Question

Is an argument that does not support your thesis statement.

Answer 1

Answer:

Its True but your actual question is "A thesis statement is supported by arguments"

Answer 2

I may not have understood your question; I will assume you're trying to fill in the blank.

I suppose that blank is "an opposing argument" or something along those lines. I'm sorry if that answer was vague; consider resubmitting your question with more context for a more detailed answer if needed.
