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 myeloid knockout of HIF-1 markedly affect hemorrhage/resuscitation-induced inflammation and hepatic injury?
Answer: Here, deleting HIF-1 in myeloid cells and thereby in Kupffer cells was not protective after H/R. This data indicates that other factors, such as NF- B, due to its upregulated phosphorylation in WT and KO mice, contrary to HIF-1 , are rather key modulators of inflammation after H/R in our model.
Example Output: no

Example Input: Question: Does an ultrasound-guided fascia iliaca catheter technique impair ambulatory ability within a clinical pathway for total hip arthroplasty?
Answer: BMI affects postoperative ambulation outcome after hip arthroplasty, whereas the type of regional analgesic technique used does not. An ultrasound-guided FIC technique offers similar analgesia with fewer side effects when compared with ITM.
Example Output: no

Example Input: Question: Do human intestinal epithelial cells promote the differentiation of tolerogenic dendritic cells?
Answer: A population of tolerogenic CD103+ DCs was identified in the human gut that probably differentiate in response to IEC-derived factors and drive T(reg) cell development.
Example Output:
yes
