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 percetage 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 it either beside the point,since much irradiated food is eaten raw,or else misleading,since___________
答案是E,for food that is both irradiated and cooked ,the reduction of vitamin B1 associated with either process individually is compounded.
我一直弄不明白所谓的irradiation is no worse in this respect than cooking是神马意思？是说经过辐射杀死的B1和做饭杀死的B1一样多或者更少？那E是什么意思，两个事实上一样多？
真心不明白，求指点啊，谢谢了

试着解释一下：
propnents说：（这里我认为有个assumptions是最后都要cook的，这个非常tricky）irradiation的food后面再cook一下，跟只cook最后剩的b1一样多，所以你们不要讲irradiation不好。
反驳说：1. 不知道你在讲点什么，一般irradiation后的food都是生吃的，不会再cook，讨论这个没有意义
2. 就算要讨论这个，你说的是错的，又irrad过的，又cook过的，消灭B1的数量大大增多

也可用排除法: AC先排除，B的话根本没有就有在讲B1，与中心无关；D是strengthen，而这个题目是要weaken P的说法；只剩下E
