In the early and mid-1800s, much of the north’s economy depended on a. unskilled labor supplied by immigrants. b. goods manufactured by skilled craftsmen. c. advances in agricultural technology. d. labor provided by enslaved workers.

a. Unskilled labor supplied by immigrants.

Explanation:

In the early and mid-1800s, the growth of factories in the north required a higher demand for unskilled labor, provided mostly by immigrants, primarily young males. Immigrants would usually take lower payments and poor working conditions. Higher profits allowed investments in new technology that led to a rise in production and ultimately higher salaries for workers.
