100,000

3 million

20 million

35 million

The correct answer is "20 million".

Explanation:

1870 to 1915 was a period of exponential growth of North America economy, particularly from United States industrialization and urbanization. This attracted millions of people around the world looking for a better life following the Civil War. It is estimated that around 20 million people migrated to the United States, the majority from Southern, Eastern and Central Europe, but by 1907 many people from Japan settle in large cities of America. It is estimated that by 1910, three-quarters of New York City’s population were new immigrants and first-generation Americans.

from the religious point of view, the conflicts began because of the enmity between catholic and protestants. in 1649, at the insistence of baltimore, the colonial assembly approved the act of religious tolerance, the first law in the colonies granting freedom of worship, though only for christians. in 1654, however, with the protestants of maryland in the majority, the act was revoked. the almost civil war broke out and order was not restored until 1658, when lord baltimore was returned to power.

on the issue of class conflict, the chesapeake region offered few economic opportunities to contract employees who had served their term of obligation. even with the small amount of capital needed to grow tobacco, former hired servants at best became subsistence farmers, a mature class for those called to rebellion, such as those proposed by nathaniel bacon. as the number of new hired workers declined because of limited chances of progress and reports of severe treatment, they were replaced by african slaves.

from the racial point of view, after 1660, the chesapeake colonies imposed laws that defined slavery as a lifelong and hereditary condition based on race. this made slaves profitable because planters could rely not only on their work but also on their children. the slave population, which numbered four thousand in virginia and maryland in 1675, grew significantly by the end of the century.
