Difference – Dispute vs. Disputation: Noun Comparison

I colored "disputation" below in gray. 1. Would it be correct to substitute it with "dispute", which is both a verb and noun?

2. In general, how does 'dispute' differ from 'disputation' AS NOUNS? I know that disputation isn't a verb.

      Coherence, clarity, and readability. Do the included facts give coherence or clarity to the story? Do they help create a readable text? Once mentioned, facts can be repeated to lead readers from one sentence or paragraph to another. For example, in Table 33, sentence 3 begins with the useful transition shortly after his reinstatement, which repeats information from sentence 2, namely that Hazelwood was reinstated. For another example, sentence 6 repeats the fact that Exxon knew the captain was an alcoholic, in the phrasing Exxon’s known alcoholic captain. Repeated information is not always problematic (see Strategy 30 and Strategy 4); it can be useful in providing transitions. However, if not useful, you should consider omitting the information.
      If you are unsure of the disputation of a certain fact, that does not necessarily affect whether or not you retain the fact. The facts you retain still need to be relevant to the law, and they need to help clarify the story or help it cohere or assist in the readability of the text. If they do not achieve these purposes, you can omit them.
