Question 1: Why did the type of warfare illustrated in the picture develop during World War I?
Correct Answer: D. Trench warfare developed due to the advancements made in artillery that occurred before the development of advanced military mobility.
Explanation: During World War I, the advancements in artillery, which included more powerful and accurate weapons, made it difficult for armies to move across open ground without suffering heavy casualties. As a result, soldiers dug trenches for protection, leading to the stalemate and static warfare characteristic of the Western Front.
Question 2: What military weapon advancement led to the end of trench warfare?
Correct Answer: C. The invulnerability of the tank to machine gun and rifle attack decreased the tactic.
Explanation: The development and deployment of tanks during World War I made it possible to break through entrenched positions and overcome the stalemate of trench warfare, as tanks could protect their crews from small arms fire and barbed wire, leading to more mobile warfare.
