    Your answer for A looks good.

    For B, i would say skeletal, muscular, and nervous systems, since without the nervous system the body wouldnt receive the signals it needed to move in the first place.

    For C, i would say that you can measure the position and speed of Peter and his bike as he rides. And possibly the amount of Work that peter is doing to ride his bike uphill.
