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.

Example Input: Question: Is mRNA expression of RRM1 , ERCC1 and ERCC2 associated with chemosensitivity to cisplatin , carboplatin and gemcitabine in human lung cancer cell lines?
Answer: These in vitro results suggest that further studies are needed to evaluate the expression of the RRM1, ERCC1 and ERCC2 genes as predictive biomarkers for sensitivity to platinum agents and gemcitabine.
Example Output: no

Example Input: Question: Do lactotripeptides lower ambulatory blood pressure in untreated whites : results from 2 controlled multicenter crossover studies?
Answer: The data do not support a BP-lowering effect of LTPs in whites.
Example Output: no

Example Input: Question: Is evidence that pairing with genetically similar mates maladaptive in a monogamous bird?
Answer: These findings provide evidence that breeders in a genetically monogamous species may avoid the fitness costs of reproducing with a genetically similar mate. In such species that lack the opportunity to obtain extra-pair fertilizations, mate choice may therefore be under high selective pressure.
Example Output:
yes
