17.   Every painting hanging in the Hoular Gallery is by a French painter. No painting in the Hoular Gallery is by a Vorticist. Only Vorticists use acrylic monochromes in their works.

If the information above is true, which of the following must also be true?

(A) No French painters are Vorticists.

(B) All Vorticists use acrylic monochromes in their works.

(C) Some French painters do not use acrylic monochromes in their works.

(D) No French painters use acrylic monochromes in their works.（C）

(E) All French painters who use acrylics use acrylic monochromes in their works.

答案是C。但是我觉得B好像也对阿，Only Vorticists use acrylic monochromes in their works.不就是 All Vorticists use acrylic monochromes in their works吗？请指教，多谢！

 Only Vorticists use acrylic monochromes in their works.不就是 All

Vorticists use acrylic monochromes in their works吗？

完全不相等阿！比如：只有小学生带红领巾和所有小学生带红领巾，范围不一样啊。只有小学生带红领巾，只能说明带红领巾一定是小学生，可能也存在小学生不带红领巾的情况。

楼主再想想

我发现这样的题画个图好像比较快

一个法国画家画了HG里面挂着的所有的画

只有V会试用化学物质，HG里面没有V画的画

至少能说明，说明一个或者一些法国人不涌化学物质
