(A) they began to grow again after the 1991 report that linked moderate consumption of alcohol, and particularly of red wine, with a reduced risk of heart disease
(B) after the 1991 report that linked a reduced risk of heart disease with a moderate alcohol consumption, particularly red wine, they began growing again
(C) in a 1991 report, moderate alcohol consumption, and particularly of red wine, which was linked with a reduced risk of heart disease, caused them to begin to grow again
(D) with a reduced risk of heart disease linked in a 1991 report with moderate alcohol consumption, in particular red wine, they
began growing again
(E) a reduced risk of heart disease linked to moderate alcohol consumption in a 1991 report, and in particular red wine, started them growing again
这道题的c选项，OG上的解释说which 错误地指代了 red wine, 但是这里有一个of 结构，为什么不可以看成 which 跳跃指代 consumption ？作者: popup 时间: 2014-10-1 23:13
是这样的，关系代词which一定是优先指代前面紧挨着的名词，只有当which前紧挨的名词和which后的动词在单复数上不匹配的时候，which才能往前跳跃指代，不然只能老老实实指代前面紧挨的名词，这是gmat语法的规则。
Eg：New hardy varieties of rice show promise of producing high yields without the costly irrigation and application of commercial fertilizer that were required by earlier high- yielding varieties. 例子中that前的fertilizer是单数，但that后的were是复数，所以that只能被迫往前跳跃指代irrigation and application
类似的，如果关系代词指代人/物错乱，也只能被迫跳跃指代。
Eg：She participated in the hearings on the impeachment of President Richard Nixon, which were televised nationwide. 跳跃原因：which不能指代人，而且were复数，所以指代hearings无歧义
