After Concert

After the concert , we took our "Dinner" at HB1. After few minutes , my friend Jerry came and bought beverage. While he was waiting for his drink , he came and talked to us. And I found some vague sentences in his speech.

Jerry: Do you know that there are people who are very good in giving her speech in DJ Club? Her name is XXXX. A company even put their advertisements during her slot!How amazing is she?

Jason: Wow, even though I'm active in DJ club but I never heard of her. I think there are 2 reasons why they put their advertisements on her slot. First, the company maybe established by her father . Second, she is a profession in this kind of stuff.

Jerry: Well , I think that she is very good in speaking because she is fluent in talking and because of fluency in talking so she is very good in speaking.

From above we can conclude that Jerry is using material fallacy or more details is he used the Circular Argument .This is because the conclusion essentially appears both at the beginning and the end of the argument, it creates an endless circle.
