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.

Ex Input:
Question: Do rates of labor induction and primary cesarean delivery correlate with rates of adverse neonatal outcome in level I hospitals?
Answer: Crude and adjusted rates of labor induction and PCD vary among level I hospitals, but with no consistent effect on neonatal outcome.

Ex Output:
no

Ex Input:
Question: Is visceral pleural invasion a significant prognostic factor in patients with a part-solid lung cancer?
Answer: VPI may not contribute to the prognosis of patients with part-solid nodules. Thus, upgrading of the TNM stage on the basis of VPI should be carefully considered in these patients.

Ex Output:
no

Ex Input:
Question: Does plasmalogen modulation attenuate atherosclerosis in ApoE- and ApoE/GPx1-deficient mice?
Answer: Plasmalogen enrichment via batyl alcohol supplementation attenuated atherosclerosis in ApoE- and ApoE/GPx1-deficient mice, with a greater effect in the latter group. Plasmalogen enrichment may represent a viable therapeutic strategy to prevent atherosclerosis and reduce cardiovascular disease risk, particularly under conditions of elevated oxidative stress and inflammation.

Ex Output:
yes
