Quote:
The governing body of the Emily Schaeffer Museum has decided to sell some pieces from its collection in order to raise the funds necessary to refurbish its galleries. Although this may seem like a drastic measure, the curator had long maintained that among the paintings that the late Ms. Schaeffer 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 governing body's action will not diminish the quality of 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 governing body sells will be among those that the curator recommends selling.
C. All of the paintings by Rembrandt, and Picasso that are owned by the Emily Schaeffer Art Museum were purchased by Ms. Schaeffer herself.
D. Only an avid collector of paintings by Rembrandt would 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.
The assumption is one that NEEDS to be true for the argument to stand, or in other words, for the conclusion to be drawn from the premise. It may be a simple obvious universal statement, a missing link that connects the premise to the conclusion, or a statement ruling out a case that would falter the conclusion.
A popular way to think about a conclusion is to imagine a situation where the potential assumption is false and check the validity of the conclusion. Be careful about the little adjectives and adverbs limiting the scope of the argument.
Conclusion: the governing body's action will not diminish the quality of the museum's collectionQuote:
A. Art speculators are unable to distinguish an inferior painting by Picasso from a masterpiece by him.
The argument is clearly focussing on the actual quality of the collection. How speculators feel about that quality is irrelevant to the conclusion. Even if it was relevant, we don't NEED it to be true. - Rejected

B. All of the paintings that the governing body sells will be among those that the curator recommends selling.
'All' gets my attention immediately. Let's say there is a painting 'X' that is not part of the set recommended by the curator (making the statement in option B false). Since the curator's set includes all museum paintings that are of inferior quality, so 'X' is not a poor quality painting. Selling 'X' WILL diminish the quality of the collection, even if very slightly. More such paintings, the higher the loss of quality.
Option B stands since it needs to be true.
Quote:
C. All of the paintings by Rembrandt, and Picasso that are owned by the Emily Schaeffer Art Museum were purchased by Ms. Schaeffer herself.
Whether the paintings were sold to Mr. Schaeffer herself or someone else will not help us with the conclusion. Let's say these ones were sold to someone else, the argument may still stand.
Option C Rejected.
Quote:
D. Only an avid collector of paintings by Rembrandt would be willing to pay a high price for early works by this artist.
'Only' takes my attention here. Let's say a not-so-avid collector is willing to pay a higher price for early works. The argument may still stand.
Option D Rejected.

E. A great work of art can be truly appreciated only if it is displayed in a carefully designed and well-maintained gallery.
The argument is talking about the quality of the collection. This statement confuses one to think that the appreciation of art is equivalent to its quality. This would be another un-mentioned assumption, which is not be considered. Even with this un-mentioned assumption, this option doesn't go far.
Focus on 'only' again. Let's say a great work of art can be truly appreciated even if it was displayed in a low-maintained gallery. We still cannot say much about whether the quality of the collection is getting diminished since the quality can be maintained as long as the correct paintings are being sold.
Option E Rejected.
IMO Option B is correct.
