[an] argument is a claim or series of claims supported by evidence through reasoning
reasoning refers to the ability to make an inference or a judgment based on evidence (Gunn 2017, loc. 463)
Rebuttals critique the others’ reasoning and evidence underlying their claim.
You often rebut by: (1) restating claim, (2) expressing disagreement, (3) critique reasoning/evidence, and (4) conclude.
