Step-by-step explanation:
An example of a logos appeal in 'A Fable for Tomorrow' would involve the use of clear, rational arguments backed by credible evidence to support a position. When an author effectively employs a logos appeal, they provide facts and statistics to underpin their arguments, demonstrating sound reasoning to sway their audience.
