Which of the following most logically completes the argument?

The irradiation of food kills bacteria and thus retards spoilage. However, it also lowers the nutritional value of many foods. For example, irradiation destroys a significant percentage of whatever vitamin B1 a food may contain. Proponents of irradiation point out that irradiation is no worse in this respect than cooking. However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since _______.

正确答案: E

which of the following most logically completes the argument?

the irradiation of food kills bacteria and thus retards spoilage. However, it also lowers the nutritional value of many foods. For example, irradiation destroys a significant percentage of whatever vitamin B1 a food may contain. Proponents of irradiation point out that irradiation is no worse in this respect than cooking. However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since___
A many of the proponents of irradiation are food distributors who gain from foods' having a longer shelf life
B it is clear that killing bacteria that may be present on food is not the only effect that irradiation has
C cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods
D certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is
E for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded


结论应是However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since___吧
也就是说irradiation和cooking比较是不应该的


答案和题目中的since much irradiated food is eaten raw我都不是很理解···求大牛解答







看了各位大牛解答之后我的想法
1,因为大多数irradiated food是生吃的,所以不能和cooking比较
这是因为如果这些食物不被irradiated,那么它们其实也不会被cooking,所以对于这些食物,不能引入cooking

2,对于需要cooking的食物,不能和cooking比较
这是因为,如果cooking的过程中包括了irradiation对食物的毁坏作用,两者效果叠加后必然大于单一效果,此时不能比较两个因子的大小。也就说x+y>x是必然成立的,推不出x和y的大小关系

我想的是前面说cooking比irradiation更糟 这句说这个说法不对
也就是后面要为cooking辩解一下了 答案就在CD中选
D certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is
这是在说cooking很糟糕 所以就不选它了
至于选C的道理是什么 我也不明白

不要告诉我这道题不是选c阿

è
conclusion: this fact is misleading总之是反对proponents, conclusion应该关于nutritional value/vitamin B1

注:NI表示new information(argument中没有出现过的信息)

A.many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life

èNI是关于proponents的,无关conclusion内的关系

B.it is clear that killing bacteria that may be present on food is not the only effect that irradiation has

èNI (quality bacteria,只是原文的一个信息点,一个用来解释说明情况的detailconclusion没有任何的关系

C.cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods

èNI(用实例解释反对的观点proponents)但是所讲得内容,却和argument中心谈的因素,也就是结论因素destroy nutritional value/vitamin B1无关è关键点就是要知道conclusion/argument主要论述的是什么内容,虽然会有很多的details的细枝末节,但是要分清楚,什么是主要的信息因素,什么是次要的

D.certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is

è看起来真的像是weaken了,因为证明了irradiation of food好,但是certain kinds of 不能用,因为属于特例,support不能用特例来证明

E.for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded

è这个答案虽然不是完美的support,但是却是唯一和argument/conclusion主要因素有关的

论理由E不是最好的,但是却是相对比以上4个最好,最和argument/conclusion有关的了

谢谢大牛解答!但是能不能再说的详细一点??

first, conclusion是说the fact(在vb1方面,irradiation不会比cooking的破坏更大)is beside the point and misleading吗?

second, 为什么说since irradiation food is eaten raw, 就能说明fact beside the point?
不就是因为irradiation food没有烹调过,才能和cooking这个过程相比较么?如果irradiation food 也要cooking,那就比不了啊。

如果生按照答案想的话,那就是说因为irr 都生吃,所以比非irr生吃糟;如果都烹调,那糟糕程度变两倍。
如果真是这么想的话,那这题也太木有逻辑了吧……
