Questions: What noun is the appositive renaming in the following sentence? My brother, Peter, crashed his brand new bike.

The answer is "brother."

Explanation: An appositive is a noun or noun phrase that renames another noun right beside it. In the sentence "My brother, Peter, crashed his brand new bike," the appositive "Peter" renames the noun "brother."

• "brother" is the noun being renamed by the appositive "Peter."
• "crashed" is a verb and not a noun, so it cannot be renamed by an appositive.
• "bike" is another noun in the sentence, but it is not being renamed by the appositive "Peter."

Therefore, the correct answer is "brother."
