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 Q]: 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 A]: no

[EX Q]: Question: Does expression of the pair-rule gene homologs runt , Pax3/7 , even-skipped-1 and even-skipped-2 during larval and juvenile development of the polychaete annelid Capitella teleta support a role in segmentation?
Answer: C. teleta eve, Pax3/7 and runt homologs all have distinct expression patterns and share expression domains with homologs from other bilaterians. None of the pair-rule orthologs examined in C. teleta exhibit segmental or pair-rule stripes of expression in the ectoderm or mesoderm, consistent with an independent origin of segmentation between annelids and arthropods.
[EX A]: no

[EX Q]: Question: Is qT dispersion related to infarct size or inducibility in patients with coronary artery disease and life threatening ventricular arrhythmias?
Answer: QT parameters are not influenced by infarct size and do not predict inducibility during electrophysiological study in patients with coronary artery disease and malignant ventricular arrhythmias. In contrast, the amount of scar tissue determined by perfusion imaging is strongly correlated with inducibility.
[EX A]:
no
