based on the media I've seen covering this country, to me it seems like the people living in NK are fearing their lives everyday. Apart from that, NK is a dictatorship. That alone tells me that certain things available in other countries won't be available in NK. For example, world wide internet access is not available to citizens, only a few high ranked officials have access to it. Another example, is that citizens are not prohibited to travel around the country, let alone abroad, and im pretty sure India, China, Japan, and South Korea let their citizens travel abroad. I know this was very bad explanation, but I hope it helped anyways.
I have no idea what book or story you are talking about, but based on my knowledge of Law... asking a person the same question over and over and cause a reaction in their fight or flight extinct, the person will start to become worried and they'll either start changing their answer or they'll break down completely. I'm guessing the when Hathorne asked the same question several times to Sarah, she started to get nervous.
The Neolithic Age was a major change in the way humans lived their lives. During the Paleolithic Age, humans were hunter-gatherers and nomads. As a result of the Neolithic Age, an excess of food supplies led to the growth of civilizations.
