How?!
## Notes
1. > 7 bits, (probably) *because* the first one determines the charge.
2. What?
1. I've watched Craig and Dave, now, so I realise I need to leave the extraneous 0s and first 1 unflipped:

1. [x] Correct:
The left-most non-overflow unit should be 1⁄1, because, as the previous answer demonstrates, the sum of "1 + 1 with a carried 1 from a previous 0 + 1" is 1. That is because it's otherwise 0, so it can be replaced by 1.
Consequently, the correct answer is:
