Which of the following is an example of trench warfare? a. an army drops bombs from the air to defeat the enemy b. an army uses tanks to conquer an enemy city c. an army digs a long hole in the ground to protect territory d. an army fires machine guns at the enemy in the open

Hello Swagger, so to understand how to get the right answer to this question, you must know what trench warfare is. Now trench warfare is basically a type of combat in which opposing troops fight from trenches facing each other. Now we can obviously eliminate A and B because that has nothing to do with hiding or being in a trench. Its the same reason why D isn't the answer as well. The correct answer here is C because a trench is a long hole that is dug mainly by soldiers, in which they can use as a defense or combat. Hope this helped, if you have any questions, please ask!
