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 remote ischemic preconditioning affect the incidence of acute kidney injury after elective abdominal aortic aneurysm repair?
Answer: RIPC did not reduce the risk of postoperative renal failure or myocardial injury in patients undergoing open AAA repair. The authors' results do not support the introduction of this technique to routine clinical practice.
Example Output: no

Example Input: Question: Is planimetry of aortic valve area using multiplane transoesophageal echocardiography a reliable method for assessing severity of aortic stenosis?
Answer: Planimetry of aortic valve area by TOE is difficult and less accurate than the continuity equation for assessing the severity of aortic stenosis.
Example Output: no

Example Input: Question: Are four mutations in Epidermodysplasia verruciformis 1 ( EVER1 ) gene contributors to susceptibility in RRP?
Answer: The absence of these mutations in RRP patients might indicate that EVER 1 alleles are not associated with susceptibility to RRP, or that other, as yet unidentified, mutations in the Epidermodysplasia verruciformis 1 gene, might account for the susceptibility to RRP.
Example Output:
no
