False. Experimental drilling has reached depths far beyond the asthenosphere, including the Moho (the boundary between the Earth's crust and mantle) and into the upper mantle. However, drilling into the deeper mantle is currently beyond our technological capabilities. Most deep drilling projects, like the Kola Superdeep Borehole, have only reached a small fraction of the Earth's total depth.

Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.)
