The correct option is: "came to escape famine and starvation."
During the 19th century and until the first half of the 20th century, Europe was the scene of a massive emigration. For lack of work and the misery in which they lived, millions of inhabitants of the countries that today make up the European Union (EU) left for other continents, especially America. These people were mostly from Germany, Ireland, the United Kingdom, Poland, Italy, Croatia, Spain and Portugal.
The United States has been the majority destination of European immigrants. Thus, between 1815 and 1860, five million people from Europe arrived in that country, and between 1860 and 1920, another 27 million entered. Between 1840 and 1920, 6 million Germans, 4.75 million Irish, 4.5 million Italians, 4.2 million English, Welsh and Scottish emigrants, 4.2 million from the Austro-Hungarian Empire, 2.3 million from Scandinavia and 2.3 million from the Russian Empire (particularly Lithuanian Catholics, Poles and Jews). Between 1855 and 1890, 8 million Europeans arrived, between 1905 and 1914 some nine million. In 1907 one million two hundred thousand immigrants entered, the highest annual income. Between 1874 and 1888, 5,881,000 immigrants arrived and between 1904 and 1935 16,878,000. About 370,000 Swedes, Danes and Norwegians emigrated to the United States between 1850 and 1875.
