Questions: Growing demand for led to the expansion of the slave labor system in the Chesapeake. indigo tobacco sugar cotton

The answer is: tobacco.

Explanation for each option:

1. Indigo: Indigo was primarily grown in the southern colonies, particularly South Carolina and Georgia, rather than the Chesapeake region. While it did require labor, it was not the primary crop that led to the expansion of the slave labor system in the Chesapeake.

2. Tobacco: Tobacco was the main cash crop in the Chesapeake region (which includes parts of modern-day Virginia and Maryland). The high demand for tobacco in Europe led to the expansion of plantations and, consequently, the increased use of slave labor to meet the labor-intensive demands of tobacco cultivation.

3. Sugar: Sugar was predominantly grown in the Caribbean and parts of the southern colonies, such as Louisiana. It was not a significant crop in the Chesapeake region, so it did not contribute to the expansion of the slave labor system there.

4. Cotton: Cotton became a major cash crop in the southern United States, particularly in the Deep South, after the invention of the cotton gin in the late 18th century. However, it was not a significant crop in the Chesapeake region during the period when the slave labor system was expanding there.

Therefore, the correct answer is tobacco, as it was the primary crop driving the demand for slave labor in the Chesapeake region.
