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 epidural analgesia superior to local infiltration analgesia in children with cerebral palsy undergoing unilateral hip reconstruction?
Answer: Epidural analgesia is superior to local infiltration analgesia for early postoperative pain management in children with cerebral palsy who undergo unilateral hip reconstruction.

Output: yes


Input: Consider Input: Question: Do gene expression and genetic analysis reveal diverse causes of recessive self-compatibility in Brassica napus L?
Answer: The recessive SC in eight accessions is caused by the loss of function of BnSCR-7 and BnSCR-6 in pollen. Translational repression contributes to the recessive SC in three accessions, whose SRK and SCR genes were expressed normally and had identical CDSs to BrS-29 or BoS-15. SI in 11 F1 hybrids relies on the expression of BnSCR-1300 rather than SRK genes. Other factor(s) independent of the S locus are involved in recessive SC. Therefore, diverse causes underlie recessive SC in B. napus, yielding insight into these complex mechanisms.

Output: yes


Input: Consider Input: Question: Do unaffected family members report improvements in daily routine sun protection 2 years following melanoma genetic testing?
Answer: Members of high-risk families reported increased daily routine sun protection and decreased sunburns 2 years following melanoma genetic testing, with no net decline in sun protection following negative test results. Thus, genetic testing and counseling may motivate sustained improvements in prevention behaviors.


Output: yes
