not just because A1 but by A2.
在这里A1中所说的很贵的药并不是主句发生的原因，不过A2是主句发生的原因。

not just by the fact....but also by the fact...和not just because of... but by the fact相比，前者更符合平行架构要求。在两个都冗长的情况下，选更平行的那个。

1）句意理解：导致处方药支出增加的原因是药变贵了（过程）并且医生开的处方药更贵了（动作）；而不是因为expensive drug（本身贵)；所以应该用从句表达出这个意思；而不是用because of + Noun
2) explain和becuase 不能重复使用，否则造成冗余
3) which 不能指代前面整句话，只能指代名词
