OG13_101
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 are 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, sinc_____________________

(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 Bl than carefully controlled irradiation is
(E)    for food that is both irradiated and cooked, the reduction of vitamin Bl associated with either process individually is compounded

请大神帮我看一下E选项是什么意思吧,我看不懂啊,呜呜呜。。。

非大牛。
E选项大概是说对于又被irradiated(暂且理解为微波吧)又被cooked的食物来说,造成维他命B1减少的原因是复合的。也就是说,你怎么知道对这样的食物而言是cooking造成维他命减少呢?
作者要驳斥之前提出的微波至少不比cooking坏的态度,也就是对cooking是正态度,由此可排除D。

哇,正是造福人类啊,我看那解释苦想半天二楼一句话把我点醒了

我觉得 二楼解释的不太准确

E 选项的意思翻译的不对 ,应该是 : 对于既烹饪又辐照的食物来说,这两种伴随维他命B1减少的过程中任何一个过程,分别都是复合的

选这个题目,最关键是要,看对提干中,however那段话的结构

但是,事实要么跑题了,要么被误导了
跑题了,是因为有些辐照过的食物是生吃的
误导了,是因为。。。E选项

同意,我也觉得二楼的解释不太符合og的解释。og中reasoning的部分这样写:
"如果辐照和烹饪combine起来流失的Vb1比单独辐照流失的Vb1多,则能表明proponents是错的"
E选项的意思我理解的是:
对于既辐照又烹饪的食物来说,此时的Vb1的流失 在任何单独的过程(辐照或烹饪)中,都是有复合(作用的)。----对应上面reasoning的解释就是说combine使得VB1的流失 比 单独的辐照或者烹饪使VB1的流失 要多
