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: Is vincristine-induced neuropathy in the rat modified by drug-drug interactions with the P-glycoprotein inhibitor verapamil?
Answer: Behavioral pain tests did not reveal an increase in vincristine neurotoxicity following combination treatment with verapamil and vincristine. This regimen only led to a slight increase in general toxicity.
Example Output: no

Example Input: Question: Do flavonoids from Inula britannica L. inhibit injury-induced neointimal formation by suppressing oxidative-stress generation?
Answer: Our results suggest that TFE inhibit the neointimal hyperplasia after balloon injury, at least partly, by suppressing oxidative-stress generation.
Example Output:
yes
