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 angered farmers who preferred to do their work by hand.
they increased agricultural productivity and efficiency.
they decreased the amount of product that farmers could sell.
they helped the transportation industry become more efficient.

Explanation:

The Deere plow, cotton gin, and McCormick reaper were agricultural innovations. The Deere plow made plowing easier, the cotton gin sped up cotton processing, and the reaper improved harvesting. These technologies were designed to make farming tasks faster and more efficient, thus increasing agricultural productivity. The first option is incorrect as there's no evidence these technologies angered hand - working farmers. The third is wrong because these tools would increase, not decrease, the product farmers could sell. The fourth is incorrect as these are agricultural, not transportation, technologies.

Answer:

B. They increased agricultural productivity and efficiency.
