To defend territory would be the correct answer.
Germany's invasion on poland started it. Hope this helps!
The correct answer is B, as at the conclusion of the Spanish-American war, the United States gained an empire and new stature in world affairs.
In fact, as a result of the defeat, Spain ceded its territories of the Philippines, Guam and Puerto Rico to the Americans. In this way the US obtained territories in strategic points of the world (Caribbean, Oceania and Southeast Asia), with which its power in front of the rest of the nations was increased.
In addition, the fact of having defeated a colonial power gave the United States a new status as a world power, both politically and militarily.
The correct answer to this open question is the following.
As news traveled to Europe, other countries, many of whom were not on friendly terms with England, were shocked at the American victory at Saratoga. What some of these countries decide to do was to support the Continental Army and the 13 colonies. The Americans hoped other countries will help the Continental Army as a result of this major victory.
And indeed that was what happened. The French decided to ally with the American colonies and they sent weapons and supplies to the American colonies in order to help the Continental Army to defeat the British troops.
At that time, Great Britain had many enemies, the French being one of them.
After the Continental Army victory in the Battle of Saratoga, the help received from France was vital to win the Revolutionary War and finally getting independence from the English crown.
