Input: Consider Input: Question: Who won the 2017 edition of the same award that Jean Hagen was nominated? Passage:The film was only a modest hit when first released. O'Connor won the Golden Globe Award for Best Actor Motion Picture Musical or Comedy, and Betty Comden and Adolph Green won the Writers Guild of America Award for their screenplay, while Jean Hagen was nominated for the Academy Award for Best Supporting Actress. However, it has since been accorded legendary status by contemporary critics, and is frequently regarded as the best film musical ever made, and the best film ever made in the "Freed Unit" at Metro-Goldwyn-Mayer. It topped the AFI's Greatest Movie Musicals list and is ranked as the fifth-greatest American motion picture of all time in its updated list of the greatest American films in 2007. In 1989, the United States Library of Congress selected the film for preservation in the National Film Registry.

Input: Consider Input: Question: How long was the painting a feature of the collection before being acquired by Catherine II of Russia? Passage:By 1627 the painting belonged to William Herbert, 3rd Earl of Pembroke (1580-1630), and was at Wilton House in Wiltshire. Either the 3rd or 4th earl presented it to King Charles I of England. After the English Civil War it was sold in one of the sales of the Royal Collection at Somerset House in London on 19 December 1651. Soon after it was in France. The painting was later a highlight of the Pierre Crozat collection which was acquired through Diderot's mediation by Catherine II of Russia in 1772. For a century and a half, the panel hung in the Imperial Hermitage Museum. It was one of the most popular paintings in the entire collection of the Tsars. In March 1931 it was part of the Soviet sale of Hermitage paintings, and bought by Andrew Mellon, as part of his founding donation to the National Gallery of Art in Washington D.C. This and other foundational artworks, including paintings by Jan van Eyck, Sandro Botticelli, and Titian, helped place the National Gallery among the most significant collections of Renaissance art.
