Answer:
A. Internet access would be widespread and uncensored
Step-by-step explanation:
The societies that are culturally isolated are very restricted by their governments. The governments tend to implement policies which do not allow for contact with the other societies. They tend to censor most of the things, including the social media (if its allowed at all), and the cultural products from the other places in the world are forbidden or minimized. This results in isolation of the people from that society, so their culture is unaffected by the other cultures, often making that society far behind the others. A prime example of this is North Korea in the modern world.
