In 1793, Eli Whitney invented the cotton gin, a machine to remove cotton from the seeds. This great invention allowed one field
hand to do the same amount of work as ten, which meant more cotton could be cleaned and prepared. Which statement below
describes a negative outcome of this invention?

A) Other planters built similar copies of the cotton gin machine and made
money off their design.

B) More people were needed to plant and pick cotton so plantation owners
used slaves to fill these positions.

C)In the decade following the invention, cotton production rose from 3.000
bales a year to 100,000 bales a year.

D) Great Britain and other European countries wanted to use the cotton to
make clothes, so there was an increase in demand.
