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 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 output: 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.
Q: Question: Is ureteric duplication a contraindication for robot-assisted laparoscopic radical cystoprostatectomy and intracorporeal Studer pouch formation?
Answer: Duplicated ureters might be underdiagnosed on CT. The presence of a duplicated ureter is not a contraindication to RALRCP and intracorporeal Studer pouch formation. The da Vinci-S surgical robot is very safe for performing this complicated procedure. Frozen section analysis of ureters during radical cystectomy for bladder cancer might not reliably diagnose the pathologic condition and might overestimate the disease in the ureters.
A:
no
