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.

Ex Input:
Question: Does combination of dehydroepiandrosterone and orthovanadate administration reduce intestinal leukocyte recruitment in models of experimental sepsis?
Answer: Our results indicate that DHEA is able to reduce intestinal leukocyte recruitment induced by experimental sepsis. Combination of DHEA with OV inhibits leukocyte adherence to intestinal endothelium, similar to what is achieved by the single administration of DHEA but with significantly improved FCD. These findings suggest a potential role for DHEA and OV in clinical sepsis.

Ex Output:
yes

Ex Input:
Question: Do armband activity monitor data correlate with reported pain scores in patients receiving vertebroplasty?
Answer: Activity monitors can be used to objectively record changes in activity following vertebroplasty procedures. Patient-reported pain or disability scores do not correlate with activity monitor-measured activity or sleep metrics.

Ex Output:
no

Ex Input:
Question: Is upregulation of lipocalin-2 ( LCN2 ) in osteoarthritic cartilage necessary for cartilage destruction in mice?
Answer: Our observations collectively suggest that upregulation of LCN2 in OA cartilage is not sufficient or necessary for OA cartilage destruction in mice.

Ex Output:
no
