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 nAT1 genotypes predict response to mesalamine in patients with ulcerative colitis?
Answer: NAT1 genotypes do not predict response or side effects to mesalamine in patients with UC. Variations caused by non-genomic effects may be associated with the clinical response to 5-ASA.

Ex Output:
no

Ex Input:
Question: Does electrical stimulation prior to delayed reinnervation enhance recovery in muscles of rats?
Answer: The primary factors that inhibited reinnervation and recovery following delayed reinnervation were not alleviated by the electrical stimulation during the period of muscle denervation.

Ex Output:
no

Ex Input:
Question: Does monoclonal antibody against transforming growth factor Beta 1 influence liver regeneration after resection in large animal experiments?
Answer: We established a large animal model of toxic liver injury that is comparable with CASH. The toxic injury that was induced without pause between administrations was probably more extensive than occurs in CASH, and there was no effect of MAB-TGF administration on liver regeneration. MAB-TGF administration did not lead to any observable side-effects, indicating that it could be a promising solution for use as an oncologic-targeted treatment.

Ex Output:
no
