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 catecholamine release induce elevation in plasma lactate levels in patients undergoing adrenalectomy for pheochromocytoma?
Answer: Catecholamine release caused by surgical manipulation may be a possible cause of intraoperative transient lactic acidosis, and it should be considered as a differential diagnosis of intraoperative lactic acidosis. Intraoperative peak plasma lactate level was correlated with preoperative epinephrine-releasing activity.
Example Output: yes

Example Input: 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.
Example Output: no

Example Input: Question: Does genetic deletion of dectin-1 affect the course of murine experimental colitis?
Answer: Together our data suggest that, although at the immune cell level there is a difference in response towards the intestinal flora in dectin-1 deficient macrophages, during intestinal inflammation this response seems to be redundant since dectin-1 deficiency in mice does not affect intestinal inflammation in experimental colitis.
Example Output:
no
