Final answer:
The excerpt aids the authors in drawing a conclusion by presenting facts, providing statistical evidence, or using deductive reasoning. The use of rhetorical devices like repetition can also emphasize the points made. An analysis at the end of a paragraph connects the evidence back to the topic sentence.
Step-by-step explanation:
The excerpt would help the authors arrive at their conclusion by presenting facts, providing statistical evidence, or using deductive reasoning. Presenting facts about a topic, such as the bagel business, can establish a strong foundation and credibility for the author's claim. Providing statistical evidence involves sharing data that support the claim, which can be a powerful tool to convince the readers of the argument's validity. Using deductive reasoning allows the author to draw logical conclusions based on premises that are presumed to be true; this form of logic relies on the structure of arguments to guarantee the truth of the conclusion, as long as the premises are true.
Rhetorical devices like repetition, and rhetorical questions are also used to emphasize the points and help to unify the text. Supporting claims with convincing evidence is crucial and can be achieved through different methods such as quoting, summarizing, or paraphrasing expert opinions; relating anecdotes and examples; and citing appropriate statistics and facts. The analysis of the evidence is typically done at the end of a paragraph, where the author draws a conclusion in their own words, connecting the evidence back to the topic sentence.
