Answer:
Assumptions about how people should think, behave, and communicate
Explanation:
People in different cultures are raised in different ways. As they grow, they learn the appropriate modes of behaviour according to their culture, and they are positively reinforced if they behave in such way, and reprimanded if they behave in the contrary way.
As a result, intercultural communication can be difficult because people will not necessarily understand that many of their assumptions are relative, not absolute truths.
