Question: Which of the three singles Tamia was nominated for Grammys for in the 40th Annual Grammy Awards had the most sales? Passage:In 1994, Tamia signed her first recording deal with Warner Bros. Records and collaborated with veteran producer Quincy Jones on his album Q's Jook Joint (1995). Their output, the singles "You Put a Move on My Heart" and "Slow Jams", as well as "Missing You", a song Tamia recorded with Brandy, Gladys Knight, and Chaka Khan for the soundtrack of the 1996 motion picture Set It Off, each earned her nominations at the 40th Annual Grammy Awards. She later co-signed with Jones's Qwest Records label, a joint venture with Warner Bros., on which her self-titled debut album was released in 1998. Upon its release, Tamia received a mixed to positive reception by critics and garnered the singer two Juno Award nominations for Best New Solo Artist and R&B/Soul Recording of the Year at the 1999 award ceremony. In addition, it peaked at number sixty-seven on the Billboard 200 chart, selling 416,000 copies in the United States, and was eventually certified gold in Japan for 100,000 copies shipped to stores.

Question: How old was Derow's teacher and lasting influence at Oxford when Derow graduated from Oxford? Passage:Born in Newport, Rhode Island, Derow obtained his secondary education at The Roxbury Latin School in West Roxbury, Massachusetts. After an A.B. degree at Amherst (with Peter K. Marshall), he read for Greats as a second B.A. degree at Oxford in 1965–1967, achieving a First. At Oxford he was taught by, among others, W. G. (George) Forrest, who was a lasting influence. He completed a Ph.D. at Princeton on 'Rome and the Greek world from the earliest contacts to the end of the first Illyrian war', for which Professor J. V. A. Fine was his Advisor; in the preface to that work, he acknowledges the additional inspiration he had drawn from T. J. Luce and the historian and epigrapher C. Bradford Welles. After a spell of teaching at the University of Toronto, he returned to succeed Forrest at Wadham in 1977 when the latter was elected to the Wykeham Professorship of Ancient History at New College. In 2002–2005 Derow was also Director of Graduate Studies in ancient history for the Oxford Faculty of Classics.

Question: In what year was the lower jaw of an Anachlysicitis found in the Vilavieja Formation? Passage:Anachlysictis gracilis is an extinct carnivorous mammal belonging to the group Sparassodonta, which were metatherians (a group including marsupials and their close relatives) that inhabited South America during the Cenozoic. Unlike other remains assigned to the family Thylacosmilidae (a group of metatherian predators equipped with "saber teeth") that had been found previously, Anachlysictis is the first record of such borhyaenoids in northern South America, and also most primitive and ancient in the family (in fact, is the first confirmed record that did not belong to the genus Thylacosmilus, until the official publication of Patagosmilus in 2010). This species was found in the Villavieja Formation in the area of La Venta in Colombia, a famous fossil deposit in the Middle Miocene (Laventan; 13.8-11.8 million years ago), based on fragments that include a front portion of the lower jaw, with an incipient molar tooth and a piece of carnassial from the front of the maxilla.
