This is a 38 question study guide on the causes and effects of WWI. I have attached the answer key for your convenience. The questions are all standard aligned and contain page numbers that correspond with the textbook Contemporary Cultures: 1400 to Present. However, the questions are essentially universal and the page numbers can easily be removed.
As a bonus, I included an entertaining reading: "If WWI was a Cafeteria Fight". This can be used as a study tool as well to check for understanding.
