Question

Which country was the last to join the Allied Powers?

1) Great Britain
2) France
3) United States
4) China

Answer 1

The United States was the last major power to join the Allied Powers in World War I, entering the war in 1917.

Step-by-step explanation:

The country that was the last to join the Allied Powers during World War I was the United States. The Triple Entente, which formed the basis of the Allied Powers, originally consisted of Great Britain, France, and Russia. As the conflict expanded, several other countries joined the Allies, with the United States being the last major power to enter the war on the side of the Allies in 1917. It's worth noting that other nations joined after 1917, including several Latin American nations, but the United States was the final major power to enter the conflict against the Central Powers.
