What feeling does the passage evoke regarding J.B. Eads' achievements?

The choice that captures the feeling evoked by the passage regarding J.B. Eads' achievements is rooted in a sense of incredulity about how his contributions are perceived over time. His innovations, such as the design of the Eads Bridge, may not have received the level of acknowledgment they deserve, which can lead to a questioning of the legitimacy of the accolades he has attained. This perspective suggests that there is an underlying sentiment of skepticism regarding how widely recognized or celebrated his contributions truly are, despite their impact on engineering and infrastructure.

In contrast, the feelings of admiration, frustration, or surprise are not aligned with the primary sentiment conveyed. While people may indeed admire his work or feel frustrated that it is not well recognized, the focus here is on the doubts surrounding the validity of the fame he holds. This points to a deeper analysis of how historical figures like Eads are remembered, rather than merely celebrating or lamenting their achievements.
