Answer 1

Ответ:

The World War I began on July 28, 1914 and ended on November 11 , 1918

Answer 2

World War I, also known as the First World War or the Great War, began on July 28, 1914, when Austria-Hungary declared war on Serbia. The conflict lasted until November 11, 1918, when an armistice was signed, effectively ending the hostilities. The Treaty of Versailles, which officially ended the state of war between Germany and the Allied Powers, was signed on June 28, 1919. Therefore, the war effectively ended in 1918, but the formal peace settlement was reached in 1919.
