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: 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.

Ex Output:
yes

Ex Input:
Question: Is the female protective effect in autism spectrum disorder mediated by a single genetic locus?
Answer: The results do not support the hypothesis that the FPE is mediated by a single genetic locus; however, this does not exclude the possibility of multiple genetic loci playing a role in the FPE.

Ex Output:
no

Ex Input:
Question: Does sevoflurane alter norepinephrine-induced intracellular Ca ( + ) changes in the diabetic rat aorta?
Answer: Sevoflurane at clinically relevant concentrations inhibited the NE-induced increase in [Ca(+)](i) in the aortic smooth muscle from normal rats but not in that from type 2 DM rats. Thus, a Ca(+)- signalling pathway resistant to sevoflurane appears to exist in the type 2 DM rat aorta.

Ex Output:
no
