85．  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

首先 这句话的意思我没有弄明白 希望NN们指点一下

其次 and前后应该是对称的  那么 这个对称应该只是 从句+and+从句 还是要求两个从句的结构也必须对称呢?

“任何医疗检测有时候会产生这样的测试结果，当一种情况发生时，没有检测出来；或者当这种情况没有发生时，检测表明有这种情况。（第二种情况就是通常所说的假阳性）

至于前后对称，应该是在语法正确的前提下，对称越整齐越好吧。
