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.  roponents 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 _______.

能解释一下吗？谢谢

不知不觉

"1。为何说beside the point: 因为对于 irradiated food that is eaten raw。不涉及到cooking的问题，所以拿rradiation 和cooking比较是无关的

2。为何说misleading：对于不是eaten raw的食物，支持者的话让人误解为irradiation是好的，比cooking好。但因为cooking对 irradiated food that is NOT eaten raw是必须的，而irradiation只是保鲜，不是必需的，可有可无。这在情况下，本来可以不用irradiation去保鲜，但proponents提的事实却让人误解为要irradiation，因为它不必cooking差。

3。从行文结构上讲，作者反驳支持者是采用将食物分两类：对于不需要cooking的食物，支持者的证据无关；对于需要cooking的食物，因为cooking是必需的，你没得选，而irradiation不是必需的，所以支持者的话让人产生了误解，说你必须选irradiation，因为它比cooking好。

4。对于E，无法让人误解什麽。"
