01 By what name was the First World War also known in earlier times?
Answer and explanation
Correct answer: A. Great War
Explanation: The direct answer is A, the Great War. The First World War lasted from 1914 to 1918 and involved many countries from different parts of the world. Before the Second World War occurred, it was commonly called the Great War because people viewed it as an exceptionally large and destructive conflict. After the Second World War, the name First World War became necessary to distinguish it from the later war. Option B, the Cold War, was a long political and military rivalry mainly between the United States and the Soviet Union after the Second World War; it was not the First World War. Option C, the Gulf War, was a much later conflict connected with the Persian Gulf region. Option D, the Korean War, took place from 1950 to 1953 and was also later. Therefore A is correct. Memory cue: World War I was first called the Great War; after World War II, numbering became clearer.
