Not sure what the options are, can you provide them?
Answer: kurgans (burial mounds) of the Eurasian steppes. The hypothesis suggests that the Indo-Europeans, a nomadic culture of the Pontic-Caspian steppe (now part of Eastern Ukraine and Southern Russia), expanded in several waves during the 3rd millennium BC.
Explanation:
The most widely accepted proposal about the location of the Proto-Indo-European homeland is the steppe hypothesis, which puts the archaic, early and late PIE homeland in the Pontic–Caspian steppe around 4000 BC. The leading competitor is the Anatolian hypothesis, which puts it in Anatolia around 8000 BC.
The correct answer is D. unfamiliar with the geography and terrain.
The Continental Army, lead by George Washington, squared off with the British army during the American Revolution. During this time, the colonists were extremely unorganized, had little supplies, and was staffed by thousands of volunteers.
However the Continental Army did have an advantage in knowing the geography/climate. Considering the volunteer soldiers for the Continental Army lived in the 13 colonies (where the fighting took place) the geography and terrain was very familiar to them.
