In 2000, a mere two dozen products accounted for half the increase in spending on prescription drugs, a phenomenon that is explained not just because of more expensive drugs but by the fact that doctors are writing many more prescriptions for higher-cost drugs.
A. a phenomenon that is explained not just because of more expensive drugs but by the fact that doctors are writing
B. a phenomenon that is explained not just by the fact that drugs are becoming more expensive but also by the fact that doctors are writing
C. a phenomenon occurring not just because of drugs that are becoming more expensive but because of doctors having also written
D. which occurred not just because drugs are becoming more expensive but doctors are also writing
E. which occurred not just because of more expensive drugs but because doctors have also written

OA IS B.
Can anyone please explain how B is right? isn't A PHENOMENON explaining prescription drugs i mean prescription drug cannot be a phenomenon. secondly, how is 'not just by' parallel with 'but also by'

THANKS

"prescription drugs" is NOT the phenomenon. The whole phrase - a mere two dozen products accounted for half the increase in spending on prescription drugs - is the phenomenon, and thus an apt modifier.

I do not understand why "not just by", to you, does not appear parallel to "but also by". "Not only by" and "but also by" would have been fine as well.

Option A - not parallel. "Not just because of" and "but also by" are not parallel.
Option B - correct
Option C - drugs are becoming and doctors having written are not parallel.
Option D - which does not have a clear antecedent.
Option E - which does not have a clear antecedent. Structure not parallel.
