What strategy could strengthen Feldstein's argument regarding the walking trail's benefits?

Citing successful similar projects effectively strengthens Feldstein's argument by providing concrete examples of the benefits realized in comparable situations. This approach can enhance the credibility of the argument, as it draws on empirical evidence and demonstrates that similar walking trails have positively impacted communities. By sharing these successful case studies, Feldstein can illustrate potential benefits such as increased foot traffic, enhanced community engagement, and positive economic impacts, making the case for the proposed walking trail more compelling and relatable to the audience.

This strategy also addresses potential skepticism by showing that the proposed benefits are grounded in reality rather than just theoretical outcomes. Showing real-world success stories can persuade stakeholders that investing in the walking trail is a viable and worthwhile initiative, thus bolstering the argument further.
