Question

This is the problem of modern sociology-to discover the degree to which hard-wired genetic programming dictates,or at least strongly biases,the interaction of animals and human with their environment,that is,their behavior.请问'''这路的degree to which 该如何理解?这后面是定语从句吗?如果是'''可以替换成哪个连系副词?后面两个逗号间的that 为什么要用逗号隔开''''感谢解答!

Answer 1

degree to which 是which 引导的定语从句,表示多大程度上.不能用关系副词来代替.
that is 是插入语,意思为 即是,更确切地说.,用来解释“the interaction of animals and human with their environment”
