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 high expression of Cullin1 indicate poor prognosis for NSCLC patients?
Answer: These data suggested that Cullin1 might promote the progression of NSCLC and be a biotarget for NSCLC's therapy.
Example Output: yes

Example Input: Question: Are synovial Cytokines and the MSIS Criteria Useful for Determining Infection Resolution After Periprosthetic Joint Infection Explantation?
Answer: IL-6 and IL-1β demonstrated high sensitivities to diagnose PJI and showed the greatest decrease between first and second stages, which may potentially be used to monitor treatment response to PJI. However, cytokines and MSIS criteria had low sensitivity to rule out infection before reimplantation.
Example Output: no

Example Input: Question: Is infection with multiple viruses associated with increased disease severity in children with bronchiolitis?
Answer: Disease severity in children with bronchiolitis is not associated with infection by multiple viruses. We conclude that other factors, such as age, contribute to disease severity to a larger extent.
Example Output:
no
