Slaves in the south worked in all of the following except: a. banks c. iron works b. tobacco factories d. laundries

a. banks

Explanation:

The slaves in the South were put to work in places where the majority of the population either didn't wanted to work, or where there was a lack of labor force. Whichever the way, the slaves were only allowed to work manual labor, usually the hardest one, so they were mostly included in the agriculture, and some in the iron works, or laundries. The banks were definitely not a place where they were allowed to work, and even if they were, they would have not been able to because they were not educated for such a work.

united states reinforcements contributed greatly to three allied victories in france at: cantigny (first major american battle), argonne (the largest in the united states military history, involving 1.2 million american soldiers), and château-thierry (one of the first actions under general pershing).
