Which term refers to a reason for favoring one side of a proposition and the facts that support that reason?

• A. Allusion
• B. Argument
• C. Antithesis
• D. Anecdote

Answer: (B)

In rhetoric and writing, the main idea here is building a case for a proposition by presenting reasons and the facts that back those reasons. This is exactly what an argument does: a claim about a proposition accompanied by supporting reasons and supporting evidence. It focuses on why you favor one side and what facts you use to justify that stance.

This fits better than the other terms because:

• An allusion is just a reference to something else, not a structured case with reasons and evidence.

• An anecdote is a brief personal story, which may illustrate a point but isn’t the formal framework of reasons and supporting data.

• Antithesis is a stylistic device that contrasts ideas in parallel form, not the act of arguing with reasons and evidence.

So the term that describes a reason for favoring one side of a proposition and the facts that support that reason is argument.
