I chose A while the answer is supposed to be
The board of trustees of the Fernando Art Museum has decided to sell some works from its collection in order to raise the funds necessary to refurbish its galleries. Although this may seem like a drastic remedy the curator had long maintained that among the paintings that late Ms Fernando collected for the museum were several unsuccessful immature works by Rembrandt and Picasso that should be sold because they are of inferior quality and so add nothing to the overall quality of the museum's collection. Hence, the boards action will not detract from the museum's collection.
The conclusion drawn depends on which one of the following assumption?
A. Art speculators are unable to distinguish an inferior painting by Picasso from a masterpiece by him.
B. All of the paintings that the board of trustee sells will be among those that the curator recommends selling.
C. All of the paintings by Rembrandt and Picasso that are owned by the Fernando Art Museum were purchased by Ms Fernando hreself.
D. Only an avid collector of paintings by Rembrandt will be willing to pay a high price for early works by this artist.
E. A great work of art can be truly appreciated only if it is displayed in a carefully designed and well maintained gallery.

C. The immature works by Rembrandt and Picasso that were purchased by Ms Fedrici were at that time thought by some critics to be unimportant juvenile works.
D. Those people who speculate in art by purchasing artworks merely to sell them at much higher prices welcome inflation in the art market, but curators of art museum regret the inflation in the art market.
E. The best work of a great artist demands much higher prices in the art market than the worst work of that same artist.

The case of the French revolution is typically is regarded as the best evidence for the claim that societies can reap more benefit than harm from a revolution.
