Q: 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.

Q: Passage: The Victor Emmanuel Railway, which included both the CulozModane railway across Savoy and the TurinModane railway across Piedmont, was largely built in the 1850s by the Kingdom of Sardinia and named after its king, Victor Emmanuel II. Until 1860 Sardinia included both Savoy and Piedmont. The line from Turin to Susa was inaugurated on 22 May 1854. Work on the tunnel began on 31 August 1857 and was completed in September 1871. Work had begun on the line between Bussoleno and Bardonecchia in 1867 and was completed at the same time as the tunnel. The tunnel and line were opened on 16 October 1871. By that time, the Savoy side of the tunnel had become part of France. The decision of the engineers to begin the line at Bussoleno in order to reduce the gradient on the climb near Meana was much criticized for bypassing the city of Susa, which was left isolated on a short branch line. The opening of the tunnel also led to the closure of the short-lived Mont Cenis Pass Railway. In 1865 the line became part of the network of the Societa per le strade ferrate dell'Alta Italia (Upper Italian Railways, SFAI) on its foundation in 1865 and was taken over by the Rete Mediterranea (Mediterranean Network) in 1885. Finally in 1905 it became part of the Ferrovie dello Stato network.

Q: Passage: Initially intending to go into medicine, Smith became interested in biology and organic chemistry during his second year at Columbia University. He earned a B.S. in 1931 and stayed at Columbia to study photosynthesis under Selig Hecht, completing a Ph.D. in biophysics in 1936. In 1938, he went to Cambridge University on a Guggenheim Fellowship to work with David Keilin on the chlorophyll-protein complex. Upon returning to the U.S. during World War II, he took a position at Yale University's Connecticut Agricultural Experiment Station to work with Hubert Bradford Vickery. He joined the lab of eminent protein chemist Max Bergmann at the Rockefeller Institute in 1940, where he worked with a number of important biochemists and began a significant line of research on the intestinal enzyme erepsin.
