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 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.

Ex Output:
no


Ex Input:
Question: Are biphasic redistribution of muscarinic receptor and the altered receptor phosphorylation and gene transcription underlying mechanisms in the rat heart during sepsis?
Answer: The m2AChR in the rat heart was externalized from light vesicles to sarcolemma (overexpression) during early sepsis but internalized from surface membranes to intracellular sites (underexpression) during late sepsis. Furthermore, changes in the receptor phosphorylation and gene transcription are responsible for the biphasic redistribution and the altered expression of m2AChR in the rat heart during the progression of sepsis.

Ex Output:
yes


Ex Input:
Question: Is acrolein exposure associated with increased cardiovascular disease risk?
Answer: Regardless of its source, acrolein exposure is associated with platelet activation and suppression of circulating angiogenic cell levels, as well as increased CVD risk.

Ex Output:

yes
