Explanation:

Question 16

Eli Whitney invented the cotton gin, which revolutionized cotton processing by separating cotton fibers from seeds efficiently. The steam engine was not his invention, the steel plow was by John Deere, and the mechanical reaper by Cyrus McCormick.

In the 1840s, the Irish Potato Famine (a severe crop failure) led to mass starvation and poverty in Ireland, pushing many to immigrate to the US. Political freedom, religious persecution, and industrial jobs were not the primary reasons for this wave.

The Erie Canal connected the Hudson River to the Great Lakes, creating a waterway that reduced shipping costs and time for goods, boosting trade and transportation in New York. It did not slow shipping, increase grain costs, or reduce cities.

Answer:

B. Cotton gin
