Directions: Select the most appropriate filler(s) for the blank(s) such that the sentence makes coherent sense.

New York's Metropolitan Museum of Art owes much of its collection to the ________ of private collectors who willed their estates to the museum.

“Owes” and “willed” are the clue words in this sentence. Private collectors of New York had a longing for art that they willed their estates to the museum. Of all these options, yen (craving, longing) fits our prediction, hence replaces the blank. “Entreat” is an expression of desire, hence it would not be suitable. Hence, (1) is the answer.
