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

答案是A，请问B为何不对

问的是利弊权衡，A指出应分析是否可弥补缺点，是否compensate是关键；

B光存在不够，应该研究是否能足够弥补缺少的维生素才行。

文中说这种人造fat会吸收维生素：这个是定下来的，无论维生素存在于这种人造fat中。

那么吸收就肯定是从人身上吸收，这个就会造成人对维生素的缺乏。

换一个角度说：evaluate的题目是对于选项的两种不同的回答会对文章有两种不同的效果：

如果人造fat中含有维生素，但是文中还是说它要吸收维生素，造成人体的缺乏。

如果人造fat中不含维生素，文中说它要吸收维生素，造成人体的缺乏。

综合上面，没有任何的结果上的区别。

对于A，能补充，就不会造成人体缺乏；不能补充，就会造成人体的缺乏……

不知是否解释清楚了

"the fat intaked by person中是否含有vatamins"对于"artificail fat吸收这些vatamins的事实"是不够成影响的。假设一个不恰当的比方，相信LZ应该容易理解。：

有些人喜欢吃苹果，有些人喜欢吃梨。某天某个报纸上的专家说了，吃苹果不好，虽然没有毒，但它会吸收掉人体内必须的维生素A,B,C,D,E,F,G...，这样人就缺乏营养了。

B答案说"要看梨里边是否含有维生素A,B,C...".其实不管梨里有没有这些玩意，是要它不影响身体的吸收就可以了。

In evaluating the columnist's position, it would be most useful to determine which of the following?

这句话到底是说：选型对分析观点有帮助，还是观点对分析选项有帮助？

TKS！

 It would be useful to determine...in evaluating the columnist'x position.

下列...对Columnist的观点进行evaluate.

Although the artificial fat, which can be used in place of fat in food preparation,文章说人工脂肪可在食物烹饪的时候充当脂肪，

那B说：维生素在含脂肪的食物里，这和文章说的对不上，文章没有反对B的说法，因此没有什么意义。细细体会

我怎么觉得是C啊，缺乏脂肪可能导致严重后果（意思是说这比少点维生素更严重），

这样的话，脂肪该吃还得吃，

A坏，B更坏型题目
