Question

Which statement best describes Germany’s submarine campaign during World War I?

Answer 1

Have you ever heard of "unrestricted submarine warfare?"

Imagine a big ship carrying a bunch of innocent and peaceful people enjoying the cruise.
But the ship might have WEAPONS on it that's being sent to your enemy.

Because of this, in WWI a german submarine fired a torpedo at the ship Lusitania and sank everyone down in it, without even warning them.
