Anthropological studies indicate that distinct cultures differ in their moral codes.
Conclusion
As long as there are distinct cultures, there are no values shared across cultures.
Evidence
Distinct cultures differ in their moral codes.
Evaluate
Given that ... each culture has a unique moral code How could it be that ... distinct cultures could have shared values?
Well, just because two moral codes are different doesn't mean they're entirely different. They could still have overlapping features.
Goal
Get rid of four answers that help us argue that .
(We could also weaken with an answer that just makes it sounds like the anthropological studies are giving us bad data)
