Task: Wrong Candidate Generation
Input (English): Context: It only looked bad . Right after , my scraped skin was red , but by the next day , it was a deep purple colour . It was good that I had taken a shower , since you are not supposed to wash the affected area for at least 12 hours . Maybe it did not hurt because other parts of my body still hurt from my long bike ride . 
Question: What may have been the reason my skin was scraped and red ? 
Correct Answer: I had an accident with my bike during which I fell on the ground .
Output (English): I fell against the water knobs while in the shower .
