Answer 2

Germany invaded Austria

Step-by-step explanation:

Great Britain entered World War I on 4 August 1914 when the King declared war after the expiration of an ultimatum to Germany. The official explanation focused on protecting Belgium as a neutral country; the main reason, however, was to prevent a French defeat that would have left Germany in control of Western Europe.
