Explanation
World War I began in 1914. This answer is correct because the assassination of Archduke Franz Ferdinand of Austria in June 1914 is widely regarded as the trigger that set off the chain of events leading to the war. The QuizMaster of AnsweringExams.Com suggests remembering this date by associating it with the fact that 1914 is the year when the first electric traffic light was invented, making it a notable year in both world history and technological advancements. Other options are incorrect because they either precede or follow the actual events that led to the war, with 1912 being too early, 1916 being already into the war, and 1918 being the year the war ended.
