Question

a major reason irish immigrants came to the united states in the 1840s was to find jobs as skilled laborers. to escape a potato famine. to live in less crowded conditions. to escape oppression.

Explanation:

In the 1840s, the Great Potato Famine (caused by potato blight) devastated Ireland, leading to widespread starvation, poverty, and death. This forced many Irish people to immigrate to the United States (and other countries) to escape the famine's effects. Option A is incorrect as Irish immigrants were often unskilled laborers. Option C is incorrect as the main push factor was the famine, not crowding (though Ireland was populated, the famine was the critical driver). Option D is incorrect as oppression was not the primary reason in the 1840s compared to the famine.

Answer:

to escape a potato famine.
