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.

[Q]: Question: Does ondansetron reduce the shivering threshold in healthy volunteers?
Answer: /b>. Ondansetron appears to have little potential for facilitating induction of therapeutic hypothermia.
[A]: no

[Q]: Question: Does brivaracetam differentially affect voltage-gated sodium currents without impairing sustained repetitive firing in neurons?
Answer: The lack of effect of BRV on SRF in neurons suggests that the reported inhibition of BRV on VGSC currents does not contribute to its antiepileptic properties.
[A]: yes

[Q]: Question: Does platelet-derived growth factor expression correlate with tumor grade and proliferative activity in human oligodendrogliomas?
Answer: The results of this study showed that MIB-1 LI is a rapid and cost-effective modality for predicting tumor grade in oligodendrogliomas. Immunohistochemistry for PDGF was found to be useful in differentiating various grades of oligodendroglioma, and therefore, it may be involved in tumor cell proliferation and malignant transformation. Platelet-derived growth factor receptor alpha, although expressed in oligodendroglial neoplasms, was not found to be useful in predicting tumor grade.
[A]:
yes
