Answer 1

Tanks, machine guns, aircraft and chemical weapons were all refined and their technological secrets captured, causing lethal and simultaneously constructive effects. From such analysis, World War One is evident of a major modern turning point in history.

The entry of the United States was the turning point of the war, because it made the eventual defeat of Germany possible. It had been foreseen in 1916 that if the United States went to war, the Allies' military effort against Germany would be upheld by U.S. supplies and by enormous extensions of credit.
