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 Input:
Question: Is weight-adjusted resting energy expenditure constant in critically ill patients?
Answer: Predictive equations were not able to estimate measured REE adequately in all the patients. Adjusted REE decreased with increasing body mass index; thus, a body mass index group-specific adaptation for the estimation of energy needs should be applied.

Ex Output:
no


Ex Input:
Question: Do norepinephrine and ephedrine counteract the increase in cutaneous microcirculation induced by spinal anaesthesia?

Ex Input:
Question: Does the spectrum of structural abnormalities on CT scan from patients with CF with severe advanced lung disease?
Answer: A CT scoring system was developed to characterise the structural abnormalities in patients with SALD. A wide spectrum was observed in SALD, ranging from predominantly air trapping to predominantly infection/inflammation-related changes. This spectrum may have clinical implications for patients with SALD.
