Electrical Energy Conversion

It is difficult to answer this question. Please help to work out the detailed step-by-step answers to it. All ac voltages and currents are rms values unless noted otherwise. For three-phase circuits, all voltages are line-to-line voltages unless noted otherwise ... *(Please see 5 page attachment for question)

I am attaching a scanned image of a question. Please show the answer and the method used to obtain the answer. Thanks,

AC sine wave

An AC sine wave is applied to the input of a full wave rectifier. The output of the full wave rectifier is then applied to a half wave rectifier. The output of the half wave rectifier will most closely resemble: the original sine wave? An inverted form of the original sine wave? the output of the full wave rectifier? none of these above? Please elaborate...Thanks
