Answer :
Details about the number of slaves working cotton 20 years after the cotton gin would best support the author's claim that more slaves were needed after the invention of the cotton gin . Option D is correct .
Who is Whitney?
The cotton gin's most well-known inventor was Eli Whitney, but he was also known as the father of the mass production method. He figured out how to machine-make muskets in 1798 so that the parts could be swapped out.
Although the invention of the cotton gin made it easier to remove seeds, it did not eliminate the need for slave labor to grow cotton and pick it. Actually, the opposite took place. Enslaved people demanded a lot more land and enslaved labor because cotton farming was so lucrative for them.
Whitney never would have invented it if he had known how his invention would affect slavery.
