A is maybe the more difficult for analysis B is probably the most difficult to analyze C is probably the most difficult for analysis D is probably the more difficult to analyze E is , it maybe the analysis that is most difficult 该题答案不难确定是B（根据最高级和difficult的用法） 但不明白的是 og中关于maybe和probably只提到这里必须用probably取代maybe，没有做任何解释 我不明白两者有什么区别，为什么该题中用maybe就是错呢？ 有人帮忙解释一下吗？万分感谢！ |
