Step-by-step explanation:
The question is asking how the author supports the thesis with reasoning and whether it is sufficiently supported. To answer this question, you should analyze the speech and identify examples of the author providing reasoning and evidence to support the thesis statement. You can quote or paraphrase these lines from the speech as evidence of the author's support. The more scholarly the source, the better, so it's important to use authoritative primary or secondary sources for evidence.
