Hey There!
The situation that is considered reinforcement is Receiving a "thank you" from somebody after doing something nice.
Thank You!
I believe the answer is Acting as conduits for gods
Andrew jackson describe the election of 1824 as a corrupt bargain because he thought south carolina voted for John Quincy adams in order to make it easier to Secede.
Back then, John Quincy simply doesn't have enough vote to be considered as the winning candidate, making the credibility of the election really questionable
hope this helps
