TASK DEFINITION: This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.
PROBLEM: 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?

SOLUTION: date

PROBLEM: Passage: After a tough home loss to the Texans, the Raiders traveled east to take on the Patriots.  The Raiders took an early lead when Sebastian Janikowski kicked a 49-yard field goal for a 3-0 game and the only score of the first quarter.  The Patriots took the lead in the 2nd quarter when Tom Brady found Rob Gronkowski on a 6-yard touchdown pass for a 7-3 game followed up by Stephen Gostowski kicking a 21-yard field goal for a 10-3 lead at halftime.  In the 3rd quarter, the Raiders went back to work as Janikowski nailed 2 field goals from 37 and 47 yards out coming within 4, 10-6 and then within 1, 10-9.  However, in the 4th quarter, the Patriots were able to eventually win the game when Gostkowski kicked 2 field goals from 20 and 36 yards out first for a 13-9 and the eventual final score of 16-9.  The Raiders were held without a touchdown in a single game for the first time since their 17-6 loss to the Panthers in 2012.
Question: What team was behind after the first quarter?

SOLUTION: span

PROBLEM: Passage: The Front refused to officially disclose the number of members that it had. Thurlow suggested that "the most reliable estimates" were those produced by the anti-fascist investigatory magazine Searchlight (magazine). Following its establishment, the NF claimed to have 4000 members in 1968, and in February 1974 a branch chairman claimed that it had 20,000 members. Fielding suggested that it probably had about 21,000 members in early 1975, of whom 6,000 to 8,000 were "paper members" who had not renewed their membership subscriptions but not officially terminated their membership. Searchlight claimed that from its origins with 4,000 members in 1968, the party reached a peak membership of 17,500 in 1972, which had declined to 10,000 in 1979, to 3,148 in 1984, and to 1,000 in January 1985. An estimate of party membership in 1989 put adherents of the Flag Group at about 3,000 and of the Strasserite faction at about 600. Thurlow noted that even at its peak in the 1970s, the Fronts membership was still only half the size of that of the BUF during its 1930s heyday.
Question: What year was the membership, according to the  of the Searchlight, for the Front closest to the membership total of the Flag Group in 1989?

SOLUTION:
date
