What is the relative or nonrelative clause in each of the following sentences? Because you cant highlight put a * on either side of the clause in each sentence then state after each sentence if it is relative or nonrelative

A example of how to do it is :

The man *who called you* is my dentist. (relative)

1. The umbrella that I bought last week is already broken.
2. The man who stole my backpack has been caught.
3. Greg, who hates mushrooms, ate the whole pizza himself.
4. The weather we had yesterday was dreary.
5. London, which is the capital of England, is one of the largest cities in the world.
6. The ice cream which melted on the porch was completely wasted.
