请教prep2008 SC 243题-关于所有格的用法

MsL

下面这道题的正确答案为A。
我不记得在哪里看到过讲解说：有生命的所有格用's，没有生命的所有格用of。
这里system是没有生命的，可以用system's ability这种表达？

243. (GWD-10-Q8)
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

答案里面解释：        
sth’s ability可用在无生命主体:
Additional evidence was provided by negative findings: drugs called adrenergic antagonists, which block peripheral adrenaline receptors, disrupted adrenaline’s ability to regulate memory but did not affect memory enhancements produced by glucose that was not stimulated by adrenaline.

请问只有在sth's ability 上面可以使用's，其他的都不可以？还有没有其他的特殊情况？
