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: Does local adenovirus-mediated transfer of C-type natriuretic peptide suppress vascular remodeling in porcine coronary arteries in vivo?
Answer: Adenovirus-mediated CNP gene transfer with the IABC system may be a useful gene therapy to prevent restenosis after PTCA in vivo.
Example Output: yes

Example Input: Question: Is cYP3A5 genotype associated with a higher risk of acute rejection in tacrolimus-treated renal transplant recipients?
Answer: We conclude that patients expressing CYP3A5 need more tacrolimus to reach target concentrations and have a lower tacrolimus exposure shortly after transplantation. This delay in reaching target concentrations, however, did not result in an increased incidence of early BPAR and therefore, genotyping for CYP3A5 is unlikely to improve short-term transplantation outcome.
Example Output: no

Example Input: Question: Does topical pimecrolimus prolong clear graft survival in a rat keratoplasty model?
Answer: Topical immunosuppression with pimecrolimus does not prolong graft survival in the allogeneic keratoplasty rat model.
Example Output:
no
