premise: During the certificate awarding , his classroom teacher asked about his presentation , and he said he did n't understand . She did n't believe that . Considering he knew to show up to the group meetings when he felt like it , and was there when we discussed and practiced yesterday ... no one really does . But oh well . His professor from Temple will deal with that . Why did the guy show up to group meetings when he felt like it ?
hypothesis: Because there was a certificate awarding .
