Select which government was granted each of the powers listed

Coining of money: FEDERAL GOVERNMENT

Fire and police protection: STATE GOVERNMENT

Schools: STATE GOVERNMENT

Army and Navy: FEDERAL GOVERNMENT

Treaties with other nations : FEDERAL GOVERNMENT

Highways and roads: STATE GOVERNMENT

Local courts: STATE GOVERNMENT

So, I'd say that Coining of Money, Army and Navy, Treaties with other Nations are most powerful.

This probably didn't help but I hope it did! :D
