I'm looking over this question again and I'm still having problems
understanding why three NMOS and three PMOS transistors don't work. For
instance, isn't the circuit in problem 6 made up only of NMOS and PMOS
transistors? I thought that even though they aren't good at transmitting
both types of signals, because they are used in conjunction it works out?

I know it's late, but I'd appreciate any clarification. Thanks

Remember that NMOS and PMOS aren't good at transmitting both high and low
voltages. Each is only good for one of the two. Additionally, remember
that you cannot assume access to complemented inputs for this problem.
