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: Question: Are group 2 innate lymphoid cells ( ILC2s ) increased in chronic rhinosinusitis with nasal polyps or eosinophilia?
Answer: As ILC2s are elevated in patients with CRSwNP, they may drive nasal polyp formation in CRS. ILC2s are also linked with high tissue and blood eosinophilia and have a potential role in the activation and survival of eosinophils during the Th2 immune response. The association of innate lymphoid cells in CRS provides insights into its pathogenesis.
Example solution: yes
Example explanation: The answer clearly says that ICLSs are elevated, which is exactly what the question asks. Hence, the output will be yes and it is correct.

Problem: Question: Does anticoagulant or aspirin treatment affect the positive predictive value of an immunological fecal occult blood test in patients undergoing colorectal cancer screening : results from a nested in a cohort case-control study?
Answer: The positive predictive value of i-FOBT for significant neoplasia is not affected by ongoing anticoagulant or chronic low-dose aspirin therapy. This finding suggests that there is no need to interrupt these treatments before i-FOBT for CRC screening.

Solution: no
