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.

Question: Who was younger the year Gorelick earned her M.A., Raphael Soyer or Moses Soyer? Passage:Born Shirley Fishman in Brooklyn, New York, she attended Abraham Lincoln High School. Her teacher, Leon Friend, arranged for guest lectures by commercial and fine artists. Shirley Fishman had the opportunity to study with three of them: Chaim Gross, Moses Soyer, and Raphael Soyer. Gross influenced her early sculptural work, which features squat figures with thick limbs. While attending Brooklyn College, where she earned her B.A. in 1944, she met Leonard Gorelick (19222011), a fellow student. They married in 1944 and shared an enthusiasm for art and culture. Leonard Gorelick was an orthodontist and later a collector of cylinder seals. He combined his interests by investigating the authenticity of cylinder seals through the use of dental technology, especially electronmicroscopy. Shirley Gorelick earned an M.A. at Teachers College, Columbia University in 1947. That year, she studied for several weeks with Hans Hofmann in Provincetown. For a short time in the late 1950s, she was a student of the painter Betty Holliday and, in the early 1960s, learned printmaking in the Long Island studio of Ruth Leaf.

Question: How many times did Steffi Graf win the Australian Open? Passage:Graf lost an Australian Open quarterfinal to Jana Novotna, the first time she did not reach the semifinals of a Grand Slam singles tournament since the 1986 French Open. She then lost to Sabatini in her next three tournaments before winning the U.S. Hardcourt Championships in San Antonio, beating Monica Seles in the final. After losing a fifth straight time to Sabatini in Amelia Island, Florida, Graf again defeated Seles in the Hamburg final. Following her tournament victory in German Open in Berlin, Graf suffered one of the worst defeats of her career in a French Open semifinal where she won only two games against Sanchez Vicario and lost her first 60 set since 1984. At Wimbledon, however, Graf captured her third women's crown, this time at Sabatini's expense. Sabatini served for the match twice, and was two points away from her first Wimbledon title. After breaking Sabatini's serve to even the third set at 66, Graf defeated Sabatini by winning the next two games to take the match 64, 36, 86. Martina Navratilova then defeated Graf 76, 67, 64 in a US Open semifinal, the first time she had beaten Graf in four years. Graf then won in Leipzig, with her 500th career victory coming in a quarterfinal against Judith Wiesner. After winning two more indoor tournaments at Zurich and Brighton, she failed once again in the Virginia Slims Championships, losing her quarterfinal to Novotna. Soon after, she split with her long-time coach, Pavel Slozil.
