Answer:
A. Securely
B. "...no way in the world can you get rid of the nasty hard thing..."
Explanation:
A. The word fast in this context means securely. For example, if I held my money fast it would mean that I clutched it tightly to make sure nothing could happen to it.
B. This quotation shows that the harness was held securely on the horse, since he couldn't get it off.
The answer would be vault : crash down : start : stop
The first two are opposites, so start : stop would complete the analogy
Instead of "his, " use "its"
Im not sure though
