Detailed Instructions: 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.
See one example below:
Problem: 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.
Solution: yes
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: Are women who exposed to spermatozoa and infertile women have similar rates of stage I endometriosis?
Answer: From an epidemiologic point of view, stage I endometriosis is not more common in infertile women than in unselected women. However, stage II to IV endometriosis was more frequent in infertile women. Whereas a relation between stage I endometriosis and infertility seems unlikely, the relation between stages II to IV endometriosis and infertility seems possible.
Solution:
no
