Explanation:

The Irish Potato Famine (Great Famine) was caused by potato blight (disease - infected potatoes). The famine led to widespread starvation, poverty, and a large - scale emigration of Irish people, with many moving to the United States in search of a better life. “People farming corn instead” is not a main result of the famine, and the government did not mainly loan farmers money as a result of the famine.

Answer:

Irish people moving to the U.S.
