Question

president taft’s passage of the mann-elkins act in 1910 continued roosevelt’s legacy of railroad reform by
strengthening the interstate commerce commission.
establishing the interstate commerce commission.
continuing to lower railroad rates.
reestablishing the practice of giving rebates to large companies.

Explanation:

To solve this, we analyze each option:

• The Interstate Commerce Commission (ICC) was established in 1887, not by the Mann - Elkins Act in 1910, so the "establishing" option is incorrect.
• The Mann - Elkins Act of 1910 was about strengthening the ICC, giving it more power over railroads (like regulating telephone and telegraph companies too), not primarily about lowering rates or reestablishing rebates (rebates were part of the problems the ICC was meant to stop). So the correct option is the one about strengthening the ICC.

Answer:

A. strengthening the Interstate Commerce Commission.
