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: Does novel individual metabolic profile characterize the protein kinase B-alpha ( pkbα-/- ) in vivo model?
Answer: Specific metabolic characterization should be assessed individually. Therefore, our in silico model enables novel insights inaugurating specific primary preventive strategies targeting individual metabolic profiling precisely.
Example Output: yes

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 obesity increase risk of anticoagulation reversal failure with prothrombin complex concentrate in those with intracranial hemorrhage?
Answer: Obesity and elevated initial INR are independently associated with anticoagulation reversal failure using the weight-based PCC protocol in patients with warfarin-related acute ICH. Further studies are needed to determine more effective dosing protocols and individualized strategies for anticoagulation reversal after acute ICH, especially among obese patients.
Example Output:
yes
