Answer 7

I would go with A
A machine may have one simple function, if you add more simple functions it becomes more complex.

Answer 8

I would go with D

Answer 9

I would also go with D. B& C are out of the question. The problem with A, is that there is no such thing as a "basic" machine unless you use it interchangeably with simple. If that was the case then A would not be the right answer. Also not all simple machines are comprised of just one piece. For instance a door - knob is basically a wheel and and axle combined to give leverage, but has two parts to it. So I would with D.
