Question: What was the full name of the music group that Dr. Dre and DJ Yella were a member of? Passage 1:Ušeničnik was born in the village of Poljane near the Upper Carniolan town of Škofja Loka, in what was then the Austro-Hungarian Empire (now in Slovenia). He studied theology at the Pontifical Gregorian University in Rome. In 1897, he became a professor at the Theological Seminary in Ljubljana. In 1919, he became a professor at the Faculty of Theology at the University of Ljubljana, where he taught philosophy. In 1922 and 1923, he served as the fourth chancellor of the University of Ljubljana. In 1937, he became a member of the Pontifical Academy of St. Thomas Aquinas and in 1938 one of the founding members of the Academy of Sciences and Arts in Ljubljana (later renamed the Slovenian Academy of Sciences and Arts). In 1948, he was expelled from the academy by the new communist regime. His membership was reinstated in 1996 after the collapse of communism.
 Passage 2:The video begins with an introduction of Dr. Dre's music career, such as when he and fellow N.W.A member DJ Yella were in the 1980s funk group World Class Wreckin' Cru. There are also scenes of Dr. Dre and his family, such as him hugging his daughter and son and getting married. There are also snippets from past music videos. It includes many rappers such as Eazy-E, 2Pac, The D.O.C, Snoop Dogg, Warren G, Eminem, Xzibit and all the rest of the members from N.W.A. The video then features Dr. Dre driving down Pacific Coast Highway in a Ferrari 360, with flashbacks of his life, crashing his car and the last thing heard was his daughter say "Good night Daddy." Then he is transported to a medical facility. The date at the beginning of the video is February 18, 2001 (his 36th birthday). They fast-forward to present day ten years later, where he has been hospitalized and is on life support. The Marin County Civic Center stands in for the medical facility. Eminem raps next to him as he is floating in an isolation tank, during which the figure of the Pythia (played by Canadian actress Estella Warren) is singing as a hologram behind and over Dre, mouthing the words to Skylar Grey's vocal part in the song. Skylar Grey herself appears as one of the doctors in the video, but never actually appears singing her part. Dre eventually wakes up and goes through rehab, and the video ends with him standing next to the grave of Eazy-E, a rapper who had launched Dre's music career by founding N.W.A and was also a member along with Ice Cube, MC Ren and DJ Yella. A ticking clock is heard midway through the video. The music video received complaints of being an "act of advertising" for a variety of product placements, such as Ferrari, G-Shock, HP, Gatorade, and Dr. Dre's signature headphones, Beats by Dr. Dre.
 Passage 3:The Action of 22 August 1917, took place in the First World War, in the Ypres Salient on the Western Front during the Third Battle of Ypres. The engagement was fought by the Fifth Army of the British Expeditionary Force and the German 4th Army. During the Battle of Langemarck (16–18 August), the British had advanced north of the village but had been defeated further south and failed to capture the , the third German defensive position. At a conference with the Fifth Army corps commanders on 17 August, Gough arranged for local attacks to gain jumping-off positions for another general attack on 25 August. At the Action of the Cockcroft on 19 August, XVIII Corps and the 1st Tank Brigade had captured five fortified farms and strongpoints for a fraction of the casualties of a conventional attack.
