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 determinewhich of the following?
(A) Whether increasingone's intake of the vitamins can compensate for the effects of the artificialfat
(B) Whether thevitamins that the artificial fat absorbs are present in foods that contain thefat
(C) Whether having anextremely low fat intake for an extended period can endanger the health
(D) Whether there areany foods that cannot be prepared using the artificial fat as a substitute forother fats
(E) Whether people are generally able to detectdifferences in taste between foods prepared using the artificial fat and foodsthat are similar except for the use of other fats
答案A
题中思路：由于人工fat阻止了vitamin的吸收，所以人工fat并不好（drawback）。（虽然人工fat可以替代真fat，从而减少真fat 的吸收）。
提问：A项是在承认人工fat阻止vitamin吸收后提出的一个补救措施（若为真，可以抵消人工fat对vitamin吸收造成的影响），不是“评价”题目的方式。 |
