Question: In what modern day countries did the band of nomads who visited the Hami Desert live? Passage:Beyond an occasional visit from a band of nomad Mongols, this region of the Pe-shan swelling is entirely uninhabited. And yet it was from this region, according to Grigory Grum-Grshimailo (1889-1890 explorer), that the Yue-chi (Yuezhi), a nomadic people akin to the Tibetans, proceeded when, towards the middle of the 2nd century BC, they moved westwards and settled near Lake Issyk-kul; and from here proceeded also the Shanshani, or people who some two thousand years ago founded the state of Shanshan or Lofi-lan. The ruins of this town were discovered by Sven Hedin in the desert of Lop in 1901. Here, says the Russian explorer, the Huns gathered strength, as also did the Turks (Ch. Tukiu) in the 6th century, and the Uighur tribes and the rulers of the Tangut kingdom. But after Genghis Khan, in the 12th century, drew away the peoples of this region, and no others came to take their place, the country went out of cultivation and eventually became the barren desert it is now. During the Hun time, and probably into the Middle Ages, the present desert was a lush steppe grassland able to support sustainable seasonal nomadic horse husbandry on a large scale.

Question: What city was the game held where Beccacece's team beat O'Higgins 8-1? Passage:On 24 January, in his second league game since his debut for this competition at the bench (a 11 away draw with Deportes Antofagasta), Beccacece impressed following the team's 81 home thrash over O'Higgins at the Estadio Nacional. After of that great victory nevertheless the team reaped three draws and one loss against Palestino (21). During February's first days, the team was eliminated of the Copa Libertadores first stage by Uruguay's River Plate F.C., which was his first failure and it meant being the target of criticism from the press and the team's supporters. On 28 February, the 41 away victory over Cobresal would be a balm of the team's moment. Following a 00 draw with Union Espanola and two losses (31 with Universidad de Concepcion as local and 54 against Santiago Wanderers as visitors), he back to draw, now in the Chilean football derby with Colo-Colo, which was again a goalless where both teams were criticized for its game level. Finally, Beccacece would end in the tenth place with three wins, seven draws and five losses and his continuity was heavily questioned during the Copa America Centenario break.

Question: In what year did Jared Taylor found the American Renaissance? Passage:In February 2010, Breitbart received the Reed Irvine Accuracy in Media Award during the Conservative Political Action Conference in Washington, D.C. During his acceptance speech, he responded directly to accusations by The New York Times reporter Kate Zernike that Jason Mattera, a young conservative activist, had been using "racial tones" in his allusions to President Barack Obama, and had spoken in a "Chris Rock voice". From the podium, Breitbart called Zernike "a despicable human being" for having made such allegations about what, according to him, was just Mattera's Brooklyn accent. At the same conference, Breitbart was also filmed saying to journalist Max Blumenthal that he found him to be "a jerk" and "a despicable human being" over a blog entry in which Blumenthal accused Breitbart of employing a racist. Blumenthal was referring to James O'Keefe over his having attended a Georgetown Law Center discussion on race featuring Kevin Martin, John Derbyshire, and Jared Taylor, the last of whom founded American Renaissance, an online magazine widely considered white supremacist. Neither O'Keefe nor Breitbart endorsed Taylor's views.
