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 repeated sputum microscopy essential for monitoring tuberculosis treatment response?
Answer: The yield of a second on-the-spot sputum specimen is negligible, provided that the first smear is from an overnight specimen. From the data available, it is evident that repeated follow-up smears are not essential for documenting treatment outcome.
Example Output: no

Example Input: Question: Is health seeking behaviour of parents of burned children in Bangladesh related to family socioeconomics?
Answer: Education, economic condition and place of residence were found as the contributory factors in choosing service provider. Education to the parents can contribute in changes in health seeking behaviour which ultimately contribute in reducing morbidity and mortality from childhood burn injuries. Including parent's education a national burn prevention program needs to be developed to combat the devastating child injury, burn.
Example Output: yes

Example Input: Question: Do empirical aminoglycosides for peritonitis affect residual renal function?
Answer: In our patients, there was no evidence of an accelerated decline in RRF when using an empirical regimen containing aminoglycosides for peritonitis. Because there are few data to contradict this finding, we recommend the continued use of these drugs in peritonitis regimens, even in patients with significant RRF.
Example Output:
no
