Final answer:
The Irish famine and political unrest in Germany were two conditions in their native countries that caused immigrants to come to the United States.
Step-by-step explanation:
Based on the provided graph, two conditions in their native countries that caused immigrants to come to the United States are the Irish Famine and the Political Unrest of 1857 in Germany. The Irish famine, which occurred during the mid-19th century, led to a severe lack of food in Ireland, causing many Irish people to emigrate to the United States in search of a better life. Similarly, the political unrest in Germany in 1857 created an unstable environment, prompting some Germans to flee to the United States for safety and economic opportunities.
