Are my answers right

1)whose

Yes, your answers are correct:

1) "who's" is the correct choice because it is a contraction of "who is" and is used to ask about the ownership of the car.

2) "it's" is the correct choice because it is a contraction of "it is" and is used to clarify that the car belongs to Fred.

3) "no" is the correct choice because it is used to negate the statement that Al's car is red and suggests that it might actually belong to the Jones family.

4) "their" is the correct choice because it indicates ownership by multiple people. "here" is the correct choice because it refers to the arrival of Bob and Tony.

5) "new" is the correct choice because it describes Tony's car as something recently acquired. "great" is the correct choice because it suggests that Tony's car is excellent.

6) "your" is the correct choice because it indicates possession by Al.

7) "accept" is the correct choice because it means to agree to forgive someone's mistake.
