我觉得有上说的有问题： "Gourmet cooks, fast-food cooks, and cooks who are health food enthusiasts 并不等于全部的good cooks" Other good cooks are health food enthusiasts 这个是不是表示前三者已经是所有的good cooks了呢？ But even though not all good cooks are big eaters 那这里应该就是指所有的good cooks了。
我觉得E的错误在于没有good，变成了泛指的cooks，造成了讨论对象和原文不一致。 |
