Craft one correct answer to the question given in input. To make it more interesting, try to use non-stereotypical language if possible. Make sure your correct answer is reasonably long, consistent with the context, and requires common sense (instead of explicit extraction from the context.) In your answer, use as few words as possible from the given context. Use a response that is uncommon/non-stereotypical, so that it is less predictable. To be less repetitive, please vary your language for each question.

Context: I checked my rig , sat in my seat and took the oars . Time to focus . Big water lay waiting downstream , a string of serious and reverent names like Horn Creek , Granite , Hermit and Crystal . As our group pushed off and my boat swung out into the Bright Angel riffles , I started to sing Do n't Fence Me In , and , you know , I think I never sounder better . 
Question: What may be the reason why they were singing so good ?
Because they were relaxed .

Context: I swear I even walked backwards for a while cause it did n't hurt so bad . I 'll be fine , its just part of the process . I hope someday I look back after I finish a full marathon and think , geez I was being a big baby after that half . 
Question: Why may the narrator be sore in the coming days .?
They just ran a marathon .

Context: If I count backward , the lap naps started shortly after he stopped going down for naps with minimal fuss - right after the horrible day I discovered that he could , if he so chose , scream for two hours . Which would have been around week thirty - seven , thirty - eight maybe . Oh , earthquake . Okay , back now . 
Question: Why might he scream for 2 hours ?

It might be that he is not comfortable and have to express it .
