How many national goverments are in a country

It should be one national government per country. If it has subsections, like states, there would be a government for that state. (State governments)

The US has 50 state governments (because there are 50 states) and 1 national government.

well that depends on how deep the hole is. you'd first go through te crust of the earth, then the upper mantle, then the lower mantle then the outer core, then the inner cor then you'd be stuck in the core to melt.
