The correct answer to this open question is the following.
Although there are no options attached we can say the following.
One major problem that resulted from industrialization was the creation of monopolies, which controlled all the prices in one sector of the economy and absorbed their competitors.
To help solve this problem, Congress created legislation to end monopolies and promote free enterprise and free competence.
During the so-called Gilded Age, rich people owned powerful companies that created monopolies. This was the case of the Standard Oil Company owned by Jhon D. Rockefeller or the US Steel Company owned by Andrew Carnegie. We can also name the American Tobacco Company owned by J.B. Duke.
That is why, during the Progressive Era, the government created new legislation to dissolve monopolies and prevent the creation of new ones. The purpose of this new legislation was to promote free enterprise and free competence.
