· Oprah Winfrey is a credible source for many reasons. She is a trustworthy source and she has been for many years. On her show she talked about some things that people didn’t even know about; she once told the story of a man who was born as a boy but raised as a girl. She been on TV for as long as I can remember.

· Current President Biden and former President Trump are not credible sources especially when it comes to Covid-19. Neither of them are doctors. Neither of them have done any kind of research themselves. A lot of the things they say, they only say to make themselves look good.

· Yes, I did find the attractive source effective. I found it effective because I am a big fan of Bad Bunny and if I see he is on an ad for something or he is promoting something, I want it. I want it just it’s associated with him. I think when a famous person is attached with something their fans will go do almost anything they say.
