Task: Question Generation
Input (English): Context: The strange process of expulsion resumed , the hill peaking high with a pulsing movement and the skin tearing open . Rin could only hover in sympathetic agony while Manji bit down on a peeled stick and dug his fingers into the gravel . Again the emergence stopped and the rent began to heal , though the protrusion did n't retreat .
Output (English): Why would someone dig their fingers into gravel ?
