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 learning trajectories of children with special health care need across the severity spectrum?
Answer: Even children with less complex SCHN are at risk for academic failure. Early identification, together with integrated health and educational support, may promote stronger pathways of educational attainment for these children. Achieving these better outcomes will require the involvement of both educational and health practitioners.
Example Output: yes

Example Input: Question: Does the bradykinin B1 receptor antagonist BI113823 reverse inflammatory hyperalgesia by desensitization of peripheral and spinal neurons?
Answer: The selective bradykinin B1 receptor antagonist BI113823 reduces CFA-induced mechanical hyperalgesia which is mediated via antagonism of peripheral as well as spinal bradykinin B1 receptors. The selective modulation of CFA-sensitized spinal NS neurons by BI113823 could be a promising property for the treatment of inflammatory pain.
Example Output: yes

Example Input: Question: Does in human IgA nephropathy uteroglobin play the role inferred from transgenic mice?
Answer: This first report of human IgA nephropathy after the publication of the mouse model shows that UG is not reduced in circulation and is even increased in IgA-Fn complexes. Because aberrant IgA1 glycosylation is the event initiating IgA nephropathy in humans, we speculate that the enhanced incorporation of UG into IgA-Fn complexes might represent feedback to reduce the formation of macromolecular aggregates.
Example Output:
no
