Which of the following is a general theory in geography that can be used to quantify and predict the interaction between two cities based on population sizes, distance between the places, the number of
migrants moving from one place to the other, or the flow of trade goods between the two locations?

Europe needs to build a trump-like wall that will spread across europe making it impossible for migrants to cross they need to spread pig guts all over this wall so the muslims will never consider crossing into europe..you might be asking "can't they just fly over with planes? " well yes they can so we will install thaad missile protections system to shoot down any aircraft that violates europe's air fourth would be to start a fourth reich in germany.. last but not least.. make europe great again!
