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 clinical and serum-based markers associated with death within 1 year of de novo implant in primary prevention ICD recipients?
Answer: Individuals with more comorbidities and elevation of specific serum biomarkers were at increased risk of all-cause mortality despite being deemed as having a reasonable 1-year life expectancy. A simple risk score composed of readily available clinical data and serum biomarkers may better identify patients at high risk of early mortality and improve patient selection and counseling for primary prevention ICD therapy.
Example Output: yes

Example Input: Question: Does long-term treatment with methotrexate or tumor necrosis factor alpha inhibitors increase epstein-barr virus load in patients with rheumatoid arthritis?
Answer: Long-term usage of methotrexate or TNFalpha inhibitors in patients with RA does not significantly influence EBV load in PBMCs.
Example Output: no

Example Input: Question: Is biofilm formation a prerequisite for production of the antibacterial compound tropodithietic acid in Phaeobacter inhibens DSM17395?
