Answer 2

Answer:

World War I (often abbreviated as WWI or WW1), also known as the First World War or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. Contemporaneously described as "the war to end all wars",[8] it led to the mobilisation of more than 70 million military personnel, including 60 million Europeans, making it one of the largest wars in history.[9][10] It is also one of the deadliest conflicts in history,[11] with an estimated nine million combatants and seven million civilian deaths as a direct result of the war, while resulting genocides and the resulting 1918 influenza pandemic caused another 50 to 100 million deaths worldwide.
