[Q]: 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.

[Q]: Question: Has the actor who was confirmed for a role in May of 2018 previously worked with the director of this film? Passage:On March 8, 2017, it was announced that 20th Century Fox had bought the spec script Bad Times at the El Royale, written by Drew Goddard, who would also direct and produce the film. On August 23, 2017, Chris Hemsworth and Jeff Bridges were cast in the 1960s-set film, to play two among the several characters who collide at the El Royale hotel, near California's Lake Tahoe. That same day, it was also reported that Tom Holland had passed on a role, and that Beyonce was being courted for the role of a Black vocalist. It was also revealed that main roles in the ensemble would include a vacuum cleaner salesman, two female criminals, a male cult leader, and a desk clerk. Later in August 2017, newcomer Cailee Spaeny was added to the cast to play an impressionable Southern girl brought to the hotel, while Cynthia Erivo was cast as the Black singer who finds herself in the wrong place at the wrong time. In January 2018, Dakota Johnson and Russell Crowe joined the cast (though Crowe did not appear in the film).

[Q]: Question: Which of Boyer's collaborators in 1977 completed their education first? Passage:Hebert Boyer was born in 1936 in Derry, corner of western Pennsylvania where railroads and mines were the destiny of most young men. He received his bachelor's degree in biology and chemistry from Saint Vincent College in Latrobe, Pennsylvania, in 1958. He married his wife Grace the following year. He received his PhD at the University of Pittsburgh in 1963 and participated as an activist in the civil rights movement. He spent three years in post-graduate work at Yale University in the laboratories of Professors Edward Adelberg and Bruce Carlton, then became an assistant professor at the University of California, San Francisco and a Professor of Biochemistry from 1976 to 1991, where he discovered that genes from bacteria could be combined with genes from eukaryotes. In 1977, Boyer's laboratory and collaborators Keiichi Itakura and Arthur Riggs at City of Hope National Medical Center described the first-ever synthesis and expression of a peptide-coding gene. In August 1978, he produced synthetic insulin using his new transgenic genetically modified bacteria, followed in 1979 by a growth hormone.
