Advertising

Need help with these questions.

1-How is advertising used to persuade the public? How have you been influenced to purchase a product or service by an advertising campaign? What type of media was used? Why was the advertisement effective?

2-What do you consider the four most important guidelines when preparing a presentation? Based on the criteria, was your last presentation effective? Considering your content; organization; physical, verbal, nonverbal, and vocal delivery; and multimedia, what did you do well in the presentation? What could you have done to improve it?
