来自：Karenzz的解答！！赞今天纠结这道题很久，最后在王可达老师的公共主页上找到这道题的详解，贴上来， ...

考试的时候可以用排除法，但是我们现在是要来分析正确答案真正的原因，所以感觉根本没有达到讲解的目的！！！坑爹...

苏幕遮sang

感觉RON讲得好清楚啊，可以进行比较的前提是两者是可替代的，只要能攻击这个前提就可以了

下面是RON的原话：
when you get one of these questions, you should try to simplify the argument as much as you can. once you do that - get rid of as much "noise" and verbiage as possible - you should be able to answer the questions more readily.

in this case, here's a more "noise-free" version of the argument:

People have compared irradiation to cooking and found that they're about the same (in terms of leaching nutrients). Why is this comparison misleading?

(note that you're ONLY concerned with the "misleading" part, since that's where the blank is. the "beside the point" part DOESN'T MATTER AT ALL.)

--

so, you're looking for a reason why it's MISLEADING to COMPARE IRRADIATION TO COOKING.

when you COMPARE two things, the assumption is that they are ALTERNATIVES.

therefore, if a comparison is "misleading", we need a choice that shows that they aren't simply alternatives.

this is what choice (e) does: it shows that some food is irradiated AND cooked. they're not alternatives, so you can't settle the issue with a comparison.

--

analogy:
let's say that dieting burns MORE body fat than does exercise, all other things equal.

if i say "you should just diet, since exercise is no better than dieting", then that's MISLEADING.

why is it misleading?
because ... you can do both, compounding the effects.

same deal here.
