Questions 10-11

10. The labeling of otherwise high-calorie foods as "sugar-free," based on the replacement of all sugar by artificial sweeteners, should be prohibited by law. Such a prohibition is indicated because many consumers who need to lose weight will interpret the label "sugar-free" as synonymous with "low in calories" and harm themselves by building weight-loss diets around foods labeled "sugar-free." Manufacturers of sugar-free foods are well aware of this tendency on the part of consumers.

.

11. Which one of the following, if true, provides the strongest basis for challenging the conclusion in the passage?

(A) Food manufacturers would respond to a ban on the label "sugar-free' by reducing the calories in sugar-free products by enough to be able to promote those products as diet foods.

(B) Individuals who are diabetic need to be able to identify products that contain no sugar by reference to product labels that expressly state that the product contains no sugar.

(C) Consumers are sometimes slow to notice changes in product labels unless those changes are themselves well advertised.

(D) Consumers who have chosen a particular weight-loss diet tend to persist with this diet if they have been warned not to expect very quick results.

(E) Exactly what appears on a product label is less important to consumer behavior than is the relative visual prominence of the different pieces of information that the label contains.

答案 为什么是 b ? b是支持结论的, 是吧. 我觉得是a 才是weaken 了结论, 我错哪了 ?

A is somehow irrelevant to the argument and the conclusion.
What's stated in A is that how the manifacturer would respond to the ban on the products labels . But if you look back into the lines of the argument and conclusion, you could find out that the conclusion is pointed to that the ban should be excuted , which is the viewpoint of the author, in other words, the ban would have not been excuted or get its regime by the time the argument was expressed.  By understanding this key difference between what's being and what's not being, you could find out that A is certainly not relevant to the conclusion , not to say that A would have backforth influence on the conclusion.

On the other hand , what B is talking is really interesting and important at least to the diabetic patients, though bad news to the diet-foods customers.  why? you could look to the choice to find out why it would happen like that. B says that the free-sugar lable is very important to the diabetic patients who would rely on the labels on products to differentiate free-sugar foods from sugar-contain foods------the patients need to eat the free-sugar foods. If the ban took its power, all the free-sugar labels disappearing altoghter , the diabetic patients would not be able to differentiate the free-sugar foods.
Thus ,   at least because of this unconsiderable result, the ban should not be excuted.


hope it clearly.
