必须有bones,排除ABE(否则就近修饰)
known to be 表示acknowledged as,而known as 表示named,所以排除BDE 剩下AC,因为bones不可能to be animals,故排除A
known as = named 被称为,亦称为 known to be = acknowledged as 作为...被熟知,众所周知的是... known for 因为...而出名 known by 凭...而出名 搭配: known as + n known to be + adj/n
known as的话出现修饰错误, 这个known as 是在说什么东西? 前面的caves?还是 europe? 后面的 those of the remains of 也出现了复杂的修饰结构,基本可以定义为修饰不清
没有bones. assumed to be those(bones) of the remains of重复
