

C. a condition when it is present and indicate that it is present

D. when a condition is present and indicate its presence

E. the presence of a condition when it is there and indicate its presence

正确答案选C，大全解释说AB里的it指代不明，从题目中看，it这里不是很很明显指代a condition吗？为什么会不清楚呢？而且旧帖子说这里出现了第二个指代词，在哪里啊？http://forum.chasedream.com/dispbbs.asp?boardid=23&replyid=169463&id=22843&page=1&skin=0&Star=1

谢谢大家帮助！

我觉得AB错在one上。one不能指代condition。因为condition有两种情况（present和 not present），所以如果one 指代condition会有逻辑错误。
