What was one way the us government responded to this combination of events

The correct answer to this open question is the following.

You did not mention the kind of event you are referring to, neither the time in US history. You also did not attach the options of the question.

However, doing some research, it seems that you are referring to the strict legislation the United Stated federal government had to make after the wave of immigration to America.

So one way the US government responded to this combination of events was to pass immigration restrictions.

The US federal passed the Johnson-Reed Act, commonly known as the Immigration Act of 1924. This legislation established a quota based on nationality origins to provide visas and allow the entrance of foreign people to the country.

they remained in rural areas and worked at jobs such as lumbering or farming.

the group i'm selecting: greeks.

a first group of greek immigrants came to the us in the 1850s. the second group came to america starting in the 1890s due to economic opportunities they didn't have back in their home caused by the hardships of ottoman rule. greek immigration was 90% male, many of them expected to work and return to greece after earning enough capital, but ultimately had to remain in the us after the greek genocide.
