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 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.
Example Output: yes

Example 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.
Example Output: yes

Example Input: Question: Does exogenous Sonic hedgehog protein rescue cultured intestine from atresia formation?
Answer: Shh and Foxf1 expression are disrupted in atresia formation of distal colon, thereby serving as potential markers of atretic events. Application of exogenous SHH (in media supplement or as a point source bead) is sufficient to induce Foxf1 expression, but insufficient to rescue development of distal colonic mesoderm in Fgfr2IIIb(-/-) mutant embryos. Shh signal disruption is not the critical mechanism by which loss of Fgfr2IIIb function results in atresia formation.
Example Output:
no
