SECTION B-14再讨论

14.   The Western world’s love affair with chocolate is well-documented: few people have been known to have tasted it for the first time without requesting more.

(  A) few people have been known to have tasted it

(D) few people have been known to taste it（D）

A项为何错误呢？按照the first time的提示，以及taste和know的先后关系，应该选A才对吧？

以前的帖子中没有作出明确的解答，还请高手指点。

我也疑问中，NN帮解释一下吧。
