Answer: While I am unsure as to who the 'His' in the question is, I can in fact tell you that Coerce means, to force someone/something to do something by using force. I can assume that the person the question is referring to's mind is being coerced because of a refusal of doing something. I'm hoping this helped you out a little! however i'm sorry i couldn't help you out more with the second part of the question! if you have any other questions I can certainly try to help you <3
