3. Why did many farmers want cotton gins? 4. How did the cotton gin expand the need for slave labor in the South?Explain.

3. Farmers wanted cotton gins because these machines revolutionized the process of separating cotton fibers from seeds. Before the cotton gin, this task was labor-intensive and time-consuming. The invention significantly increased the efficiency of cotton processing, allowing farmers to produce larger quantities of cotton in less time.4. The cotton gin expanded the need for slave labor in the South by dramatically increasing the profitability of cotton cultivation. With the ability to process cotton more quickly and on a larger scale, the demand for cotton grew, leading to a surge in plantation-based agriculture. As a result, plantation owners sought more labor to cultivate and harvest larger cotton crops, and slavery became integral to the economic success of the Southern cotton industry.
