• Many people in town do grocery shopping after they come home late.
This sentence replaces the underlined sentence to improve the effectiveness of the argument because it provides evidence to support the argument that the grocery store should be open after 8:00 p.m. Instead of simply dismissing Mr. Rodriquez's argument, the speaker provides evidence to show why their own argument is more valid. By acknowledging that many people in town need to do grocery shopping after they come home late, the speaker provides a practical reason for why the grocery store should be open at those hours.
