Final answer:
To answer how an author supports their thesis with reasoning, one must provide specific references from the speech, including explanations, clarifications, and concrete evidence, that showcase the author's argumentative support.
Step-by-step explanation:
The question inquires about how the author of a speech supports their thesis with reasoning and whether it is considered sufficiently supported. To justify an answer to this, one would need to select specific lines from the speech that illustrate the author's reasoning and evidence towards their thesis.
The effectiveness of this support is measured by the explanation, elaboration, and clarification given, as well as the concrete evidence presented to reinforce the author's main points. When drafting a response to this question, it's critical to introduce and explain a major point that backs the topic sentence, ensuring that there is adequate information to both explain that point and link it back to the overall thesis.
One should present evidence in the form of quotes or paraphrasing from authoritative sources to support both the paragraph's and the thesis's main idea. In doing so, the response demonstrates an understanding of effective writing structure and an ability to engage critically with the material at hand.
