What is a CLAIM?

A claim is a writer's position on an
issue or problem.  Although an
argument focuses on supporting one
claim, a writer may make more than
one claim in a text.
The support is the reasons and evidence that help
prove the claim.
Reasons are the statements made to
explain a belief.
Evidence is a specific reference, such
as a fact, statistic, quotation, or opinion that is used to
support a claim.
