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 hepatic HMOX1 expression positively correlate with Bach-1 and miR-122 in patients with HCV mono and HIV/HCV coinfection?
Answer: HMOX1 and miR-122 play an important role in the pathogenesis of CHC in HCV mono-and HIV/HCV co-infected patients. Reduced expression of HMOX1 in patients with HIV/HCV co-infection may indicate a worse prognosis in this group. Our results do not support the importance of Bach-1 in repression of HMOX1 in patients with chronic hepatitis C.
Example Output: yes

Example Input: Question: Does the presence of the adult respiratory distress syndrome worsen mortality or discharge disability in blunt trauma patients with severe traumatic brain injury?
Answer: The presence of ARDS was not associated with higher mortality or worse discharge disability. It was, however, associated with higher hospital morbidity, longer ICU and hospital length of stay.
Example Output: no

Example Input: Question: Do long-term results from the Contura multilumen balloon breast brachytherapy catheter phase 4 registry trial?
Answer: Use of the CMLB for APBI delivery is associated with acceptable long-term local control and toxicity. Local recurrence-free survival was 97.8% at 3 years. Significant (grade 3) toxicity was uncommon, and no grade 4 toxicity was observed. Treatment at high-volume centers was associated with decreased late toxicity.
Example Output:
yes
