Can someone please answer these questions for me?:

1. Is it necessary for law to have a moral content?
2. What is difference between non-positivists and positivists as they relate to Law?
3. Should altruism be enforced by adopting duty-to-rescue laws?
4. How do laws emerge, according to the functionalist and to the rationalist view?
5. The reality of law creation can be explained by both consensus and conflict models. Which one better applies in liberal societies?
6. What is 'class instrumentalism', and why it cannot fully account for the emergence of laws?
7. How does the public choice theory explain the creation of laws?
