Task: Question Answering
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 . 
Question: What is the reason Manji bit down on a peeled stick ?
Output (English): Biting a stick was a way to forget the pain being felt .
