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.

Passage: The Rams' fourth game was played at home in an NFC west rivalry match against the Seattle Seahawks. In the first quarter the Rams took the early lead as QB Sam Bradford completed a 15-yard TD pass to WR Brandon Gibson. The Seahawks cut the lead with kicker Olindo Mare nailing a 22-yard field goal, but the Rams increased their lead when kicker Josh Brown made a 30-yard field goal, followed in the 3rd quarter by Bradford completing a 21-yard TD pass to RB Kenneth Darby. Then Josh Brown made a 31-yard field goal. With the victory, the Rams improved to 2-2, thus successfully improving on their previous season. The win also snapped a 10-game regular season losing streak to the Seahawks.

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?

Passage: In order to regain control of the custom duties, the emperor John VI Kantakouzenos made preparations to lower Constantinople's duties and most tariffs to undercut the Genoese in Galata. Still recovering from the civil war of 1341-1347, the emperor, with great difficulty, raised 50,000 hyperpyra from private sources for a shipbuilding program for the expected war to come. When the tariffs and custom duties were finally lowered, merchant shipping coming through the strait bypassed Genoese Galata and diverted their ships across the Golden Horn to Byzantine Constantinople. The Genoese, financially hard-hit from this policy, declared war on the Empire, and in August 1348, a flotilla of ships sailed across the Horn and attacked the Byzantine fleet; despite their large scale preparations, the Byzantine fleet was destroyed by early 1349. The Byzantines retaliated by burning wharves and warehouses along the shore and catapulted stones and burning bales of hay into Galata, setting major parts of the city on fire. After several weeks of fighting, plenipotentiaries from Genoa came and negotiated a peace agreement. The Genoese agreed to pay a war indemnity of 100,000 hyperpyra and evacuated the land behind Galata which they illegally occupied; last, they promised never to attack Constantinople. In return the Byzantines surrendered nothing, but the Genoese custom duties remained in effect.
