Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Example Input: Question: Is nuchal cord associated with adverse perinatal outcome?
Answer: Nuchal cord is not associated with adverse perinatal outcome. Thus, labor induction in such cases is probably unnecessary.
Example Output: no

Example Input: Question: Does bacteriuria in patients with a continent ileal reservoir for urinary diversion regularly require antibiotic treatment?
Answer: The present results indicate that asymptomatic bacteriuria in patients with a continent ileal reservoir for urinary diversion is generally of no clinical importance and should not be treated with antibiotics. This conclusion is based on the observations that the bacterial strains growing in the reservoir changed spontaneously indicating colonization rather than infection. Raised titres of antibodies against E. coli correlated weakly with bacterial growth. The observed elevations in antibody titres were usually just above the normal upper limit.
Example Output: no

Example Input: Question: Does superficial wound infection cause inferior clinical outcome after TKA?
Answer: In a long-term follow-up, a different clinical outcome and HRQoL were not obtained after a successfully treated superficial infection following a TKA when compared to a TKA without complications. Based on the findings of the study, additional complications are not anticipated after a successfully treated superficial wound infection in TKA. Therefore, a different follow-up to that of a non-complicated TKA is not recommended when the early post-operative superficial wound infection has been appropriately treated. A superficial infection successfully treated in the acute post-operative period should be considered solved at long-term follow-up.
Example Output:
no
