What are the subordinate clause in these sentences?

1. Brett, who is a football star, is class president.
2. Bonnie, who is an artist, is also studying computer science.
3. The composer who wrote music comes form Germany.
4. My address book, which is bright red, is gone.
5. Ann, who is from Georgia, just started working here today.

If you can drop it out and the remaining sentence still is reasonable, it is subordinate.

eg:

Brett is class president.
Bonnie is also studying computer science.

Ann just started working here today

To identify the subordinate clauses in these sentences, we need to understand what a subordinate clause is.

A subordinate clause is a group of words that includes a subject and a verb but cannot stand alone as a complete sentence. It typically functions as a dependent clause, providing additional information or expressing a relationship to the main clause in the sentence.

Let's analyze each sentence to identify the subordinate clauses:

1. Brett, who is a football star, is a class president.
- The subordinate clause here is "who is a football star." It provides additional information about Brett.

2. Bonnie, who is an artist, is also studying computer science.
- The subordinate clause is "who is an artist." It provides extra information about Bonnie.

3. The composer who wrote music comes from Germany.
- The subordinate clause is "who wrote music." It provides additional information about the composer.

4. My address book, which is bright red, is gone.
- The subordinate clause is "which is bright red." It provides extra information about the address book.

5. Ann, who is from Georgia, just started working here today.
- The subordinate clause is "who is from Georgia." It provides additional information about Ann.

By identifying the clauses in each sentence and understanding their functions, we can determine the subordinate clauses in these sentences.
