Question

which is the main persuasive appeal used in this ad? solowin: the new science of skin care skin rich in hyaluronic acid skin low in hyaluronic acid ethos (character) logos (reason) pathos (emotion)

Explanation:

The ad uses visual representations (diagrams of skin with and without hyaluronic acid) and the term "science" to appeal to logic. Logos is about using reason, facts, and evidence. Here, the scientific - sounding term and the visual comparison (which implies a logical cause - effect relationship: hyaluronic acid levels affect skin structure) are elements of logos. Ethos would be about credibility (e.g., a dermatologist endorsing), and pathos would be about emotions (e.g., fear of aging skin).

Answer:

logos (reason)
