It has long been thought that high levels of the hor-
mone testosterone contribute to the onset of heart
disease in men．However, this view cannot be correct,
since men who have heart disease typically show
significantly lower levels of testosterone than do men
who have not had heart disease．
The argument above assumes which of the following？
(A)Many men who have never had heart disease
have unusually low levels of testosterone．
(B)Having heart disease does not significantly lower
the level of testosterone in men．
(C)Levels of hormones other than testosterone
significantly affect the likelihood that a man
will develop heart disease．
(D)Heart disease and lowered testosterone levels in
men are the effects of a single common cause．
(E)High levels of testosterone have never been
thought to contribute to a serious disease other
than heart disease．

第一句话说之前人们认为男性的雄性激素含量高会导致心脏病，第二句话是说有心脏病的男人雄心激素含量比没有心脏病的人的含量低很多。题目问的是这个Argument是基于什么样的假设？
我觉得这里需要的假设应该是B吧，就是得了心脏病之后并不会改变雄性激素的含量，这样才可以得出结论！
