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 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.
[EX A]: yes

[EX Q]: Question: Does health-related quality of life differ between short-term , long-term and very long-term cancer survivors in the Swedish general population?
Answer: Although HRQL was similar between short-term, long-term and very long-term survivors, when compared with the background population, findings suggest that some functional impairments and symptoms are present even at 5-10 YSD.
[EX A]: no

[EX Q]: Question: Do somatic ERCC2 mutations correlate with cisplatin sensitivity in muscle-invasive urothelial carcinoma?
Answer: Somatic ERCC2 mutations correlate with complete response to cisplatin-based chemosensitivity in muscle-invasive urothelial carcinoma, and clinically identified mutations lead to cisplatin sensitivity in vitro. Nucleotide excision repair pathway defects may drive exceptional response to conventional chemotherapy.
[EX A]:
yes
