This is my answer and the comment for it was to answer in the greater detail could you tell me where I can expend my answer? Thank you.

Question

1. In your opinion, what is the importance of the United States being "a nation of law, not of any individual, or group of men or women"?
2. How does the idea of a "nation of laws" affect people and governments?

1. In my opinion, the importance of the United States is “a nation of law, not of any individual, or group of men or women” is because of it every citizen the equal, and governed by the same law, no one is allowed to be above the laws.
2. The idea of a “nation of laws” makes people and the government become more aware and responsible for what they do or going to do as their bad behavior will be punished by the laws. Moreover, the government cannot abuse its power as they will also be punished for their bad action.

Answer 1

I've revised your responses to the questions. Basically, I know you understand this concept, but your writing is often wordy. That's easily fixed!

Now -- you can expand each answer by giving specific examples for each one. You don't need more than 1 or 2 examples for each. Dive in!
----------------------------------
1. That the United States is “a nation of law, not of any individual, or group of men or women” is important because every citizen is considered equal to all other citizens, and all are governed by the same laws. No one is to be above the laws.

2. A “nation of laws” means the people and all government units are responsible for what they do, based on laws, not on a king or small group of people. Citizens' bad behavior will be punished by the laws. Moreover, different forms of government also cannot legally abuse their power as they will also be punished for their bad actions.
