prep关于artificial fat那道

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?

(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 foods prepared using the artificial fat and foods that are similar except for the use of other fats

答案选A，我选的B。完全没有办法说服自己，请nn指点！

为什么没有nn帮忙指点迷津呢？这个可是prep的题啊……

难道大家都觉得没有解释的必要吗？汗……

B说有脂肪的食物里有没有会被人工脂肪所吸收的维他命

那些脂肪食物里有没有会被吸收的维他命和结论：人工脂肪会影响基本维生素的吸收，无关

有/无都不能说明结论被加强或者削弱
