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: Is a high body mass index in esophageal cancer patients associated with adverse outcomes following esophagectomy?
Answer: A high BMI is not associated with increased overall morbidity following esophagectomy; moreover, it is associated with decreased incidence of chylothorax. The better overall survival in patients with high BMI compared with those with low BMI might be due to a relatively low pathological stage. A high BMI should therefore not be a relative contraindication for esophagectomy.
Example Output: no

Example Input: Question: Does clinical evaluation of pazopanib eye drop versus ranibizumab intravitreal injections in subjects with neovascular age-related macular degeneration?
Answer: Pazopanib was well tolerated. Daily pazopanib eye drops in neovascular AMD subjects did not result in therapeutic benefit beyond that obtained with ranibizumab alone.
Example Output: yes

Example Input: Question: Do meal delivery practices meet needs of Alzheimer patients with increased cognitive and behavioral difficulties in a long-term care facility?
Answer: Delivering excess energy to patients with poor BMIs likely does not result in increased energy consumption. Behavioral and cognitive deterioration leads to a shift in the time of day that energy delivered has an impact on energy consumption, with the most progressed individuals being most impacted by foods delivered in the morning, suggesting that traditional meal practices are inappropriate for elderly individuals with AD.
Example Output:
no
