The correct answers are:
- were a conquered people;
The slaves in general were people that were conquered, so in way they were war-prisoners. They were obligated to work for their owners, but also had the chance to buy out their freedom (at least in some cases).
- were those with a certain skin color;
Even though it was not the general practice, as people with different physical appearance did not come across very often, still, people that were with different skin color often were taken as slaves if presented the opportunity, and they were in general considered as lesser people.
