Q: Passage: Following the withdrawal of the SNA, the WSLF continued their insurgency. By May 1980, the rebels, with the assistance of a small number of SNA soldiers who continued to help the guerrilla war, controlled a substantial region of the Ogaden. However, by 1981 the insurgents were reduced to sporadic hit-and-run attacks and were finally defeated. In addition, the WSLF and SALF were significantly weakened after the Ogaden War. The former was practically defunct by the late 1980s, with its splinter group, the Ogaden National Liberation Front  operating from headquarters in Kuwait. Even though elements of the ONLF would later manage to slip back into the Ogaden, their actions had little impact. For the Barre regime, the invasion was perhaps the greatest strategic blunder since independence, and it weakened the military. Almost one-third of the regular SNA soldiers, three-eighths of the armored units and half of the Somali Air Force  were lost. The weakness of the Barre administration led it to effectively abandon the dream of a unified Greater Somalia. The failure of the war aggravated discontent with the Barre regime; the first organized opposition group, the Somali Salvation Democratic Front , was formed by army officers in 1979. The United States adopted Somalia as a Cold War ally from the late 1970s to 1988 in exchange for use of Somali bases, and a way to exert influence upon the region. A second armed clash in 1988 was resolved when the two countries agreed to withdraw their militaries from the border.
Question: When did Somalia and the US stop being allies?

Q: Passage: In the 2013–14 NBA season, the Spurs once again swept the Mavs in the regular season, giving them nine straight victories. In addition, an overtime loss to the Memphis Grizzlies on April 16, 2014 ensured that the Mavericks would face the Spurs once again in the 2014 NBA Playoffs, where the Mavs would be the eighth seed and San Antonio the first. In Game 1 in San Antonio, the game was relatively close. Dallas managed to reach an 81-71 lead in the fourth quarter, but the Spurs rallied back and took Game 1 at home, 85-90. However, the Mavs managed to force 22 turnovers in Game 2 to rout the Spurs 113-92, splitting the first two games before the series went to Dallas. In Game 3, Manu Ginóbili managed to hit a shot that put the Spurs up 108-106 with 1.7 left, but a buzzer beater by Vince Carter gave the Mavs the victory, putting them up 2-1 in the series. The Spurs took Game 4 in Dallas 93-89 and later Game 5 at home 109-103, giving them a 3-2 lead. Luckily, the Mavs avoided elimination in Game 6 at home by rallying in the fourth quarter, winning 111-113. The Spurs won game 7 119–96, eliminating the Mavericks in the first round.

Q: Passage: In 1960 Random House acquired Alfred A. Knopf. It is believed that the decision to sell was prompted by Alfred A. Knopf, Jr., leaving Knopf to found his own book company, Atheneum Books in 1959. Since its founding, Knopf has paid close attention to design and typography, employing notable designers and typographers including William Addison Dwiggins, Harry Ford, Steven Heller, Chip Kidd, Lorraine Louie, Bruce Rogers, Rudolf Ruzicka, and Beatrice Warde. Knopf books conclude with an unnumbered page titled "A Note on the Type", which describes the history of the typeface used for the book. In addition, Knopf books date the year of the book's current printing on the title page. Knopf published textbooks until 1988, when Random House's schools and colleges division was sold to McGraw-Hill. In 1991, Knopf revived the "Everyman's Library" series, originally published in England in the early 20th century. This series consists of classics of world literature in affordable hardcover editions. The series has grown over the years to include lines of Children's Classics and Pocket Poets. Random House was acquired by Bertelsmann in 1998. In late 2008 and early 2009, the Knopf Publishing Group merged with Doubleday to form the Knopf Doubleday Publishing Group. Random House has been owned since its 2013 merger of Penguin Group by Penguin Random House, a joint venture between Bertelsmann  and Pearson PLC . Many of Knopf's hardcover books are published later as Vintage paperbacks. Vintage Books is a sister imprint of Random House. In 2015, Knopf celebrated its 100th Anniversary by publishing a commemorative book, Alfred A. Knopf, 1915-2015: A Century of Publishing.
