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.

Ex Input:
Question: Does aerobic training alter CRP in apparently healthy , untrained men?
Answer: Regular aerobic training does not appear to affect CRP concentrations in apparently healthy, untrained men despite significant improvements in bodyweight, BF%, BMI, and VO2max.

Ex Output:
no


Ex Input:
Question: Are antihelminthic benzimidazoles novel HIF activators that prevent oxidative neuronal death via binding to tubulin?
Answer: These studies demonstrate that tubulin-binding drugs can activate a component of the hypoxic adaptive response, specifically the stabilization of HIF-1α and its downstream targets. Tubulin-binding drugs, including antihelminthic benzimidazoles, also abrogate oxidative neuronal death in primary neurons. Given their safety in humans and known ability to penetrate into the central nervous system, antihelminthic benzimidazoles may be considered viable candidates for treating diseases associated with oxidative neuronal death, including stroke.

Ex Output:
yes


Ex Input:
Question: Is structural pathology related to patient-reported pain and function in patients undergoing meniscal surgery?
Answer: Specific meniscal pathology and other structural joint pathologies found at meniscal surgery were not associated with preoperative self-reported pain and function in patients with meniscal tears questioning inferences made about a direct relationship between these. Our findings question the role of arthroscopic surgery to address structural pathology as a means to improve patient-reported outcomes in patients having surgery for a meniscal tear.

Ex Output:

no
