The only counterforce that was potentially strong enough to control the business trusts of the late nineteenth and early twentieth centuries was:: select one:
a. government.
b. the buying public.
c. organized labor.
d. business competitors.
e. farmers.
I'd say government, as many people wanted government action, and in the early twentieth century that's what they got with Teddy Roosevelt as president, and even before that when he was governor. Hope that helps!
