How does scarcity of resources affect relationships between various groups of people

C. It stops them from fulfilling all of their wants.

Explanation:

Scarcity forces the average person to stop buying a particular item because it costs too much. If there is a high demand and low supply, prices will skyrocket and the middle class cannot afford this. This is just me making up a random explanation because I know the answer is C but I don't know why.

Hope this helps. Let me know.

the indians crossed artificial boundaries, setting the stage for conflict

hello!

according to the passage the most suitable options are two. the first one is "by leading the aef to victory in several key battles" like the battle of saint- mihiel and the battle of cantigny mentioned in the passage you copied here. the second one is "by the aef and allied forces defeat germany" since the passage says that his army destroy the german resistance in the meuse- argonne offensive. and also, "by insisting that the aef operate as an independent force".

hope this
