Why does it make sense to believe that the wire can also be a source of moving charge??
The question is referring to a circuit.

Because the copper atoms in the wire contain electrons. So picture it like a pipe completely full of water. You push 1 ounce in the front and out the back comes 1 ounce of water, even if the pipe is a mile long. It's not the same water you pushed in, though. So the pipe could be considered the source of the water.

Not exactly sure what you mean here. A wire is usually the medium for the electrons to travel along. The only "source" that I can think of is that metal wires are good conductors because they often have more "free" electrons. But you can't create a current without an external power source to generate a voltage differential.

It is all relative motion. If a wire moves and cuts a magnetic field an electric Current in the wire is produced.
Any material contains moving charges. However metals have the greatest moving charges. These moving charges are called free electrons.
