Columnist:  People should avoid using a certainartificial fat that has been touted as a resource for those whose medicaladvisers have advised them to reduce their fat intake.  Although the artificial fat, which can beused in place of fat in food preparation, has none of the negative healtheffects 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'sposition, it would be most useful to determine which of the following?

(A) Whether increasing one's intakeof the vitamins can compensate for the effects of the artificial fat

(B) Whether the vitamins that theartificial fat absorbs are present in foods that contain the fat

(C) Whether having an extremely lowfat intake for an extended period can endanger the health

(D) Whether there are any foodsthat cannot be prepared using the artificial fat as a substitute for other fats

(E) Whether people are generallyable to detect differences in taste between foods prepared using the artificialfat and foods that are similar except for the use of other fats

我感觉AB选项都对，但是A是正确选项。

A, can compensate-> 可以吃人造油，同时补充V就可以了

   cannot compensate->不可以吃人造油

B, those V that is absobed by artifical meat, if present in the food-> 不可以吃人造油

   those V that is absobed by artifical meat, if not present in the food->可以吃人造油

希望大神能解释一下

我对B的理解不是这样的啊。
我理解的是：那些能被人造黄油消耗的维生素，是否出现在含有脂肪的食物中？
the vitamins（ that theartificial fat absorbs） are present in foods（ that contain the fat）

然后我觉得，题目要求我evaluate的是：人造黄油消耗V，阻碍吸收 -> 不要吃人造黄油。关键还是V的吸收。
这些维生素出现在何处，不影响我对摄入人造黄油的好坏的评价，所以就把B踢了。

B选项Whether the vitamins that the artificial fat absorbs are present in foods that contain the fat：那些能被人造黄油消耗的维生素是否出现在含有脂肪的食物中。不管出不出现，人造黄油都会消耗维生素，没有办法解决问题，改变结论
