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 glutamine supplementation prevent bacterial translocation after non-lethal haemorrhage in rats?
Answer: Glutamine supplementation before haemorrhage did not reduce bacterial translocation to mesenteric lymph nodes in this rat model.
Example Output: no

Example Input: Question: Is retinol-binding protein-4 strongly associated with insulin sensitivity in normal pregnancies?
Answer: The increased fat mass and insulin resistance during normal pregnancy was best explained by measures of fat mass. However, the increase in RBP4 from early to late pregnancy, associated with a decline in insulin sensitivity, potentially indicates interactions with glucose metabolism.
Example Output: no

Example Input: Question: Are inflammatory biomarkers predictive of intermediate-term risk of ventricular tachyarrhythmias in stable CHF patients?
Answer: No correlation was found between plasma levels of IL-6, TNF-alpha, hsCRP and BNP and ventricular arrhythmic events among stable HF patients during an intermediate term follow-up of 5.1 months. Further studies are still required to assess the association between these biomarkers and long-term risk of ventricular tachyarrhythmia.
Example Output:
no
