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.

Input: Consider Input: Question: Are leg muscle reflexes mediated by cutaneous A-beta fibres normal during gait in reflex sympathetic dystrophy?
Answer: In the acute phase of RSD of the lower extremity there is no evidence for abnormal A-beta fibre-mediated reflexes or for defective regulation of such reflexes. This finding has implications for both the theory on RSD pathophysiology and RSD models, which are based on abnormal functioning of A-beta fibres.

Output: yes


Input: Consider Input: Question: Is prooxidant-anti-oxidant balance associated with extent of coronary artery disease?
Answer: In conclusion, we found higher levels of oxidative stress in CAD+ patients compared to healthy subjects. The oxidation level was not related to measures of the extent of CAD such as number of stenosed vessels.

Output: no


Input: Consider Input: Question: Does l-carnitine reduce doxorubicin-induced apoptosis through a prostacyclin-mediated pathway in neonatal rat cardiomyocytes?
Answer: These findings suggest that L-carnitine protects cardiomyocytes from doxorubicin-induced apoptosis in part through PGI(2) and PPARα-signaling pathways, which may potentially protect the heart from the severe toxicity of doxorubicin.


Output: yes
