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: Is patient satisfaction biased by renovations to the interior of a primary care office : a pretest-posttest assessment?
Answer: Renovating the interior of a primary care office was associated with improved patient satisfaction, including satisfaction in domains otherwise unchanged. Physician skills and patient satisfaction sometimes depend on surrounding factors that may bias the ability of patients to assess the quality of medical care. These biases should be taken into account when quality assessment instruments are designed for patients.

Ex Output:
yes


Ex Input:
Question: Is inhibition of B-NHEJ in plateau-phase cells a direct consequence of suppressed growth factor signaling?
Answer: The results document a rapid and fully reversible adaptation of B-NHEJ to growth activity and point to factors beyond EGFR in its regulation. They show notable differences in the regulation of error-prone DSB repair pathways between proliferating and non proliferating cells that may present new treatment design opportunities in radiation therapy.

Ex Output:
no


Ex Input:
Question: Does an oligosaccharide sialyl-Lewis ( x ) analogue reduce myocardial infarct size after ischemia and reperfusion in dogs?
Answer: We conclude that CY-1503 does not substantially or consistently reduce myocardial infarct size or neutrophil accumulation in dogs subjected to ischemia followed by a prolonged period (48 hours) of reperfusion.

Ex Output:

no
