Question

which of the following weapons helped continue the stalemate on battlefields during world war i?

• the tank
• the submarine
• the fighter plane
• the machine gun

Explanation:

During World War I, the machine gun was a key weapon that contributed to the stalemate on battlefields. It had a high rate of fire, allowing defenders to mow down large numbers of advancing troops, making it difficult for either side to gain significant ground and leading to the trench warfare stalemate. Tanks were introduced later and helped break through trenches, submarines were mainly for naval warfare, and fighter planes were more for air combat and reconnaissance rather than directly causing the stalemate on land battlefields.

Answer:

the machine gun
