Answer
Brief Explanations:
Tanks were introduced in World War I. They had armor that could withstand enemy fire and could cross trenches. This made trench warfare less effective as a defensive strategy. Tanks did not cause the war to last longer (they were more of a tool to break stalemates). They were not ineffective against Central Powers' weapons (they had some success). And they did not increase trench warfare use in World War II (WWII had different tactics like blitzkrieg).
Answer:
The tank ended the use of trench warfare.
