Which example in the text best demonstrates the author’s use of factual evidence?

The choice that demonstrates the author's use of factual evidence is centered around the statement that many restaurant workers speak no English at all. This assertion relies on concrete data that highlights a significant aspect of the fast-food industry, particularly with regard to the workforce's demographics and linguistic diversity. By presenting this information, the author underscores the challenges and realities faced by many workers in these environments, pointing to broader themes such as immigration, communication barriers, and economic conditions that affect employment opportunities.

Additionally, this factual evidence serves as a basis for supporting the author's arguments about the working conditions and social dynamics within the fast-food industry. It provides readers with an objective understanding of the landscape in which these workers operate, emphasizing the importance of these factual elements in evaluating the industry's impact on individuals and society as a whole. The other options, while they may reflect observations or anecdotal evidence, do not provide the same level of concrete, verifiable data that can inform readers about systemic issues within the workforce.
