the law of demand（请求高人英语作答~~~基础问题 呵呵）
Identify the flaw in this annalysis: If more Americans go on a low -crab diet, the demand for bread will fall. The decrease in demand for bread will cause the price of bread to fall. The lower price, however, will then increase the demand. In the new equilibrumm, Americans might end up consuming more bread than they did initially. (请用英语作答,给出分析过程~~~~紧急 万分感谢）

The lower price of bread will not necessarily increase the demand of it,for its demand here is depressed not by price,but by a need of dieting,in which case,its price will not be taken into consideration.
