Which two statements best describes slaves in ancient times?
were a conquered people
were those with a certain skin color
were happy in bondage
were an accepted social class

The first 2:

- Were a conquered people
- Were those with a certain skin color.

The reason after the first statement is that they didn't choose to be slaves. Most of the time they were violently caught from their living countries and then selled.

They were a group of certain skin color because slaves were mostly african people, due to their resistance and the lack of laws that even considered them people (to hold any right).
