    Answer:

    The neighbour

    Double your work

    Explanation:

    Work is a product of force and distance, expressed as W=Fd where W is work in Nm, F is applied force and d is the distance in m

    Since your neighbour pushes 4 times then you just push 1m when he pushes 4m, that is an example. Also, since the neighbour only exerts half the force ie 0.5N then you exert full force of 1N

    Work from your neighbour will be 4d*0.5F=2dF

    Work from you will be dF

    Clearly, 2dF=2(dF) hence the neigjbour exerts double work
