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 Q]: 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.
[EX A]: yes

[EX Q]: Question: Is muscle dysfunction during exercise of a single skeletal muscle in rats with congestive heart failure associated with reduced muscle blood supply?
Answer: The cause of contractile dysfunction in a single exercising skeletal muscle in rats with CHF cannot be explained simply by reduced blood supply. In addition, absence of changes in high-energy phosphates and metabolites indicate that the oxidative metabolism of SOL is intact in rats with CHF.
[EX A]: no

[EX Q]: Question: Are fitness and abdominal obesity independently associated with cardiovascular risk?
Answer: Higher fitness and lower waist circumference are each independently associated to a similar extent with a lower CVD risk. Simultaneous evaluation of both fitness and abdominal obesity status in clinical practice is important.
[EX A]:
yes
