Question

they have not gained the knowledge those fairly good jobs or positions require.
这个those.在句中做什么成份.knowledge之后应该是定语从句

Answer 1

做定语,that的复数,是those最普通的用法,
它不是先行词
knowledge是先行词,这儿省略了关系代词which或that,因为关系代词在从句中做宾语
如果不省略的话：
They have not gained the knowledge that/which those fairly good jobs or positions require.
