Answer:
I believe the answer is "Both became allies with Hitler and remained so through the end of World War II." This seems like the most righteous answer I apologize if it is wrong.
Step-by-step explanation:
The reason is that I go through is I go all the ones are wrong. Starting with "Both supported democracy and enacted new voting rights." That is wrong they all hated democracy. Next would be, "Both used propaganda and created totalitarian governments." Only only Benito Mussolini had used this usage of government. Next would have to be, "Both started collectivization to control agriculture and the economy." That one is wrong because it was only Stalin.
