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 the WSLF lose control over a substantial region of the Ogaden?
answer:
date


question:
Passage: A rejuvenated Nick Foles got his starting job back after being benched in favor of Case Keenum, who suffered a concussion after last week's loss in Baltimore. However, Foles' return was marred as he struggled to find open receivers and was picked off three times by the Bengals ranked defense. He also took hits throughout the game and he was sacked a few times. The only Rams score was a 5-yard run by Tavon Austin on a reverse play in the second quarter. St. Louis' defense was not a factor all game as they struggled to stop the high-powered Bengals offense led by quarterback Andy Dalton, and receivers A. J. Green, and Tyler Eifert, (the latter left the game with a stinger) who is leading the league in touchdown catches. With the loss, the Rams extended their losing streak to 4 games, making their record 4-7.
Question: Who did Keenum suffer his concussion playing against?
answer:
span


question:
Passage: Although the putsch has been named after Wolfgang Kapp, a 62-year-old nationalist East Prussian civil servant, who had been planning a coup against the republic for a while, it was instigated by the military; Kapp played a supporting role.:217:50 On 29 February 1920, the Defence Minister Noske ordered the disbandment of two of the most powerful Freikorps, the Marinebrigade Loewenfeld and Marinebrigade Ehrhardt. The latter numbered from 5,000-6,000 men and had been stationed at the Truppenübungsplatz Döberitz, near Berlin, since January 1920.:217 An elite force, it had been created from former Imperial Navy officers and NCOs, boosted later by Baltikumer . During the civil war in 1919, the brigade had seen action in Munich and Berlin. It was extremely opposed to the democratic government of Friedrich Ebert.:217 Its commander, Korvettenkapitän Hermann Ehrhardt, declared that the unit would refuse its dissolution.:51 On 1 March, it staged a parade without inviting Noske.:218 General Walther von Lüttwitz, in command of all the regular troops in and around Berlin , the highest ranking general in the army at the time and in command of many Freikorps, said at the parade that he would "not accept" the loss of such an important unit. Several of Lüttwitz' officers were horrified at this open rejection of the government's authority and tried to mediate, by setting up a meeting between Lüttwitz and the leaders of the two major right-wing parties. Lüttwitz listened to and remembered their ideas but was not dissuaded from his course of action.:218 Noske then removed the Marinebrigade from Lüttwitz' command and assigned it to the leadership of the Navy, hoping that they would disband the unit. Lüttwitz ignored the order but agreed to a meeting with President Ebert, suggested by his staff.
Question: Who commanded the Marinebrigade first, Lüttwitz or the  Navy?
answer:

span
