Question

Which statement is the best thesis for a compare-and-contrast essay?
Both billboards use slogans and graphic images to urge citizens to participate in county-sponsored recycling programs.
Both billboards use effective slogans, but the one with the photograph of the overflowing landfill is the most convincing.
One billboard has a photograph of the county landfill, while the other depicts a cartoon family recycling their cans at the curb.
One billboard’s slogan is “Rethink,” while the other suggests “You Can Do This!”

Answer 1

The second statement: "Both billboards use effective slogans, but the one with the photograph of the overflowing landfill is the most convincing."

Why: It’s specific, comparative, and arguable — it identifies a shared feature (slogans) and makes a clear claim about which is more effective, giving you a stance to support and organize the essay around.
