Final answer:
Social relativism's problem is that it suggests all societal beliefs are equal, which may not necessarily be true. It encourages understanding and tolerance, and posits that moral understanding is not universal but context-specific.
Step-by-step explanation:
The problem with social relativism as reflected in the options provided is Option 1: It promotes the idea that all beliefs of different societies are equal. Social relativism is the belief that moral practices and beliefs are relative to cultural or societal context, thus suggesting that all such beliefs are equivalently valid or justifiable, which may not necessarily be the case. While it promotes understanding and tolerance (as in Option 4), it does not inherently challenge cultural diversity (Option 2), nor does it emphasize universal moral values (Option 3), as it actually posits the opposite: that moral understanding is context-specific and not universal.
