问题 Passage Two [br] What is the advantage of laughing gas over other more advanced options?

选项

答案 It doesn’t need a professional anesthesiologist．

解析第6段提到了推广笑气的原因，最后两句都表明就算一些小型医院没有常驻的麻醉师，产妇自己就可以使用笑气，由此可见，与其他更先进的麻醉手段相比，笑气的优点就在于它不需要专业的麻醉师，所以本题答案是It doesn’t need a professional anesthesiologist，其中professional一词可省。
