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 pseudomonas aeruginosa in CF and non-CF homes found predominantly in drains?
Answer: These findings implicate drains as important potential sources of P. aeruginosa infection. They suggest that maximizing P. aeruginosa control efforts for drains would reduce exposure with minimal extra burden to CF patients and families.
Example Output: yes

Example Input: Question: Does transparent and open discussion of errors increase malpractice risk in trauma patients?
Answer: A transparent discussion of errors, complications, and deaths does not appear to lead to an increased risk of lawsuit.
Example Output: no

Example Input: Question: Do fasting hyperinsulinaemia and 2-h glycaemia predict coronary heart disease in patients with type 2 diabetes?
Answer: Fasting insulin levels are positively associated with incidence of CHD in T2D. Furthermore, 2hPG appears to be a significant predictor of incident CHD independently of other risk factors, including HbA1c. These findings suggest that strategies targeting the reduction of insulinaemia and post-load glycaemia may be useful for preventing cardiovascular complications.
Example Output:
yes
