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
答案为A
请问选项C错在哪里呢? 谢谢
同问,请大家讨论一下.
我觉得A B都可以
A, can compensate-> 可以吃人造肉,同时补充V就可以了
cannot compensate->则不能吃人造肉了
B, those V that is absobed by artifical meat, if present in the food-> we cannot eat artifical meat
those V that is absobed by artifical meat, if not present in the food-> we can still eat artifical meat

NN能帮解释一下A为何对么?
A翻译成:是否增加一个人的维生素的摄入能补偿这种人造脂肪的作用。?
那么如果能补偿怎么样,不能补偿怎么样呢?
没有想清楚。
我觉得还是要看题干:
In evaluating the columnist's position, it would be most useful to determine which of the following?
columnist's position is : 人工脂肪吸收了维他命 -> 导致身体吸收不到维他命.
C说人体摄取脂肪太低对身体会有危险.
这样看就很明显了
第二遍了,还是不懂,抓狂中,nn现身吧。
虽然看来看去,没有比A更好的答案了。但A的关系还是没搞懂。
我也选了B开始,不过刚看了看,觉得还是A对,B与结论无关
结论是不要食用人造fat,因为它会吸收人体所需的维他命。
A:是否增加维他命可以弥补人造fat的影响? 若回答是,那么结论就被削弱,若回答不是,那么结论被加强。 因此A选项的问题会直接影响结论,所以很好的evaluating了columnist's position.
B:是否被人造fat吸收的维他命存在于含有fst的食物中? 无论回答是还是否,对结论都没有直接的影响。因此无关

如果可以补偿,那么食用这种artificial fat不会影响到人体对vitamin的吸收(前提是要compensate),从而weaken了Columnist的argument
如果不能补偿,则说明无论如何食用这种artificial fat都会影响到人体对vitamin的吸收,从而strengthen了Columnist的argument
