My name's Sara and I'm going into my first year of AP History (I'm scared out of my mind). We were given a summer DBQ, and I have no clue how to write one or how to start off. Any help would be appreciated.

Here's the question:
"To what extent was America's massive Industrial Period (1865-1900) caused by the economics of capitalism, with particular emphasis on entrepreneurial leadership and innovation; or more the result of a very strong connection between business and the federal government, which served to strengthen the hands of the industrialists at the expense of workers and unions."

Thanks!
