一家航空公司说自己的维修率低于行业平均水平，由此得出说自己比行业其它公司更注重飞机的保养和安全。MingLiU","serif"; mso-bidi-font-family: "Times New Roman"; mso-fareast-font-family: SimSun; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">Weaken：这家公司的飞机已使用年份长于行业平均水平

基金答案好像是加强啦。是否应该是公司的飞机已使用年份低于行业平均水平，所以维修率低于行业平均水平。

请NN 赤脚。

题干问的是加强
            

三个无关选项不记得了：
            

C）seals and sea lions的食物大量减少，但是sea otters的prey没有减少（正确答案）
            

e) 在kill whale到不了的bay的sea otters数量和kill whale到的了的数量都减少了。
        

我觉得应该是E. 说明不是Whale 导致Sea Otters 减少，加强了是Disease 导致SeaOtters 的减少。

认同，c好像无关！题干没提到prey吧

同意e.

c更像无关选项.

sea otters的prey没有减少,既无法排除killer whales因素,也无法证明disease more likely.
