@sweingar okay so we are looking at these two sentences correct? "The stable functioning of a society depends upon the relatively long-term stability of the goals of its citizens." "This is clear from the fact that unless the majority of individuals have a predictable and enduring set of aspirations, it will be impossible for a legislature to craft laws that will augment the satisfaction of the citizenry, and it should be obvious that a society is stable only if its laws tend to increase the happiness of its citizens." If so, you always want to ask yourself which of these supports the other? Notice that the first sentence is support by the second sentence. Why is it the case that, "The stable functioning of a society depends upon the relatively long-term stability of the goals of its citizens"? Well, because, "unless the majority of individuals have a predictable and enduring set of aspirations, it will be impossible for a legislature to craft laws that will augment the satisfaction of the citizenry, and it should be obvious that a society is stable only if its laws tend to increase the happiness of its citizens." This is why the first sentence is the conclusion. Hope that helps! Please let us know if you have any other questions.

This is very helpful.
