og15题：
In his research paper, Dr. Frosh, medical director of the Payne Whitney Clinic, distinguishes mood swings, which may be violent without their being grounded in mental disease, from genuine manic-depressive psychosis.
(A) mood swings, which may be violent without their being grounded in mental disease, from genuine manic-depressive psychosis
(B) mood swings, perhaps violent without being grounded in mental disease, and genuine manic-depressive psychosis,
(C) between mood swings, which may be violent without being grounded in mental disease, and genuine manic-depressive psychosis
(D) between mood swings, perhaps violent without being grounded in mental disease, from genuine manic-depressive psychosis
(E) genuine manic-depressive psychosis and mood swings, which may be violent without being grounded in mental disease
The best choice is C because it uses the idiomatically correct expression distinguishes between x and y and because it provides a structure in which the relative clause beginning which may be violent clearly modifies mood swings. The other choices use distinguishes in unidiomatic constructions. Additionally, their in A is intrusive and unnecessary, and the modifier of mood swings in B and D (perhaps violent) is awkward and less clear than the more developed clause which may be violent.
难道是说在ets看来distinguish between x and y比distinguish x from y更idiomatic？？可是我记得我做过有distinguish x from y正确的题。还请大家指正！

谢谢MM的指教！这两种用法都可以。只是在C中which may be violent without being grounded正确，而不是A中without their being grounded 的累赘用法。

我同意rabbitbug mm的说法，因为og解释中提到“ The other choices use distinguishes in unidiomatic constructions.”所以，应该在ets的眼中distinguish between A and B比distinguish A from B更符合语法规则。个人的一点意见，还请指正。
