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: 's it just the big kids : both high and low BMI impact bracing success for adolescent idiopathic scoliosis?
Answer: Based on our results, children on either end of the BMI spectrum are more likely to fail brace treatment for scoliosis than their mid-BMI counterparts. In high-BMI patients, this appears to be in large part attributable to an inadequacy of in-brace curve correction as well as to poorer brace compliance, while a low BMI appears to be an independent risk factor for brace failure.
Example Output: no

Example Input: Question: Does diffusion-tensor imaging implicate prefrontal axonal injury in executive function impairment following very mild traumatic brain injury?
Answer: Impaired executive function following mTBI is associated with axonal injury involving the DLPFC.
Example Output: yes

Example Input: Question: Is there substantial nuclear and cellular disintegration before detectable phosphatidylserine exposure during the camptothecin-induced apoptosis of HL-60 cells?
Answer: During CAM-induced apoptosis of HL-60 cells, the external exposure of PS can either precede or follow DNA cleavage, which suggests that PS exposure is not always an indicator of early apoptosis.
Example Output:
yes
