118.  The World Wildlife Fund has declared that global
warming, a phenomenon most scientists agree to be
caused by human beings in burning fossil fuels, will
create havoc among migratory birds by altering the
environment in ways harmful to their habitats.
(A)  a phenomenon most scientists agree to be
caused by human beings in burning fossil fuels,
(B)  a phenomenon most scientists agree that is
caused by fossil fuels burned by human beings,
(C)  a phenomenon that most scientists agree is
caused by human beings’ burning of fossil fuels,
(D)  which most scientists agree on as a phenomenon
caused by human beings who burn fossil fuels,
(E)  which most scientists agree to be a
phenomenon caused by fossil fuels burned by
human beings,

答案是C，C前半部分看上去很顺眼，但是一看到by human beings’ burning of fossil fuels我就直接排除掉了。这种双重所有格在GMAT里不是wordy的吗？又是of 又是 ‘s 的。。。。。
不懂啊

求解释

我想说一句废话..... 这道题我会选择用排除法选C, 哈哈, 帮不到你, 不过做题时这样会比较快

这种重复是指对同一个词的修饰不能重复
C选项表示的意思分了两层
human beings' burning
burning of fossil fuels
所以并不重复

如果是burning of human beings' 就重复了

楼上说的对啊。。这就是双重所有格错了。。
