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.

Input: Consider Input: Question: Do expanded effector memory T-lymphocytes in DBA/2 mice inhibit the growth of SL2 tumours?
Answer: SL2 tumours induce expansion of effector memory lymphocytes in DBA/2 mice. However, expanded effector memory lymphocytes do not inhibit the growth of tumours.

Output: no


Input: Consider 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.

Output: no


Input: Consider Input: Question: 's it only what you say , it 's also how you say it : communicating nipah virus prevention messages during an outbreak in Bangladesh?
Answer: During outbreaks, one-way behaviour change communication without meaningful causal explanations is unlikely to be effective. Based on the cultural context, interactive communication strategies in lay language with supporting evidence can make biomedical prevention messages credible in affected communities, even among those who initially invoke supernatural causal explanations.


Output: no
