Triple Entente: This was an alliance formed before World War I between France, Russia, and Britain. It's like three friends promising each other they'll stick together no matter what happens on the playground.
Central Powers: These were Germany, Austria-Hungary, Ottoman Empire during World War I - kind of like another group of friends who decided they needed their own pact because they didn't get along with Triple Entente gang.
Neutrality Acts: These were laws passed in 1930s to prevent the US from getting involved in foreign wars. It's like deciding not to take sides when two groups of friends are fighting.
