I chose the correct answer, but I am confused by what the passage says in lines 13-19.
It seems to me that Schwartz is saying Rembrandt did not get along with "circle of patrons," being either his clients, or fellows in his business. Then, Alpers says "Rembrandt refused to submit to the prevailing patronage system." That doesn't seem contradictory to me. It seems Alpers is also saying that Rembrandt did not get along with his patrons.
Am I interpreting these lines incorrectly?
