Which statement best supports Eads being considered the first great American engineer?

The statement that Eads tackled important tasks satisfactorily best supports the idea of him being considered the first great American engineer because it highlights his ability to address significant engineering challenges of his time. Eads is renowned for his contributions to large-scale projects, including the construction of the Eads Bridge over the Mississippi River, which demonstrated innovative design and engineering techniques. His successful completion of these major undertakings not only showcased his skill but also helped to elevate the field of engineering in America, establishing a reputation for excellence and setting a standard for future engineers.

In contrast, having many assistants would not inherently demonstrate his abilities as an engineer, and working primarily on small projects would not reflect the impact or scale of his contributions. Inventing new materials, while an important aspect of engineering innovation, does not specifically highlight Eads' achievements in tackling significant engineering tasks. Thus, focusing on his successful handling of important projects provides a clearer rationale for recognizing him as a pioneering figure in American engineering.
