Question

which best describes the effects of the new technologies of the 1830s, including the deere plow, the cotton gin, and the mccormick reaper? they decreased the amount of product that farmers could sell. they helped the transportation industry become more efficient. they increased agricultural productivity and efficiency. they angered farmers who preferred to do their work by hand.

Explanation:

The Deere plow, cotton gin, and McCormick reaper were agricultural innovations. The Deere plow improved plowing efficiency, the cotton gin sped up cotton processing, and the reaper aided in harvesting. These technologies were designed to make farming tasks faster and more productive, directly increasing agricultural productivity and efficiency. The first option is incorrect as while production increased (which could lead to more sales), the primary effect of these tools was on production efficiency, not just sales volume. The second option is wrong because these are agricultural, not transportation, technologies. The fourth option is incorrect as there's no historical evidence these technologies angered most farmers; they were generally adopted for their benefits.

Answer:

They increased agricultural productivity and efficiency.
