D. They could pay soldiers for their service with land rather than money.

Explanation:

The pillage and gift system consisted in the pillaging of conquered lands, and the gift of those lands to the soldiers who helped conquered them in first place.

As the functioning of the system implies, it was used by nobles to pay their soldiers with land instead of currency, since payments in currency form were not always convenient or possible because some nobles could not issue currency, or could do so, but at the cost of debasement and inflation.

when world war i broke out across europe in 1914, president woodrow wilson proclaimed the united states would remain neutral, and many americans supported this policy of nonintervention. however, public opinion about neutrality started to change after the sinking of the british ocean liner lusitania by a german u-boat in 1915; almost 2,000 people perished, including 128 americans. along with news of the zimmerman telegram threatening an alliance between germany and mexico, wilson asked congress for a declaration of war against germany. the u.s. officially entered the conflict on april 6, 1917.
