Intonation in the given sentences?

Please check if my answer is correct or not. I am little doubtful about my answer in no. 7. Please give your feedback. Thanks.

Ques: Decide whether the intonation is rising or falling at the end of given sentences and give reason to support your answer:

1. Who is he? Falling intonation / Wh-question

2. Is she here? Rising intonation / Yes/No or polarity type Question

3. You´re going aren´t you? Rising intonation / Tag-question

4. You aren´t going are you? Rising intonation / Tag-question

5. Why did you do it? Falling intonation / Wh-question

6. That´s so nice of you! Falling intonation / Exclamations

7. Tim said that? Rising intonation / Repetition-question or confirming

 They're all fine (even #7).

it is easy if you know the different kind of intonations because it is the very impotant part of an intonation.
