The disappearance of dinosaurs made___ the rise of mammals which gave birth to young baby animals.
问题描述：
The disappearance of dinosaurs made___ the rise of mammals which gave birth to young baby animals.
A.it was possible B.it possible C.possible to be D.possible
答
句型：make something possible使某事成为可能
其中的something=the rise of mammals which gave birth to young baby animals 分娩小动物的哺乳动物的崛起
"which gave birth to young baby animals"是用来具体解释说明mammals
当make something possible句型中的something是复合结构或者很长很复杂的时候,句型一般会转换为make possible+something
整句主语：the disappearance of dinosaurs 恐龙的灭绝
谓语动词组：made...possible
翻译：恐龙的灭绝使分娩后代的哺乳动物的崛起成为可能.
