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 sympathetic nerve activity reduce proprioceptive acuity in humans?
Answer: The present findings contradict previous reports from animal studies and the hypothesis that sympathetic nerve activity reduces proprioceptive acuity.
Example Output: no

Example Input: Question: Does multidisciplinary care improve amputation-free survival in patients with chronic critical limb ischemia?
Answer: MDC pathways for the management of a population of CLI patients improved AFS by greater than twofold and should be the standard of care for the CLI population. Baseline nonambulatory status and unrevascularized patients also predict worse AFS. Wound healing remains prolonged regardless of preoperative or postoperative wound care. Future study is required to evaluate the costs and functional outcomes for MDC in the management of CLI.
Example Output: yes

Example Input: Question: Does a negative nontreponemal and/or specific antitreponemal IgM test exclude active infectious syphilis : evidence from a rabbit infectivity test : A case report?
Answer: The definitive differential diagnosis of active infectious syphilis should be reconsidered. Moreover, selecting the appropriate penicillin preparation is important because T pallidum can reside in sequestered sites. It is necessary to treat a patient with known invasion of the central nervous system with aqueous crystalline penicillin G, if previous treatment for syphilis failed and patients had some clinical neurological presentation that is otherwise unexplained, but that could represent neurosyphilis. Additional studies are needed to confirm the results in other syphilis patients.
Example Output:
no
