10 multiple choice 1 point
a ______ is the underlying assumption behind an argument.
backing
ground
warrant
claim
clear my selection

Explanation:

Question 9

The statement attacks the speaker's trustworthiness by noting they falsify claims, which is questioning credibility. Validity relates to argument structure, context to situation, and data to evidence—none match here.

In argumentation theory, a warrant is the underlying assumption (or reasoning) that connects the ground (evidence) to the claim. Backing supports the warrant, ground is evidence, and claim is the assertion. So "warrant" fits as the underlying assumption.

Answer:

A. question of credibility
