Question

which best describes military strategy during world war i?

a. artillery and machine guns caused armies to stay in defensive positions.

b. new technology decreased the need for troops and military drafts.

c. fast communications allowed nations to change sides quickly as conditions changed.

d. tanks and planes allowed armies to quickly move deep into enemy territory.

Explanation:

• Option A: In WWI, artillery and machine guns had high firepower, making offensive charges very costly. Armies often dug into trenches (defensive positions) as attacking was too dangerous.
• Option B: New tech like machine guns increased the need for troops to hold lines, and drafts were common. So B is wrong.
• Option C: WWI alliances were mostly fixed; nations didn’t switch sides quickly due to communications. C is incorrect.
• Option D: Tanks and planes were in early, limited forms in WWI. They didn’t enable deep, quick advances (that came more in WWII). So D is wrong.

Answer:

A. Artillery and machine guns caused armies to stay in defensive positions.
