救助 prep 题

The loan company announced it would soon lend money to borrowers with proven records of their not paying back their loan on time, collectively known as the subprime lending market.

A of their not paying back their loans on times

B of not paying back their loans on time, a group

C of not paying back their loans on time, with such a group

D that they do not pay back their loans on times, such a group

E that they do not pay back their loans on times

答案： B

真是太笨了我  我的问题是 A GROUP 在选项B 中是什么成分啊？  为什么A 不对啊

a group是同位语，补充修饰前面说的borrowers

A their多余 record of doing 固定用法， on time 按时 也是固定用法，没有 A group做先行 known 有修饰records 的歧义
