at the end of the section called "the rough rider thunders out", what does the book say are the three major contributions of roosevelt that lasted beyond his presidency?

The book states that the three major contributions of Roosevelt that lasted beyond his presidency were: the construction of the Panama Canal, the expansion of national parks and forests, and the regulation of monopolistic corporate trusts.

In order to provide a step-by-step answer, I would need the specific name of the book or the author you are referring to. Could you please provide those details?
