Answer :
The persuasive technique being used in the advertisement analyzed by Corey, where the majority of the population is shown using a specific brand of sunscreen, is the "bandwagon" technique.
Explanation:
1. Bandwagon technique: This technique aims to persuade people to do or believe something because everyone else is doing it. In this case, the advertisement suggests that since the majority of the population uses this specific brand of sunscreen, others should join in to be part of the group or trend.
2. Example: The advertisement could show images or testimonials of numerous people using the sunscreen, creating a sense of belonging and influencing individuals to follow the crowd to feel included or accepted.
By understanding the bandwagon technique, Corey can recognize how the advertisement appeals to the desire to be part of a popular or widely accepted choice.
