which rhetorical appeal is primarily used in this ad?\ncertified heart healthy by the american heart…

Brief Explanations:

Ethos is an appeal to credibility or character. Here, the ad mentions "Certified heart healthy by the American Heart Association." The American Heart Association is a respected and authoritative organization in the health - related field. By associating the soup with this organization, the ad is trying to build trust and credibility with the audience. It is leveraging the good character and reputation of the American Heart Association to make the claim that the soup is healthy more believable. Logos would involve facts, statistics, or logical reasoning (e.g., "this soup has X grams of protein which is Y% of your daily value"). Pathos would appeal to emotions (e.g., "this soup will make you feel warm and loved like grandma's cooking"). Since the ad is using an authoritative source (the American Heart Association) to establish credibility, it is using ethos.
