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.

[Q]: Question: Do acute pain and central nervous system arousal restore impaired hypoxic ventilatory response during sevoflurane sedation?
Answer: The observation that acute pain caused an increase in baseline ventilation with no effect on the acute hypoxic ventilatory response indicates that acute pain interacted with ventilatory control without modifying the effect of low-dose sevoflurane on the peripheral chemoreflex loop. Acute pain increased the level of arousal significantly during sevoflurane inhalation but did not restore the approximately 30% depression of the acute hypoxic ventilatory response by sevoflurane. The central nervous system arousal state per se did not contribute to the impairment of the acute hypoxic ventilatory response by sevoflurane.
[A]: no


[Q]: Question: Is retinol-binding protein-4 strongly associated with insulin sensitivity in normal pregnancies?
Answer: The increased fat mass and insulin resistance during normal pregnancy was best explained by measures of fat mass. However, the increase in RBP4 from early to late pregnancy, associated with a decline in insulin sensitivity, potentially indicates interactions with glucose metabolism.
[A]: no


[Q]: Question: Does fEV1/FEV6 in Primary Care be a Reliable and Easy Method for the Diagnosis of COPD?
Answer: FEV1/FEV6 <0.72 can be used in primary care as a valid alternative to FEV1/FVC <0.70 as a fixed cutoff point for the detection of COPD in adults. This study suggests that FEV1/FEV6 is an effective and well validated option that should be used in primary care to detect COPD, which is a rampant problem.
[A]:
yes
