Q12:

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 _______.

1. many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life
2. it is clear that killing bacteria that may be present on food is not the only effect that irradiation has
3. cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods
4. certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is
5. for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded

The correct one is E. why?

Were the explanation acceptable, it would compound the reduction of V B.
    

我还是不明白。

翻译一下原文：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 _______.

irradiation毁坏了bacteria。还降低了营养。例如：irradiation破坏了VB1.   irradiation支持者指出irradiation没有cooking更糟糕。但是，事实是生吃含有irradiation的食品在两个观点之外，或者，两者同时存在，无法区分原因，误导了。

我不明白，生吃含有irradiation的食品---beside the point？两者同时存在misleading？

GWD-5-Q30:

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 _______.

1. many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life 支持者是分晓商，所以观点偏颇。但观点偏颇并不是misleading

2. it is clear that killing bacteria that may be present on food is not the only effect that irradiation has 杀菌不是微波照射的唯一作用。无关

3. cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods  炒是料理事物的最后一个步骤，尽管微波照射让易腐的事物在货架上保持更久。与生吃的前提相反。并且是支持支持者的观点。

4. certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is （支持支持者观点）

5. for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded（对既照又炒的事物，他的B1的减少原因是复杂的。所谓复杂是，有可能是因为照射了一炒之后就全部损失了。也有可能因为照射了，炒的过程不会产生新的损失。所以用炒与之作比较是misleading的）

since much irradiated food is eaten raw, 生吃的东西没cooking, 但是irradiated照过了，不是就可以区别开来了吗？

A:much irradiated food is eaten raw, not cooking

B:irradiated and cooking

争议题。。。C/E之间大家争论不休，楼主可以去搜一下旧帖。
