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: Are standard equations accurate in assessing resting energy expenditure in patients with amyotrophic lateral sclerosis?
Answer: We found that standard equations used to calculate energy expenditure were not valid for patients with ALS. Moreover, the majority of our patients were either overfed or underfed. As underfeeding can cause diaphragm impairment, and overfeeding can increase ventilatory load, indirect calorimetry should be considered in ALS patients to determine optimal caloric requirement.
Example Output: no

Example Input: Question: Does transdermal oxygen improve sternal wound oxygenation in patients recovering from cardiac surgery?
Answer: Additional inspired oxygen improved Pao(2) and sternal wound PsqO(2) after bypass and may, consequently, reduce infection risk. However, oxygen insufflated locally into an occlusive dressing did not improve wound PsqO(2) and, therefore, does not appear to be useful clinically in cardiac surgery patients to reduce sternal wound infections.
Example Output: no

Example Input: Question: Does transgenic disruption of glucocorticoid signaling in mature osteoblasts and osteocytes attenuate K/BxN mouse serum-induced arthritis in vivo?
Answer: Disruption of GC signaling in osteoblasts significantly attenuates K/BxN mouse serum-induced autoimmune arthritis in mice. These data suggest that osteoblasts modulate the immune-mediated inflammatory response via a GC-dependent pathway.
Example Output:
yes
