During a speech on the need to limit growth at State University, Leeland states, "According to Mary Sue Kaye, Dean of Students, if State U. does not cap enrollment soon it will be impossible to offer enough classes for students in most majors to graduate in four years." What for of supporting material is he using?

Testimony.

Explanation:

Testimony is defined as 'an account of first-hand experience or a solemn affirmation by a witness' which can be the best evidence or proof to substantiate a claim.

In the given speech, the statement made by Leeland exemplifies a 'testimony' which he employs to support his claim i.e. 'need to limit growth at State University.' It would be considered a testimony as it states a 'first-hand experience of a witness('Mary Sue Kaye, Dean of students') who states that there is a lack of availability of enough classes to be offered to students in most majors.' Since it is a first-hand experience by Dean herself, it can be rely upon easily, and therefore, it not only supports the speaker's point but also persuades the audience to believe it.

to me i think class room sitting education is better. i do online school and i have not learned a think haha. when i sit in the classroom i just sit there and kind of pay attention but still i get so far ahead in the class when im doing online i have nothing else better to do but play video games and i sit in school and learn and have friends and just actually learn. when i'm doing online i sit here listing to music and get on and and look up the answers i guess that is my fault for being a cheater. but to be honest i think sitting in the classroom is better.
