Final answer:
An argument is a claim on paper that must be supported by evidence and reasoning.
Step-by-step explanation:
An argument is a claim on paper; every claim you make must be supported by evidence, reasoning or other information.
In academic writing, an argument is usually a main idea, often called a "claim" or "thesis statement," backed up with evidence that supports the idea.
A claim is a statement that something is true or valid, or that some action should be taken. Every claim in an argument should be supported by logical reasoning and evidence such as facts, statistics, anecdotes, examples, or quotations.
