Without the specific passage to analyze, I can't determine the type of argument the author uses in their speech. However, I can explain the terms:
- Logos refers to the use of logic, facts, and evidence.
- Pathos appeals to the audience's emotions.
- Ad hominem is an attack on the person rather than the argument.
- Syntax relates to the structure of sentences.
If the speech primarily relies on logic and reasoning, it would be logos. If it aims to evoke emotional responses, then it would be pathos. An argument that attacks the opponent rather than addressing the argument itself would be ad hominem.
Please provide the passage or additional context for a more accurate answer.
