Am I understanding correctly: it is false in the real world because it is not true that everyone is at least 20 (because they do not both have to be true)? Thank you so much for your help--it is really, really appreciated!

And for the second part, would the second equation be saying that everybody is at least 20 years old or everybody is less than 20, but NOT both?

Thank you! For the first example (Some citizens are unhappy in countries ruled by dictators), could it be: Pxy = x is a citizen of country y Ux = x is unhappy Dy = y is a country ruled by a dictator Ex(Pxy ∧ Dy -> Ux)? Sorry for formatting!
