Question

a strong outline for an argumentative essay should include
educated opinions to provide the argument.
evidence to support a claim.
only the introduction and conclusion

Explanation:

An argumentative essay outline needs to structure support for a claim. Evidence is critical to validate the argument, while educated opinions are not substitutes for structured support, partial sections (only intro/conclusion) are incomplete, and excessive details are unnecessary for an outline.

Answer:
