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: Is [ The increase in the speed of the pulse wave associated with elevated central blood pressure in hypertensive patients with kidney disease ]?
Answer: In hypertensive patients with renal disease PWV is increased, but not the AIx. We believe that the AIx is not a reliable measure of arterial stiffness in hypertensive patients with kidney disease.
[EX A]: no

[EX Q]: Question: Do alpha-2 adrenoreceptors probably mediate the immobility produced by inhaled anesthetics?
Answer: Although stimulation (agonism) of alpha-2 adrenoreceptors can decrease the inhaled anesthetic concentration required to produce immobility in the face of noxious stimulation, blockade of alpha-2 adrenoreceptors minimally affects the concentration. Thus, augmentation of the effect of alpha-2 adrenoreceptors is not an appreciable part of the mechanism whereby inhaled anesthetics produce immobility.
[EX A]: no

[EX Q]: Question: Does serum -hydroxybutyrate ( -HB ) predict elevated 1 h glucose levels and early-phase -cell dysfunction during OGTT?
Answer: Fasting serum -HB levels predicted elevated 1h glucose during OGTT, potentially due to impaired insulin secretion kinetics. This association persisted even in patients with an otherwise normal insulin-glucose homeostasis. Measuring serum -HB could thus provide a rapid, inexpensive screening tool for detecting early subclinical hyperglycemia, -cell dysfunction, and increased risk for diabetes.
[EX A]:
yes
