99. Which of thefollowing most logically completes the argument?
The irradiation of food kills bacteria andthus retards spoilage. However, it also lowers the nutritional value of manyfoods. For example, irradiation destroys a signi?cant percentage of whatevervitamin B1 a food may contain. Proponents of irradiation point out thatirradiation is no worse in this respect than cooking. However, this fact iseither beside the point, since much irradiated food is eaten raw, or elsemisleading, since .
(A) many of theproponents of irradiation are food distributors who gain from foods’ having alonger shelf life
B) it is clear thatkilling bacteria that may be present on food is not the only effect thatirradiation has

 

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

(C) cooking is usually the ?nal step inpreparing food for consumption, whereas irradiation serves to ensure a longershelf life for perishable foods
(D) certain kinds ofcooking are, in fact, even more destructive of vitamin B1 than carefullycontrolled irradiation is
E) for food that is bothirradiated and cooked, the reduction of vitamin B1 associated with eitherprocess individually is compounded

我主要不太明白题目最后一句，为什么说那句话偏题了呢，either beside the point这句话怎么理解，还有误导何解？

如果理解答案的话，题目应该是想说有两种情况，一种是irradiation食物生吃，还有一种就是irradiation食物熟吃，生吃是两种lower比较，熟吃的话就要考虑两种lower叠加了吧。。。可以这么说么。。求解

yes, your anlysis is right.

But the error you commit is that you regard either beside the point is a whole phrase, actually either...or...is the construction of this sentence! If you recognise this point, I think it is much more clear to you.

The argument says"beside the point" because for the food eaten raw there is a choice between irradiation and no irradiation rather than between irradiation and cooking.

"misleading" because "irradiation is no worse in this respect than cooking" sounds like that irradiation is a better way than cooking(this actually also indicate a choice between irradiation and cooking ), but for the food cooked there is a choice between cooking+irradiation and cooking rather than between irradiation and cooking.

Option E eliminates the possibility that the effect of  cooking+irradiation will works in some other way.

So, it makes no sense to compair irradiation with cooking in the ways they work either separately or together.

这个解释比OG上的官方解释好懂多了，谢谢！！

同疑问。正确答案是E。为什么要考虑cooking和radiation combine在一起的情况呢？
