Question

ultimately, even though the populist party failed to win the presidency and it folded, it was very successful because:
famers became quite prosperous by 1900
it united black and white farmers
it moved the two major parties to begin recognizing and addressing some of the needs of the nation instead of catering to big business and party patronage
it forced the federal government to go on the silver standard

Explanation:

The Populist Party, though it didn't win the Presidency and dissolved, influenced the two - major parties to address national needs instead of just big - business and party interests. Farmers did not become prosperous by 1900, and the party's unity of black and white farmers was limited and short - lived. Also, it did not force the federal government to go on the silver standard.

Answer:

It moved the two major parties to begin recognizing and addressing some of the needs of the nation instead of catering to big business and party patronage
