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: Unemployment hovered at 8-10% after the start of the economic slowdown in 1999, above the 7% average for the 1990s. Unemployment finally dipped to 7.8% in 2006, and continued to fall in 2007, averaging 6.8% monthly (up to August). Wages have risen faster than inflation as a result of higher productivity, boosting national standard of living. The percentage of Chileans with household incomes below the poverty line - defined as twice the cost of satisfying a persons minimal nutritional needs - fell from 45.1% in 1987 to 11.7% in 2015, according to government polls. Critics in Chile, however, argue that poverty figures are considerably higher than those officially published; until 2016, the government defined the poverty line based on an outdated 1987 household consumption poll, instead of more recent polls from 1997 or 2007. According to critics who use data from the 1997 poll, the poverty rate goes up to 29%; a study published in 2017 claims that it reaches 26%. Using the relative yardstick favoured in many European countries, 27% of Chileans would be poor, according to Juan Carlos Feres of the ECLAC. Starting in 2016, a new Multidimensional Poverty Index is also used, which reached 20.9% using 2015 data.
Question: How many percent difference is there between the data in the 1997 poll of the poverty rate compared to the study published in 2017?
number

Passage: Salin turned out to be the last battle of the war. After the successive battlefield defeats, the bickering between the Confederation's two main powers broke out in full force. Sawlon II of Mohnyin, who had only grudgingly agreed to Hkonmaing's takeover of the Ava throne, blamed Hkonmaing for the defeats, and now planned to put Sithu Kyawhtin I of Salin on the Ava throne. In April/May 1545, Sawlon II sent Sithu Kyawhtin with an army , which went on to occupy Sagaing, the city directly across the Irrawaddy from Ava. During the rainy season, c. September 1545, Hkonmaing died, and was succeeded by his son Narapati III. The new king promptly sent a mission to Pegu to secure friendly relations in exchange for his recognition of the new de facto border between the two kingdoms. Tabinshwehti accepted the offer. Toungoo's decisive victory gave the upstart kingdom control of all of central Burma, and cemented its emergence as the largest polity in Burma since the fall of Pagan Empire in 1287. Indeed, "there was once more a king in Burma". In the following years, Ava and Mohnyin-backed Sagaing would be locked in a war until 1551, while an emboldened Toungoo would turn its attention to conquering Arakan in 1545-47, and Siam in 1547-49.
Question: What was the starting year for Toungoo to turn its attention to conquering Arakan?
