since一般与现在完成时进行搭配，这里与过去完成时搭，错；releasing分词的主语应为主句的主语，即their descendants，但实际主语为honeybees，所以错

since+现在完成时；releasing的主语是descendants 不符合逻辑

since 与现在完成时搭配 不与 had migrated 搭配； since releasing 是分词结构句子的逻辑主语应是主句主语 their descendants killer bees 而这里是honeybee 。

(B) since releasing放在句首,逻辑主语等于句子的主语their descendants, 不符合逻辑; since是现 在完成时的标志和had migrated矛盾; since的使用不符合习惯用法 补充说明:since的四种用法:since +过去一个时间点(如具体的年、月、日期、钟点、1980, last month, half past six)。 I have been here since 1989.since +一段时间+ ago I have been here since five months ago.since +从句 Great changes have taken place since you left. Considerable time has elapsed since we have been here. It is +一段时间+ since从句 It is two years since I became a postgraduate student.

如果是releasing，那么逻辑主语是后代，和原句句意不相符

releasing主语为主句主语descendants，但不符合逻辑

分词短语在句首起状语作用,逻辑主语等于句子主语 descendants不是release的主语
