I think you have some serious work to do. I disagree with 8,7, 5, 4, & 3.

I believe those are ok. I HOPE you were not confused by which of the opposite answer pairs to choose, you guessed, you guessed wrong the first time, and when I pointed them out you just chose the other one. As I say, I HOPE that isn't happening.
