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.

Input: Consider Input: Question: Does in vivo gene transfer of endothelial nitric oxide synthase to carotid arteries from hypercholesterolemic rabbits enhance endothelium-dependent relaxations?
Answer: Adenovirus-mediated gene transfer of eNOS to carotid arteries of cholesterol-fed animals improves endothelium-dependent relaxation when an optimal viral titer is administered.

Output: yes


Input: Consider Input: Question: Does histologic evaluation of in vivo femtosecond laser-generated capsulotomies reveal a potential cause for radial capsular tears?
Answer: Femtosecond laser can perform a capsulotomy with high reliability. In comparison to a highly experienced cataract surgeon, the achieved results in size are similar. In terms of circularity, the femtosecond laser was superior the manual procedure. Better refractive outcomes based on a 360°-degree optic overlap seem to be possible, especially for less experienced surgeons.

Output: yes


Input: Consider Input: Question: Are human enteroviruses the cause of neurological impairments in children at the Korle-Bu Teaching Hospital?
Answer: Non-polio enteroviruses and chikugunya virus were found not to be the etiologic agent responsible for the convulsion with neurologic morbidity observed in the Ghanaian children. Investigation for other viral agents is recommended.


Output: no
