Columnist: People should avoid using a certain artificial fat that has been touted as a resource for those whose medical advisers have advised them to reduce their fat intake. Although the artificial fat, which can be used in place of fat in food preparation, has none of the negative health effects of fat, it does have a serious drawback: it absorbs certain essential vitamins, thereby preventing them from being used by the body.
In evaluating the columnist's position, it would be most useful to determine which of the following?

In evaluating the columnist's position, it would be most useful to determine which of the following?
(A) Whether increasing one's intake of the vitamins can compensate for the effects of the artificial fat (B) Whether the vitamins that the artificial fat absorbs are present in foods that contain the fat (C) Whether having an extremely low fat intake for an extended period can endanger the health (D) Whether there are any foods that cannot be prepared using the artificial fat as a substitute for other fats (E) Whether people are generally able to detect differences in taste between food 以前的解释都说B无关,可没有说为什么。 为什么B无关? 回答是:人造脂肪会吸收那些特定的维生素,从而影响人体吸收。 回答否:举个例子,比如人造脂肪吸收维生素C,柠檬里有维生素C,但是人们食用柠檬时从来不用人造脂肪,所以不会影响人体对维生素C的吸收。 哪错了呀? 请指教,谢谢!
我觉得无关不无关倒不是关键 此题的关键是原句it absorbs certain essential vitamins, thereby preventing them from being used by the body. 选B可能是考虑到如果吸收自己带来的V那么就不会消耗体内的V了 但是原句并没有分是体内的还是摄入的,只是说防止absorb就不行,所以B其实是违反了原句的
