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 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.

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: Does calreticulin contribute to C1q-dependent recruitment of microglia in the leech Hirudo medicinalis following a CNS injury?
Answer: These data give new insight into calreticulin/C1q interaction in an immune function of neuroprotection, suggesting another molecular target to use in investigation of microglia reactivity in a model of CNS injury.

Ex Output:

yes
