The correct answer is "The government played a greater role in regulating the economy and society."
The Progressive era in American history saw several different Progressive presidents including Teddy Roosevelt, William Howard Taft, and Woodrow Wilson. All of these men used the government as a way to have greater control over the economy.
For example, Teddy Roosevelt filed several lawsuits against businesses/individuals who acted like trusts. Roosevelt felt that these trusts created a type of monopoly that limited competition among businesses in the US.

The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
Considering the Civil war in the context of the Industrial Revolution, the impact of factory production was huge in a couple of industries.
We are talking about the weapon industry and the steel industry. Indeed, both industries bloomed during and after the American Civil War.
The weaponry industry increased its production of weapons used on the battlefield by the Union Army and the Confederate army. To produce those weapons, the industry needed steel: guns, rifles, cannons, ships, and more.
Agriculture in that time also increased and the other industry that flourished was the transportation industry, particularly, railroads, those transported goods, weapons, and people across the territory during the war.
If those are your options the answer is B.
Hope this helps! Have great day.
