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: Does racemic ketamine abolish cerebrovascular autoregulation in the pig?
Answer: We conclude that autoregulation of CBF is not abolished during continuous ketamine infusion in normoventilated pigs and that previous divergent conclusions are unlikely to be associated with severe impairment of cerebrovascular autoregulation.
Example Output: no

Example Input: Question: Does star-shaped tetraspermine enhance cellular uptake and cytotoxicity of T-oligo in prostate cancer cells?
Answer: SSTS significantly enhanced therapeutic benefits associated with the use of T-oligo and can be developed as a delivery vehicle for its in-vivo therapeutic applications.
Example Output: yes

Example Input: Question: Are gastric and gall bladder emptying of a mixed meal coordinated in liver cirrhosis -- a simultaneous sonographic study?
Answer: These results indicate the lack of coordination between gastric and gall bladder emptying in liver cirrhosis. They also support the hypothesis that diminished gall bladder contractility might contribute to the increased gallstone formation in liver cirrhosis.
Example Output:
no
