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 neamine inhibit oral cancer progression by suppressing angiogenin-mediated angiogenesis and cancer cell proliferation?
Answer: Neamine effectively inhibits oral cancer progression through inhibition of tumor angiogenesis. Neamine also directly inhibits proliferation of certain types of oral cancer cells. Therefore, neamine has potential as a lead compound for oral cancer therapy.
Example Output: yes

Example Input: Question: Does ischemic preconditioning attenuate renal ischemia-reperfusion injury by inhibiting activation of IKKbeta and inflammatory response?
Answer: The evidence suggests that IKKbeta may play a role in renal I/R injury and give rise to the generation of NGAL. It appears that IPC may attenuate renal injury and the expression of NGAL following acute I/R injury. IKKbeta may offer a clinically accessible target for preventing renal injury following I/R.
Example Output: yes

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
