Explain some of the problems that might have arisen in countries with more than one cultural group.

- Racism

In countries with more than one cultural group, There is always a chance the ethnics or races that belong in the majority will see themselves as the 'superior' in the country. This will give them with justification to discriminate those who belong in the minority.

- Language barriers.

The more cultural groups exist in the country, the higher the likelihood that different segments of the population will communicate in different language. This could create a problem because when discussing national issues, these different groups need to understand each other. Language barriers might create misunderstanding with one another.

- Lack of representation in the government for the minorities

People tend to vote for the government that they feel can represent them. This make them more likely to choose someone with similar backgrounds (whether it's based on race, ideologies, religion, etc). This make the group with lesser population will have lack of representation in the government.
