Columnist:  eople 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 thecolumnist's position, it would be most useful to determine which of thefollowing?

(A) Whetherincreasing one's intake of the vitamins can compensate for the effects of theartificial fat
(B) Whether thevitamins that the artificial fat absorbs are present in foods that contain thefat
(C) Whether havingan extremely low fat intake for an extended period can endanger the health
(D) Whether thereare any foods that cannot be prepared using the artificial fat as a substitutefor other fats
(E) Whether peopleare generally able to detect differences in taste between foods prepared usingthe artificial fat and foods that are similar except for the use of other fats

 若增加维他命不能补偿被吸收的哪一步分，则人工fat有不可弥补的缺点，不应该用
