Final answer:
US Imperialism involved the purchase of Alaska, the role of Yellow Journalism in the Spanish-American War, the Platt Amendment in Cuba, the overthrow of Queen Liliuokalani in Hawaii, and the grant of a canal lease by Panama.
Step-by-step explanation:
A. America did pay money for Alaska. It was purchased from the Russian Empire in 1867 for $7.2 million.
B. Yellow Journalism did help push the US into declaring War on Spain. Sensationalized news stories about the sinking of the USS Maine in 1898 played a role in generating public support for war.
C. The Platt Amendment did give the US bases in Cuba. It granted the US the right to intervene in Cuban affairs and establish naval bases on the island.
D. Queen Liliuokalani did not maintain power in Hawaii after the US took over. She was overthrown in 1893 by American planters and business interests.
E. Panama did grant the US a lease to use the canal. The Panama Canal was built by the US after Panama gained independence from Colombia in 1903.
