The Board of Trustees of the Federici Art Museum has decided to sell some works from its collection in order to raise the funds necessary to refurbish its galleries.
Conclusion (Hence)
The board's action (selling some works from the collection to raise refurbishing funds) will not detract from the quality of the museum's collection.
Intermediate Conclusion (so)
The early works of Renoir / Cezanne that would get sold add nothing to the overall quality of the museum's collection.
Evidence
They are unsuccessful immature works of inferior quality.
Evaluate

Hmm, how can early crappy paintings add value? - Maybe they allow the museum to say "we have a complete set", which is something other museum's can't say. - Maybe Renoir and Cezanne reference these early works or build off them in some way in their later works, so if we didn't have the crappy early ones it would be harder to fully grasp the significance of the later ones.
Goal
Find some answer that allows us to say
