Tropical bats play important roles in the rain forest ecosystem, aiding in the dispersal of cashew, date, and fig seeds; pollinating banana, breadfruit, and mango trees; and indirectly help  produce tequila by pollinating agave plants.
关于这道题目 就是有一个选项 不太明白是怎么错的 烦请大家解答一下吧~~·
e) they pollinate banana, breadfruit, and mango trees, indirectly helping the producing of
请大家能不能帮忙看一下这个选项为啥错呀？？？？谢谢谢谢大家了！我是新手，还请牛牛们指点

indirectly helping the producing of 这里作状语，不当的修饰了they pollinate banana, breadfruit, and mango trees。而原句意中aiding，pollinating，helping三个应该是并列。
这题最好发语法区，那里解答的人多。
