It's important to note that the argument says drugs are a necessary part of the treatment OF ALL PATIENTS WHO RECEIVE THEM. Do you see the distinction? It is not that drugs are a necessary part for all treatment of back muscle injuries, just that when they are given, they are deemed a necessary part of the treatment.

Thus, as answer choice (B) explains, if specialists made accurate judgments about who needs both drugs and physical therapy and who needs just physical therapy, then it makes sense that bot groups of patients will do as well as each other, since only the ones that the specialists give drugs to are the ones that need it.

Answer choice (D) does nothing to fix the paradox. Regardless of whether a few back muscle injuries that were aggravated by improper attempts at physical therapy were successfully treated with drugs does not explain why why some patients who only receive physical therapy from medical specialists do as well as those who receive both physical therapy and drugs.

Hope that clears things up! Please let us know if you have any other questions.
