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 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 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.
Example Output: no

Example Input: Question: Does supplementation with cholecalciferol result in weight reduction in overweight and obese subjects?
