What is the author’s primary argument in the passage?

The writer begins the passage by remarking that most Americans today don’t even know who Thomas Paine is, and then goes on to discuss all of the reasons he should be remembered. Answer choices (C) and (D) are not supported by the passage, and while the writer does posit that Thomas Paine made important contributions to the American Revolution, he doesn’t go so far as to imply that it never would have happened without Paine.
