Answer:
B) Maurya Empire
Explanation:
After the death of Alexander the Great in 323 BC, most of present-day India, Pakistan, and Afghanistan were united by the Maurya Empire, which existed from 322 BC to 185 BC. This empire was the largest political entity to have existed on the territory of the Indian subcontinent (you can see the map below).
Both Harappa (3300 to 1300 BC) and Nanda (5th or mid-4th century BC to 322 BC) existed earlier and didn't include all of the listed territories. Qin dynasty was the first Imperial dynasty of China, so answer D is also incorrect.
General Robert E. Lee surrendered at Appomattox Courthouse on April 9, 1865.
The invention of the cotton gin affected slavery because this new invention made the separation process for cotton much easier. When cotton is picked it must be separated from its seeds and the cotton gin did this in a mechanized way thus increasing the potential output of cotton fields and increasing the overall supply of cotton. As the cotton gin helped the cotton industry boom, there was a much higher demand for slavery.
