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
答案里面除了D是绝对不可能的，其他四个都有可能。因为D中 enjoy serving and preparing food 的 good cook 是 good cook 的全部，而 big eater 的 good cook 只是 good cook 的一部分，所以前者绝不会比后者少。而E中，没提good cook，所以 Gourmet cooks, fast-food cooks, and cooks who are health food enthusiasts 中有一部分是 good cook，有一部分可以不是，它们与 big eater 的任何数量关系都有可能发生。
