PLEASE HELP ASAP!! I WILL MARK YOU BRAINEST. This question is about World War 1.

What roles did militarism, alliances, imperialism, and nationalism play in the outbreak of war in Europe?

Explanation:

Imperialism, nationalism and militarism were all political situations that European countries were dealing with. They were taking over each other's territories, building up their defenses and had people that were so loyal to their own nation they would do anythng for their own country. This is where the assination of Archduke Franz Ferdinand comes in. An extreme-nationalist, Gavrilo Princip shot him and his wife, Sophie. Everyone started blaming each other and a war resulted.

this isn't a question and if you're going to list things be kind and use commas.

the correct answer option is: weapons.

explanation:

tensions rose as the two opposing superpowers competed for 'weapons'.

referring to the cold war (1945-1991), the two superpowers, usa and ussr, experienced a phase of struggle and conflict with each other. these two superpowers considered each other as a threat to their survival and thus opted for policies to strengthen their positions.

the two superpowers never went to war with each other directly but competed for weapons to preserve their positions.
