How does Schlosser's anecdote about Elisa contribute to his argument?

The correct answer focuses on how Schlosser's anecdote about Elisa serves to evoke empathy from the reader by illustrating her daily struggles. By sharing a personal story that highlights the challenges faced by a fast-food worker, Schlosser provides a human face to the issues within the industry. This narrative allows readers to connect emotionally with the experiences of individuals like Elisa, thus deepening their understanding of the broader implications of fast-food labor practices. The emphasis on personal struggles helps convey the real-life impact of the industry's labor conditions, making the argument more relatable and compelling.

Other options, while they may touch upon different aspects of the text, do not adequately capture the emotional resonance that Schlosser achieves through Elisa's story. For instance, while the authority of the author might be established elsewhere, it is not the primary focus of this anecdote. Similarly, the anecdote does not primarily deal with statistical facts or discussions about the age factor; it is more centered on personal experience and the hardships faced by workers. Thus, the emotional connection is what makes this element of Schlosser's writing particularly powerful in supporting his argument.
