Contrary to the previous answer to this question, Roman culture very much lived on.As the Western Roman Empire neared its end the Barbarians became "Romanized" in a sense much more than the Romans became "barbarized".
The answer to this question would be B, or the second option.
where soil was really fertile, like in the southern colonies, lots of slave labor was needed to work the plantations. in the middle colonies, there was still slave labor, but not as much because they had less fertile soil, meaning smaller plantations and farms. in the northern colonies, the soil wasn't super fertile, so there was almost no need for slave labor because there weren't a lot of farms.
The correct answer is D) War at Sea.
Although you did not specify what war you are referring to, we are going to assume that you refer to World War I.
The "front" that used torpedoes and submarines was the War at the Sea.
Germany used to have a powerful navy that disrupted the English Sea through the use of torpedos launched by its submarines. Germany had many U-Boats. One of these boats shot a torpedo and sank teh Lusitania ship. which was one of the many motives US President Wilson decided to ask Congress for a declaration of war against Germany. The other major reason was the interception of the Zimmerman telegram in which Germany asked Mexico for its support in the war.
