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 tRAIL receptor deletion in mice suppress the inflammation of nutrient excess?
Answer: These data advance the concept that macrophage-associated hepatic and adipose tissue inflammation of nutrient excess requires TR signaling.
Example Output: yes

Example Input: Question: Is exploration under the dome : Esophageal ultrasound with the ultrasound bronchoscope indispensible?
Answer: Operators comfortable with the endobronchial ultrasound scope in both the airway and the esophagus can actively seek and successfully perform biopsy of sub-diaphragmatic abnormalities when present and can thereby add to the diagnostic value of the procedure.
Example Output:
yes
