please read this question and explain why answer is 1.

the stable functioning of a society depends upon the relatively long0term stability of the goals of its citizens. this is clear from the fact that unless the majority of individuals have a predictalbe and enduring set of aspirations, it will be impossible for a legislature to craft laws that will augment the satisfactino of the citizenry, and it should be obvious that a society is stable only if its laws tend to increase teh happiness of its citizens.

the claim that a society is stable only if ..................... happiness of citiznes...., play which one of the following roles?

1. it helps to support the conclusion of the argument

2 is incorrect because the argument isn't presupposing "that a society is stable only if its laws tend to increase the happiness of its citizens." The argument is explicitly stating it to support the conclusion that "the stable functioning of a society depends upon the relatively long term stability of the goals of its citizens."
