Question

how did trench warfare affect the war?

a. flooding in trenches caused more deaths than battles did.

b. major battles caused only a few casualties.

c. major battles gained a lot of ground.

d. major battles gained little or no ground.

Explanation:

In trench warfare (especially in WWI), the elaborate trench systems made it extremely difficult for either side to advance significantly. Major battles often resulted in huge casualties but little territorial gain. Option A is incorrect as battles (not just flooding) caused most deaths. Option B is wrong as major battles had massive casualties. Option C is incorrect as gains were minimal. Option D matches the reality of trench warfare’s impact on territorial gains.

Answer:

D. Major battles gained little or no ground.
