Answer:
A. The use of strong emotional appeals to persuade the audience.
Explanation:
Using process of elimination, we can get rid of all the other options.
- B) is wrong because the speaker is in no way being optimistic, especially about college.
- C) is wrong because there isn't repetition of the words 'students' and 'education'.
- And D) is wrong because that simply is not the strongest part of the argument.
Ultimately, we can narrow it down to (A) and (D). (A) is simply more true, and is the better answer, as the statistic about the average student debt of a college student is more powerful than the credentials.
