The representative presidential republic is not a patent of the United States, and many western European countries have similar regimes. . .

Everything else is obviously American.

For this kind of question type, the exclusion method can be used without clear grasp, which is a good magic weapon for many liberal arts students. Some ambiguous concepts may be unheard of by yourself, but if there are obvious mistakes in other options, you can make a choice.

If it is a simple question, it will be considered separately. That's how I got here.

I hope this will help you, thank you!
