狒狒一题,求教!

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.

我怎么觉得B也象答案啊?

B 从结论可以退出： not all good cooks are big eaters, they all enjoy preparing and serving food. 不是所有的好的厨子都是big eaters，但是他们都爱preparing and serving food。就是说所有好的cooks里面有些是big eaters 有些不是，但是这些good cooks all enjoy preparing and serving food

open to discuss。。。
