Final answer:
Three examples of appeal to logic in Roosevelt's Four Freedoms speech are statistical evidence, reasoning, and concrete examples.
Step-by-step explanation:
Three examples of appeal to logic (logos) in Roosevelt's Four Freedoms speech can be identified through the use of statistical evidence, reasoning, and specific examples to support his arguments. Unlike emotional anecdotes, personal stories, or humor which appeal to emotion (pathos), or appeals to tradition and patriotism which can be associated with ethos, logos focuses on clear and rational thought processes to convince the audience. For instance, Roosevelt could utilize data concerning economic conditions, historical precedents, and hypothetical scenarios to illustrate the necessity of the four freedoms he discusses. The correct answer to identify three examples of appeals to logic in the speech is option b) Statistical evidence, reasoning, and examples.
