Explanation:
Advertisements are meant to create a positive impact in the minds of the people who view them. It is actually meant to provide more information about the product and the features that will benefit potential customers. It is thus important to use the right words, which wouldn’t have any negative words involved in it.
I feel the use of the word'' folly'' is not a good one, it's not sending the right messages to people, and it's not also achieving its main purpose.
