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: Is acinetobacter baumannii infection in prior ICU bed occupants an independent risk factor for subsequent cases of ventilator-associated pneumonia?
Answer: ICU admission or the hospitalization of patients infected by Acinetobacter baumannii increases the risk of AbVAP by subsequent patients.

Output: yes


Input: Consider Input: Question: Are levels of soluble CD30 in cord blood and peripheral blood during childhood correlated with the development of atopic disease or a family history of atopy?
Answer: These findings indicate that the sCD30 concentration in cord blood is not a reliable prognostic indicator of, nor a useful diagnostic marker for, atopic disease in children up to 7 years of age. If such correlations do exist, they might be masked by age-dependent variations in the circulating levels of sCD30, which may reflect individual differences in the maturation of children's immunological responses.

Output: no


Input: Consider Input: Question: Is expression of SOCS3 throughout liver regeneration regulated by DNA methylation?
Answer: DNA methylation or demethylation seems to be a relatively stable modification of cytosine, but not a dynamic and reversible process to regulate gene transcription in daily and acute pathophysiological events.


Output: no
