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 early removal of central venous catheter in patients with candidemia improve outcome : analysis of 842 patients from 2 randomized clinical trials?
Answer: In this cohort of 842 adults with candidemia followed up prospectively, early CVC removal was not associated with any clinical benefit. These findings suggest an evidence-based re-evaluation of current treatment recommendations.
Example Output: no

Example Input: Question: Does tRAIL receptor deletion in mice suppress the inflammation of nutrient excess?
Answer: These data advance the concept that macrophage-associated hepatic and adipose tissue inflammation of nutrient excess requires TR signaling.
Example Output: yes

Example Input: Question: Does low-dose theophylline exert its anti-inflammatory effects in mild asthma through upregulation of interleukin-10 in alveolar macrophages?
Answer: LDT has an anti-inflammatory effect in asthma; however, this effect is not mediated via the production of IL-10 or the attenuation of GM-CSF or TNF-alpha. The mechanisms of theophylline activity remain to be determined.
Example Output:
no
