Question

my friend and i went skiing, which was freezing, and then we enjoyed the cocoa that warmed us. independent nonrestrictive restrictive

Explanation:

1. The clause "which was freezing" adds extra, non-essential detail about the skiing experience and is set off by commas, so it is nonrestrictive.
2. The clause "that warmed us" is essential to specify which cocoa is being referred to (it limits the noun "cocoa" to the one that had the warming effect) and has no commas, so it is restrictive.
3. The main clauses "My friend and I went skiing" and "then we enjoyed the cocoa" can stand alone as complete sentences, so they are independent.

Answer:

• "My friend and I went skiing" / "then we enjoyed the cocoa": independent
• "which was freezing": nonrestrictive
• "that warmed us": restrictive
