英文问题求解。请问下面这句话，where引导的是定语从句吗?

In 2004, there was a programme in Britain where contestants were not allowed to sleep for seven days to try to win 97,000 prize money.

where 指代 in the programme (在活动安排中)，它引导的从句相当于 contestants were not allowed to sleep for seven days (in the programme) to try to win 97,000 prize money。所以，这是 where 引导的定语从句。

你好， where引导的定语从句，因为where是关系副词，所以where在从句中往往作地点状语。 this is the place where we lived before.这就是我们以前居住过的地方。
