The answer that best fits this question is B) How cultural values shift during a crisis.
There are negative impacts of scarcity, but this shows more how people changed the way they acted in order to make up for the lack of items.
It is not easy to alter mainstream cultural norms. As soon as the supplies come back, people will go back to their methods.
People today do have more goods then they need, but this passage does nothing to illustrate that.
I hope this helps! :)
