A、The true value of Pablo Picasso. B、The rare work discovered by an Indiana museum. C、The way to keep a rare work by Pablo Picas

W:(13)Have you heard that an art museum in Indiana has recently discovered a rare work by Pablo Picasso?
M: Really? How long has the work been stored?
W: It is reported that it’s been sitting in storage for almost half a century.
M: It must be valuable. How much does it cost?
W:(14)The Picasso could be worth up to four times the value of the museum’s entire collection.
M:(14)I think it’s so much of a good thing, in fact, that the museum can’t afford to keep it.
W: You’re right. Since the discovery in February, there has been a sea of assessments and meetings with the board of administrators and museum members.
M: What conclusion did they reach?
W: They discovered that the very value and rarity of the piece made it impossible for the natural forces to keep it.
M: So what would they do with the Picasso?
W:(15)The board voted this month to sell the work.
M: Well, this is a very difficult decision for the museum’s board of administrators.
W: Yes.(15)The Picasso might be in the $ 30 million to $40 million range which I think is probably a fair assessment.
M: And that’s precisely why the museum can’t keep it. (14)Here, where there is only one guard on duty in the art gallery, it would be nearly impossible to provide enough security.
W: That’s one of the reasons actually.
