In the early times many European countries were regarded the leaders, especially when they started colonizing different companies. However, this trend earned them a superiority which meant that labor ran short. Overtime, none of the Europeans were doing any manual labor which led to shortage. To furnish this shortage, slaves were imported from Africa to do the manual labor for the Europeans.
This set the ground for the different roles of ethnicities and is still the basis of racism today. Many different races are still fighting for equality. Over time, certain people have opened up to embrace different ethnicities. However, we still have to introduce more diversity to help people understand the concept of equality.
The answer to this question is B. The scarcity of labor led to the import of African Slaves. There were a lot of European countries that were considered to be the leaders when they were colonizing different countries. There came a time when there weren’t enough people to do manual labor anymore and they had to import people from Africa so that they could become slaves.
This may be one of the reasons why a lot of people are still fighting for equality up till now. There are so many things that have occurred in history that shaped the way that people think. Hopefully, change will allow people to become more open-minded and will think of all people as equal.
