7.( 逻辑题)
Even after numerous products made with artificial sweeteners became available, sugar consumption per capita continued to rise. Now manufacturers are introducing fat-free versions of various foods that they claim have the taste and texture of the traditional high-fat versions. Even if the manufacturers’s claim is true, given that the availability of sugar-free foods did not reduce sugar consumption, it is unlikely that the availability of these fat-free foods will reduce fat consumption.
Which of the following, if true, most seriously undermines the argument?
A several kinds of fat substitute are available to manufacturers, each of which gives a noticeably different taste and texture to products that contain it.
B the products made with artificial sweeteners did not taste like products made with sugar.
C the foods brought out in sugar-free versions did not generally have reduced levels of fat, but many of the fat-free versions about to be introduced are low in sugar.
D people who regularly consume products containing artificial sweeteners are more likely than others to consume fat-free foods.
E not all foods containing fat can be produced in fat-free versions.

关键就在这句嘛,大家看这是个因果句。原因有一条:given that the availability of sugar-free foods did not reduce sugar consumption, 是说既然无糖食品的消费都没减少,无脂食品也不会减少。他是说两者具有可比性,这是一条很重要的原因。题目说undermine,那么原因取非,就是说两者不具有可比性:既然无脂的吃起来和有脂肪的一样,那么无糖的和有糖的吃起来就不一样了。所以选B

亲 文章里说的是 不含糖的吃起来像糖的食物 没有使得大家买 糖 的量减少
那么为什么大家有了吃起来像糖的还买糖呢?
再看一下选项
只有b说明 是糖的代替物的问题
糖的代替物有问题 不代表 脂肪的代替物有问题
所以就符合题目要求了

即使在人工甜味剂制成的众多产品面世,人均食糖消费量继续上升。现在厂家介绍,他们声称有高脂肪的传统版本的口味和各种食物中的无脂肪版本。即使制造商的说法是真实的,鉴于无糖食品的可用性食糖消费量没有减少,这是不可能的,这些不含脂肪食品的供应将减少脂肪的消耗。
下列哪项,如果为真,最严重破坏的说法吗?
A一个多种脂肪替代品提供给制造商,使每个产品含有明显不同的味道和质地。
B人工甜味剂制成的产品,像用糖制成的没有味道的产品。
C食物带来的无糖版本一般都减少脂肪含量,但不含脂肪的版本即将介绍的许多低糖。
D人经常食用含有人工甜味剂的产品比其他人更容易消耗脂肪的食物。
E并非所有含有脂肪的食物,可以生产不含脂肪的版本。
排除A,B,E。。二选一。。你看着办
