When used to sweeten food , blends greatly decrease the likelihood that consumers will exceed acceptable daily intakes for individual sweeteners . Blends should therfore be used , rather than single sweeteners alone ,since blends are clearly more healthy ,yet equally effective.
问题 The argument above depends on which of the following assumptions? A When ingested together ,different artificial sweeteners in the blends do not interact in a way that makes them harmful to human heakth. BThe ill effects on health produced by the intake of excessive quantities of any single artificial sweetener cannot be reversed by reducing intake later.
这道题 ，我感觉A 和B 都可以~~ B 通过 对一种人工增添剂危害的对比来 加强了文章的结论：说blends 应该被使用~作者: wildbean 时间: 2011-11-10 15:29
文中提到因为食用混合甜味剂更有好处，所以应该被采用 B The ill effects on health produced by the intake of excessive quantities of any single artificial sweetener cannot be reversed by reducing intake later. 只是说到了食用单个甜味剂不好的地方，并没有提及到混合甜味剂的任何方面，所以对文中结论的导出没有加强作用
