Think more about the four main causes of World War I. Which cause do you think had the biggest impact on starting the war? Which one had the least impact? Rank the causes from one to four in a list. Number one should be the cause that had the biggest impact. Number four should be the cause you think was had the least impact. Feel free to look back through the lessons in this unit or research the topic on the Internet to help you with your ranking. The causes- alliances, militarism, imperialism, nationalism.
Now, justify your ranking from the last part. Briefly make an argument for why you think one cause had a bigger impact than the other causes. Your answer should be about 100 to 150 words long and include evidence to support your argument. The evidence can come from the lessons in this unit or from outside sources. Be sure to list the sources that you used to support your answer.
