Answer: Regulating big business

Explanation:

I took the test and this was the answer

The correct answer is A) regulating big business.

A common campaign promise for both the progressive and democratic parties was "regulating big business."

Both, progressive and democratic parties believed that they had to regulate business to prevent the formation of monopolies.

One to do that was by legislation and price controls. Without government regulation, cases such as the Standard Oil Company of John Rockefeller or the Steel company of Andrew Carnegie would be permanent in the United States.
