[求助]一道逻辑题,大家帮我看看

The simple facts are these: the number of people killed each year by grizzly bears is about the same as the number of people killed by lightning on golf courses. And the number of people killed by lightning on golf courses each year is about the same as the number of people electrocuted by electric blenders. All the horrible myths and gruesome stories aside, therefore, a grizzly bear is in fact about as dangerous as an electric blender or a game of golf.
Which one of the following, if true, would most effectively undermine the author’s argument?
(A) Although the number of people killed by lightning on golf courses each year is very small, the total number of lightning fatalities is many times greater.
(B) Electric blenders are among the safest household appliances; were the author to compare fatalities from electrical appliances in general, she would get a much higher figure.
(C) Most people would rather take their chances with blenders and golf games than with grizzly bears.
(D) Bears in general—including black, brown, and cinnamon bears, as well as grizzly bears—kill many more people than do electric blenders.
(E) Statistics show that the number of times people use electric blenders each year exceeds the number of times people play golf each year, which in turn far exceeds the number of contacts people have with grizzly bears each year.

我选C,答案是E。不太明白。谢谢大家!!

题目中指出的是the number of people killed by三样东西相同,因此这三样东西的危险性相同。

也就是说,这是绝对数量的比较。那么我们只要用相对数量进行削弱就可以了,即“被杀的人数/使用这三样东西人数”的比例不同。

答案E则是将此比例中的“使用这三样东西的人数或者次数”进行了比较,因此比例也就不同了。
