Scientists did not find it problematic to explain the physical world with nonphysical phenomenon in seventeenth-century England. Though Bacon did.
A) No Change
B) England, but Bacon did.
C) England; Bacon did.
D) England like Bacon.
The correct answer is B, but I chose D. I thought a comma was necessary between two independent clauses and a coordinating conjunction. However, "Bacon did" isn't a complete thought.
Can someone please help me see what I'm missing?
