(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 presenc
answer:C
看了它的解释，说是代词it指带问题，这里的it是指condition吗？

这题考的是indicate that 后面的从句正确与否。c : it(the condition) is present when it(the condition) is not (present).

eyesy，其实我也明白，可是OG我已经作了N遍了，但这道题我也错了N遍了！不过还是要谢谢你！

bigmouse,我觉得这题的考点在于,同一个名词就用一个代名词指代,清楚俐落.
所以ab都不选,因为 it 和 one 都是指condition.

请问it为什么不能指代medical test ？

我觉得有it来指代在这里比one要清楚。ETS好像不是很喜欢用one来指代前面的名词，因为太vague。这样就排除了A和B。而its presence不如动词present干净明白，而且用在这里和前面的is present结构不对等，所以排除D和E。

同意BABYFACE的见解

其实will fail to detect a condition when...and indicate sth when... 我感觉更对称一些.

我想indicate its presence 不如indicate that it is present 是因为 最后的 when it is not 后承前省略了present, 用indicate that it is present when it is not 比较通.
