Answer:
The definition of the word foul:
1. This can be used to describe a play that doesn't count in a sports game.
2. This can be used to describe something very disgusting or gross.
In both a powerful discourse and an influential paper you are trying to convince your gathering of people to agree with your disagreement. One difference would clearly be that in one your are writing and in the other you are talking which implies you may have an alternate gathering of people between the two. Another disagreement would be that when writing a paper you can incorporate more weakness and describe while the conversation includes more visual models.
Hope you understand
