63. Some good cooks are gourmet cooks who pride themselves on always using extravagantly rich ingredients in elaborate recipes. Some good cooks can be characterized as fast-food cooks. They may use rich ingredients as long as the recipes are easy to follow and take little time. Other good cooks are health food enthusiasts, who are concerned primarily with the nutritional value of food. But even though not all good cooks are big eaters, they all enjoy preparing and serving food.

If the information in the passage is true, which one of the following CANNOT be true?

A.Most good cooks do not use extravagantly rich ingredients.
B.Everyone who enjoys preparing and serving food is a good cook.
C.More good cooks who use extravagantly rich ingredients are big eaters than are good cooks who do not use such ingredients.
D.There are fewer good cooks who enjoy serving and preparing food than there are good cooks who are big eaters.
E.Gourmet cooks, fast-food cooks, and cooks who are health food enthusiasts are all big eaters

我想问一下E选项 是怎么推出来的？
另外我看不出来原文中四句话 some ....some ....other... but...之间的关系啊，这个题目是不是挺怪的，不符合premise、conclusion啊

只需要E “可能” (Can)正确就可以排除E。（当然E不一定正确）

可不可以这么解释：原文的话说even though not all good cooks are big eaters，这里是让步，就是说，是有可能的，即前文所述的那些不同类的厨师是有可能是big eaters的，对不对？
