1. Complete with BE. Where is your mum and dad? Is your brother at school?
Explanation: In this sentence, we use the verb "BE" to describe the location or state of someone or something. We use "is" for the third-person singular subjects like "your mum and dad" and "your brother".

3. Are you from London? No, I am not.
Explanation: Again, we use the verb "BE" in the present tense. Since "you" is the second-person pronoun, we use "are" instead of "am". In a negative sentence, we use "am not" to indicate negation.
