Question

How did new naval technology impact World War I?

A). Germany engaged in unrestricted submarine warfare to gain tactical advantages.
B). The Allies used U-boats to attack and sink German ships without warning.
C). Navies became less focused on manpower since most submarines could operate on their own.
D). War at sea became less deadly since submarines were used to observe the enemy, rather than attack.

Answer 1

Correct answer: A only.

Explanation: Germany's U-boats (submarines) were used in unrestricted submarine warfare to cut Allied shipping and gain a strategic advantage. B is incorrect because it was Germany, not the Allies, that famously used U-boats in that way. C is false — submarines still required trained crews and navies remained manpower-intensive. D is false — submarines made sea warfare more deadly by attacking (not merely observing) enemy and merchant ships.
