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: Does high expression of Cullin1 indicate poor prognosis for NSCLC patients?
Answer: These data suggested that Cullin1 might promote the progression of NSCLC and be a biotarget for NSCLC's therapy.

Ex Output:
yes


Ex 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.

Ex Output:
no


Ex Input:
Question: Does an imbalance between apoptosis and proliferation contribute to follicular persistence in polycystic ovaries in rats?
Answer: These results show that the combination of weak proliferation indices and low apoptosis observed in follicular cysts, could explain the cause of the slow growth of cystic follicles and the maintenance of a static condition without degeneration, which leads to their persistence. These alterations may be due to structural and functional modifications that take place in these cells and could be related to hormonal changes in animals with this condition.

Ex Output:

yes
