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 combined isometric and vibration training enhance strength beyond that of isometric training alone?
Answer: The present study provides evidence to suggest that there are no greater gains to be incurred by the addition of a vibratory stimulus to traditional strength training.
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: Is routine post-operative intensive care necessary for children with obstructive sleep apnea at high risk after adenotonsillectomy?
Answer: Our data confirm high rates of AE after AT for high risk patients, however, only 8% suffered a severe AE truly necessitating care in ICU. This outcome was very unlikely if an AE did not occur in PACU. We therefore conclude that routine post-operative ICU care for high risk children may be avoided if prolonged monitoring in the PACU is possible, with admission to ICU reserved for high-risk children with an early AE.
Example Output:
no
