Task: Question Answering
Input (English): Context: I can summarize it no other way . There was the occasional nausea , but nothing that ever ventured into uncomfortable territory . I never felt like I was going to vomit , but then , taking the better part of 3 hours to sip a mug of Ayahuasca brew is probably not going to have that effect . 
Question: Why might this person have nausea ?
Output (English): Because they do n't feel well.
