1、在GMAT中，because是优于because of的表达，将B和E排除掉；
2、习惯用capability of doing sth.来表达做某事的能力，所以C和D排除掉；
A为正确答案。
而且，D选项有歧义，用to deal可能让人误以为是为了deal with all other pollutants所以dininish the capability of the repiratory system。。。
对于这道题应该还有一些需要注意的地方：
1. specially 和especially区别
Especially is most often used to emphasize something, or to say that something is more worth mentioning or more important than the other things you are talking about: It can be especially difficult for drivers to see cyclists at night. | The town is especially crowded in the summer (=much more than in winter). I hate interruptions, especially when I'm trying to work (=I do not mind as much at other times).
Specially is usually used when you do something that is different from what you usually do for a particular purpose. It is often used with the passive form of a verb: a specially made/designed/adapted etc car | I bought it specially for you
2. capability和ability区别
至于ability to do和capability to do区别，我想可能在强调某人/物天生具有某种能力用ability好，capability可能强调的是能不能做某事（跟天生没什么关系），如government'capability或transport system's capability等。
1)If we don't take great care, SARS could become established in the poorest nations - places like Burundi, Nigera or Malawi - which have neither the high-tech capability of Toronto nor the totalitarian muscle of China to contain it
2)capability of sth. to be done表一种属性, 非一种主动的能力。
3. the respiratory system不是人,怎么可以用's结构?
GMAT中没有强行规定此点, 有很多这样的例子。如og268 Europe’s young playwrights
4. 较常见的一些表达
have the capability to do
the capability of doing
possibilities for/of (doing) something
ability/inability to do
