Question

which is the main persuasive appeal used in this ad? proven to last longer leading brand supersponge lasts 2x longer than the leading brand ethos (character) logos (reason) pathos (emotion)

Explanation:

The ad uses "Proven to last longer" and "Lasts 2x longer than the leading brand" with a bar - graph - like visual. Logos is an appeal to reason. The ad presents factual - sounding information (longevity claim) and a visual that implies a comparison (bar - like elements) which are based on logic and reason. Ethos would be about credibility (e.g., expert endorsement), and pathos is about emotions (e.g., making you feel good/sad). Here, the focus is on a rational claim (longer - lasting).

Answer:

logos (reason)
