Answer:
A claim of fact makes an assertion about something that can be proved or disproved with factual evidence. However, keep in mind the basic quality of claims, that they have to be debatable, and offer an assertion about an issue. So a claim of fact for a logical argument cannot simply consist of a statistic or proven fact. It needs, instead, to focus on an assertion which uses facts to back it up, but for which the evidence might still be debatable.
Inappropriate claim of fact – a statistic or fact that is not debatable:
