请教一道题！

In many surveys, American consumers have expressed a willingness to spend up to 10 percent more for products that are ecologically sound. Encouraged by such surveys, Bleach-O Corporation promoted a new laundry detergent, Bleach-O Green, as safer for the environment. Bleach-O Green cost 5 percent more than typical detergents. After one year, Bleach-O Green had failed to capture a significant share of the detergent market and was withdrawn from sale.

Which of the following questions is LEAST likely to be relevant in determining the reasons for the failure of Bleach-O Green?

(A) How effective as a detergent was Bleach-O Green?

(B) How many other detergents on the market were promoted as safe for the environment?

(C) How much more did Bleach-O Green cost to manufacture than ordinary detergents?

(D) To what extent did consumers accept the validity of Bleach-O Green advertised and promoted to consumers?

(E) How effectively was Bleach-O Green advertised and promoted to consumers?

答案是C。这几个选项真是比较难取舍。谁给分析一下？

没人帮忙？

这道题目我是这样解的，请大家指教

分析题目：Why did the company fail to capture the market share? Find the least relevant explaination.

所以关键词是MARKET SHARE.

A. 有效不？ --自身原因

B。其他牌子？--其他因素影响结果

C。制造成本高？--就是它了，关键词是Market share, 与COST如何无关

D和E，都是讲ADVERTISEMENT 与market share有关

所以选C。

我做题时也常常碰到很难取舍的，后来发现很多时候是在读选项的时候思路被选项牵着走了。所以我觉得关键词跟相关性挺重要的。

谢谢yujia1122，这样解释更明确了！
