Sulfur dioxide, a major contributor to acid rain, is an especially serious pollutant because it diminishes the respiratory system's ability to deal with all other pollutants.

A. an especially serious pollutant because it diminishes the respiratory system's ability to deal

B. an especially serious pollutant because of diminishing the respiratory system's capability of dealing

C. an especially serious pollutant because it diminishes the capability of the respiratory system in dealing

D. a specially serious pollutant because it diminishes the capability of the respiratory system to deal

E. a specially serious pollutant because of diminishing the respiratory system's ability to deal

答案是A。我觉得C也没有问题，是因为太冗杂了吗？但是GMAT不是优先 n of n 的格式吗？

有木有牛牛来解答一下！？

LaurenceG

capability to do或capability of doing，没有in doing。

especially & specially 有细微的差别，但是在牛津词典中用especially更为普遍，此处specially起强调作用。
capability to do sth, capability of doing sth, 没有capability in doing sth.
另外在GMAT语法中，无生命的倾向于运用 A of B 的形式，一般不倾向于用A·s B 的形式
但是这个也只是一个有效性错误，也就是说，当五个选项中全是A·s B 时，这个语法因素就要排除出考虑范围
