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: Singapore did not have a native population in the true sense of the word as the population became dominated numerically by three main groups of immigrants after the British founded Singapore as a free port in the 19th century. It was estimated that when Raffles arrived in Singapore in January 1819, Singapore had about 120 Malays, 30 Chinese and some local tribes (the Orang Laut) under the rule of the Temenggung. Around 100 of these Malays had originally moved to Singapore from Johor in 1811 led by the Temenggung. Another estimate put the total population of the whole of Singapore at 1,000, mostly of various local tribes. Early census figures of Singapore show a long period of influx of migrant workers into the country, initially mostly Malays, quickly followed by the Chinese. By 1821, the population was estimated to have increased to 4,724 Malays and 1,150 Chinese. In the first census of 1824, 6,505 out of the 10,683 total were Malays and Bugis, constituting over 60% of the population. Large number of Chinese migrants started to enter Singapore just months after it became a British settlement, and they were predominantly male. In 1826, official census figures give a total population of 13,750, with 6,088 Chinese, 4,790 Malays, 1,242 Bugis, 1,021 Indians from Bengal (244) and the Coromandel Coast (777), smaller number of Javanese people (267), Europeans (87) and other peoples. The population total of Singapore increased to 16,000 in 1829, 26,000 five years later. By 1836, the Chinese at 13,749 had become the most populous ethnic group, overtaking the broad Malay grouping (12,538, including other groups such as the Bugis, Javanese, and Balinese). By the beginning of 1850, the population had reached 60,000, 24,790 of them Chinese.
Question: In what year did the Chinese population of Singapore surpass the Malay population?

SOLUTION: date

PROBLEM: Passage: Still looking for a win the Bills played on home ground for an AFC duel with the Jaguars. In the first quarter the Bills took the lead as QB Ryan Fitzpatrick made a 45-yard TD pass to WR Lee Evans; followed by kicker Rian Lindell making a 29-yard field goal. The Jaguars replied with kicker Josh Scobee nailing a 49-yard field goal, but in the second quarter the lead had expanded again with Lindell's 22-yard field goal. After that, the Jaguars rallied with Scobee getting another 49-yard field goal, then QB David Garrard made a 1-yard TD pass to TE Marcedes Lewis; followed in the third quarter by Garrard again finding Lewis on a 27-yard TD pass. Buffalo re-tied the game with Fitzpatrick completing a 5-yard TD pass to WR Steve Johnson, but the Jaguars pulled away with Garrard making a 7-yard TD pass to WR Mike Sims-Walker, followed in the fourth quarter by Scobee making a 34, 40 and a 46-yard field goal. Buffalo tried to tie the game with Fitzpatrick making a 7-yard TD pass to Johnson, but with a failed 2-point conversion, it became a 2-possession game which in turn became very difficult for Buffalo to recover. With the loss, Buffalo entered their bye week with their first 0-5 start since 1985.
Question: Who made the third longest field goal?

SOLUTION: span

PROBLEM: Passage: The start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland; the United Kingdom and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously, and the two wars merged in 1941. This article uses the conventional dating. Other starting dates sometimes used for World WarII include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939. The exact date of the war's end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945 , rather than the formal surrender of Japan, which was on 2 September 1945 that officially ended the war in Asia. A peace treaty with Japan was signed in 1951. A treaty regarding Germany's future allowed the reunification of East and West Germany to take place in 1990 and resolved most post-World War II issues. A formal peace treaty between Japan and the USSR had never been signed.
Question: What was the date that the United Kingdom and France declared war on Germany?

SOLUTION:
date
