the study of the wild world may help to make the world easier______.

A.understand B.to be understand C.to understand D.understood

我想问下选哪个,解释得越详细越好,谢谢!!

C
当遇到 easy,hard,difficult,comfortable这些形容词的时候,用主动表示被动。例如:
This book is difficult to understand.
the house is comfortable to live in .

如果把easier 改成:more easily 就选D

选这个D.understood
make sth. done固定搭配

都错了,应该是
to be understood
