Question

Which of the five principles of politics best explains why the federal government passed the americans with disabilities act of 1990 to adopt uniform standards across the states rather than leave it to the individual states to determine how to increase access to public buildings for the disabled?

Answer 1

This would all be known to be "the collective action principle". They would have rather have the data and etc be passed through Americans with disabilities act of 1990 to adopt uniform standards across the states mainly because they thought that it would practically be a lot faster  than leave it to the individual states to determine how to increase access to public buildings for the disabled. They figured that if they were to do it the way that they did not, it would have a long process in this part, and eventually things would not succeed. And therefore, that would be the reason why it was known to be "the collective action principle".

Answer 2

The correct answer is the collective action principle

This principle revolves around the idea that a group of people should work together in ensuring the well-being of everyone. If they had left it to states, numerous states probably wouldn't bother with such things because of various reasons, either financial or lack of care for people with disabilities. Because of the collective action principle, they now had to help everyone.
