This math problem is so difficult that only ( ) students can work it out A.a few B.few
我选了b 可是书后答案却选a为什么？？

Answer 1

有 only 时填 a few ，表示肯定，虽然难，但还是有人能回答这个问题。
如果没有 only ，则填 few 表否定， 问题太难以至于没人能解决。

Answer 2

答案也是有错的时候啊
再或者是因为原句用的so而没有用too所以选a few
但是我认为选few确实更好一点

Answer 3

only a few这是固定用法啊

Answer 4

我也选的B，答案是A
