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.

[Q]: Passage: While Ava had its hands full with the Manipuri raids in Upper Burma, a rebellion broke out at Pegu in November 1740. Ethnic Mon officials selected Smim Htaw Buddhaketi, a cousin of the king at Ava, as their king. The court at Pegu consolidated its hold in Lower Burma. Starting in 1742, Pegu, with renegade Dutch and Portuguese musketeers, began its annual raids of the upcountry. Because of the Manipuri threat, Ava could only send small armies to the south in 1743 and 1744, neither of which made any mark. The war "carried on languidly", with neither side achieving any lasting advantage until 1747. In December 1747, Binnya Dala came to power in Pegu, and the new king was determined to finish the war. He was not satisfied to gain independence for Lower Burma itself but determined to make Upper Burma its tributary. He stopped the annual raids and began planning for a decisive invasion. He sought and received French East India Company's support in firearms. Alarmed, Ava too sought support from China but no help materialised. In November 1751, Pegu launched a full-scale invasion by land and by river with a total strength of 30,000. Ava had prepared an extensive defensive line around Avaa riverside fort at Sinbyukyun on the Irrawaddy, and a series of forts at Sintgaing, Tada-U and Pinya en route to Ava. By mid-January, the invasion forces had overcome Ava's defences, and laid siege to the city. On 21 March 1752, the invaders broke through the city's outer walls. Two days later, they breached the inner walls and took the city. The 266-year-old Toungoo Dynasty had fallen.
Question: When did the invaders breach the inner walls and take the city?
[A]: date

[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?
[A]: date

[Q]: Passage: In the United States vitamin E supplement use by female health professionals was 16.1% in 1986, 46.2% in 1998, 44.3% in 2002, but decreased to 19.8% in 2006. Similarly, for male health professionals, rates for same years were 18.9%, 52.0%, 49.4% and 24.5%. The authors theorized that declining use in these populations may have due to publications of studies that showed either no benefits or negative consequences from vitamin E supplements. Within the US military services, vitamin prescriptions written for active, reserve and retired military, and their dependents, were tracked over years 2007-2011. Vitamin E prescriptions decreased by 53% while vitamin C remained constant and vitamin D increased by 454%. A report on vitamin E sales volume in the US documented a 50% decrease between 2000 and 2006, with a cause attributed to a meta-analysis that had concluded that high-dosage vitamin E increased all-cause mortality.
Question: How many percent did Vitamin E use increase from 1986 to 1998?
[A]:
number
