Explanation:

answer to number 4

Explanation:

Though exact totals will never be known, the transatlantic slave trade is believed to have forcibly displaced some 12.5 million Africans between the 17th and 19th centuries; some 10.6 million survived the infamous Middle Passage across the Atlantic. Though descendants of these enslaved Africans now make up considerable segments of the population in the United States, Brazil and many Caribbean islands, written records of their ancestors’ origins are difficult—if not impossible—to find. Through extensive research, however, scholars have been able to make educated guesses about where many of the slaves brought to the New World originated.

in the 1800s, chinese workers migrated to the united states, first to work in the gold mines, but also to take agricultural jobs, and factory work, especially in the garment industry. chinese immigrants were particularly instrumental in building railroads in the american west, and as chinese laborers grew successful in the united states, a number of them became entrepreneurs in their own right. as the numbers of chinese laborers increased, so did the strength of anti-chinese sentiment among other workers in the american economy. this finally resulted in legislation that aimed to limit future immigration of chinese workers to the united states, and threatened to sour diplomatic relations between the united states and china.
