Normal vs. Inverted Sentences

Finished an exercise calling for identifying whether a sentence is in normal or inverted order, and to identify the simple subject/predicate of each. I'm pretty sure I've done all these right, but I'd like some clarification before I go about handing in this assignment.

1. Ken has adjusted his goals since I last spoke with him. (NO, Ken = SS, has adjusted = SP)
2. Who has sold the most raffle tickets? (IO, tickets = SS, has sold = SP)
3. Will Celia have forgotten the clue by Monday? (IO, Celia = SS, will have forgotten = SP)
4. Nobody saw him after he left the event. (NO, Nobody = SS, saw = SP)
5. The balloons burst when the pine needles hit them. (NO, balloons = SS, burst = SP)
6. Have you visited Phoenix, Arizona? (IO, you = SS, have visited = SP)
7. Kimberly has taught in Atlanta for 25 years. (NO, Kimberly = SS, has taught = SP)
8. Would you like to sit with me during the ceremony? (IO, you = SS, would like = SP)

I'm a little unsure as to whether I've identified the correct subject in #8, so if that's wrong, please tell me, and why it is incorrect. Thank you!
