The game _____ 2hours. At last,our team won the game.
A lasted B kept on 这2个有什么区别？

Is this factory__ you visited the other day ?
Awhich B that C the one D where为什么

The game _____ 2hours. At last,our team won the game.
A lasted B kept on

A
A表示持续，B是“继续, 穿着...不脱”，一般用人作主语。

Is this factory__ you visited the other day ?
Awhich B that C the one D where

C
你可以从陈述句的角度来理解：
This is the factory that you visited the other day.
This factory is the one (that） you visited the other day.
这句话对应的陈述句是第二种，注意它与第一种的区别（第一种有先行词，第二种没有，要补出the one）。所以是选C。
