Even after numerous products made with artificial sweeteners became available,sugar consumption per capitacontinued to rise.
Now manufacturers are introducing fat-freeversions of the traditional high-fat versions.

Even is the manufacturers’ claim is true, given that the availability ofsugar-free foods did not reduce sugar consumption, it is unlikely thatthe availability of these fat-free foods will reduce fat consumption.



Which of the following, if true, most seriously undermines the argument?



b. the products made with artificial sweeteners didi 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 vesions about to be introduced are low in sugar.



正确答案是b，我感觉c也有道理，请教大家，这个做题的思考方式是怎样的？

这套题题干的论证方式是类比，作者由一个现象，虽然人造的的无糖制品的在市面上普及，但是人均糖的消耗量增加这样一个事实为前提，推出这样一个结论，即人造的无脂肪食品即使面世，但是人均脂肪消耗量仍然增加。 那么如果当无糖制品与含糖食品的味道差距太大的时候，自然不能类比出下面的结论。c是无关选项

我也选的这题 ，和你选的一样是C，作者观点主要表明无糖食品并不能减少人均脂肪耗这一事实。作者对地manufacture 的claim的 the same texture and taste 态度表现为： 作者的even if否定这一假设，那么选项B应该符合作者的观点，也就无法否定作者的argument了，
我也没弄明白。
