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 apoptosis inhibitor-5 overexpression associated with tumor progression and poor prognosis in patients with cervical cancer?
Answer: API5 expression is associated with pERK1/2 in a subset of cervical cancer patients and its expression predicts poor overall survival, supporting that API5 may be a promising novel target for therapeutic interventions.
Example Output: yes

Example Input: Question: Is cigarette smoking associated with a reduction in the risk of incident gout : results from the Framingham Heart Study original cohort?
Answer: Cigarette smoking is associated with lower incidence of gout and this is not explained by differences in the prevalence of risk factors. The mechanistic underpinnings of this epidemiological finding merits further study.
Example Output: yes

Example Input: Question: Does anterior fascial fixation reduce the parastomal hernia rate after radical cystectomy and ileal conduit?
Answer: Anterior fascial fixation of the ileal conduit does not reduce the risk of parastomal hernia formation compared with the patients treated without fascial fixation. Surgeons should consider avoiding anterior suture fixation during ileal conduit creation.
Example Output:
no
