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: Do pre-admission clinical factors affect length of stay in the epilepsy monitoring unit?
Answer: Pre-admission clinical variables may predict EMU LOS. These factors could be used at the administrative level for maximum EMU resource utilization.

Ex Output:
yes


Ex Input:
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 Output:
yes


Ex Input:
Question: Does metastasis-associated protein ribosomal RNA processing 1 homolog B ( RRP1B ) modulate metastasis through regulation of histone methylation?
Answer: RRP1B, a breast cancer metastasis suppressor, regulates gene expression through heterochromatinization and transcriptional repression, which helps our understanding of mechanisms that drive prognostic gene expression in human breast cancer.

Ex Output:

yes
