A. an especially serious pollutant because it diminishes 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，  C错在哪？A 中respiratory system’s capability 看上去不是OG中的典型错误吗？看了以前的贴还是没有答案，请指教！

谢谢先！

那就是说在没有最好的，只能选更好的了？就讲究A了，是吗？

A 中是the respiratory system’s ability to 不是system's capability 是粗心没看清把！

另补：especially here means to particularly great degree. 例如，an especially difficult problem

special 强调different,unusual

specially: is usually used when you do sth that is different from what you usually do for a particular purpose.

I chose D.

system's in A.B. E is unidiomatic.

and for "Capability" we usually say:
capability to do sth.
capability of doing sth.
capability in sth.
therefore, C is unidiomatic too.

but the answer is A. and usually we say can>able to> ability > capability , but anyway, grammar is first, and then efficiency in SC.

I pick D
