5.Medical specialists report that patients with back muscle injure who receive a combination of drugs and physical therapy do only as well as those who receive physical therapy alone.Yet the specialists state that drugs are a necessary part of the treatment of all patients who receive them for back muscle injuries.

要求选出最能妥协specialist 两个论断的选项.答案是:"Medical specialists who prescribe these treatments make accurate judgments about who needs both drugs and physical therapy and who needs physcial therapy alone."

我怎么看也看不出这个答案可以整合文中的两个论断.文中最后是说drugs+therapy是所有患者治疗措施中必要的一部分,怎么和答案联系起来呢?
