How do trade agreements like NAFTA increase trade?

NAFTA was the first time two developed nations signed a trade agreement with an emerging market country. Through NAFTA, the three signatories agreed to remove trade barriers between them. By eliminating tariffs, NAFTA increased investment opportunities. Hope Im correct! Maybe a thanks or a brainliest will make my day (^U^)

i think that it would be tenth of the first

while it was true that the cotton gin reduced the labor of removing seeds, it did not reduce the need for slaves to grow and pick the cotton.

explanation:

before eli whitney's invention of the cotton gin, picking and cleaning cotton was a slow, labor-intensive job. workers, usually slaves, had to pick the seeds from the cotton fibers by hand. this invention made it possible to grow large amounts of cotton on big farms and make money.
