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.

明白了。C说的是fat，而结论说的是“不要用artifical fat因为有副作用”，所以C与结论实质上无关。

想问一下为什么B不对？

phenomena

如果用artificial fat的话，那么就和含有fat的食物里含有的vitamin无关了，所以B是无关选项

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

B肯定是不对的，要评价的是食用人工油和维他命吸收之间的逻辑关系，B说的是维他命和食物之间的关系，离吸收还好几步呢

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
