The answer is c. to your question
How did slaves in Ancient Greece differ from models of slavery in later societies?
Answer- Slavery was not connected with race in the ancient world. People were slaves because their side lost a recent war or as punishment for a crime (something still theoretically allowed in the US). They were not necessarily of a different race to the slave owners.
People didn’t necessarily see slaves as inferior. Slaves were sometimes employed as secretaries and tutors and it was prestigious to own an intelligent, educated, slave.
If the example I gave is what you mean by the question, then it would be a comma. I hope this helps!
Ex:
"It gives us goosebumps",
The answer is b- the harsh ethics to the lifeboat become even harsher when we consider the reproductive differences between rich nations
