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: Prague employs almost a fifth of the entire Czech workforce, and its wages are significantly above average (~+25%). In December 2015, average salaries available in Prague reached 35,853 CZK, an annual increase of 3.4%, which was nevertheless lower than national increase of 3.9% both in nominal and real terms. (Inflation in Prague was 0.5% in December, compared with 0.1% nationally.) Since 1990, the citys economic structure has shifted from industrial to service-oriented. Industry is present in sectors such as pharmaceuticals, printing, food processing, manufacture of transport equipment, computer technology and electrical engineering. In the service sector, financial and commercial services, trade, restaurants, hospitality and public administration are the most significant. Service (economics) account for around 80 percent of employment. There are 800,000 employees in Prague, including 120,000 commuters. The number of (legally registered) foreign residents in Prague has been increasing in spite of the countrys economic downturn. As of March 2010, 148,035 foreign workers were reported to be living in the city making up about 18 percent of the workforce, up from 131,132 in 2008. Approximately one-fifth of all investment in the Czech Republic takes place in the city.
Question: Which year were there more foreign workers reported living in Prague, 2008 or 2010?

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?

Passage: An Italian Post Office opened on September 11, 1923 in Corfu, issuing a set of 8 Italian stamps overprinted "CORFU" which were placed on sale on the 20th. Three additional stamps overprinted in Greek currency arrived on 24th. The third stamp was 2.40 drachma on 1 lire. The Post Office closed at midday on 26 September 1923, only remaining open to dispatch the morning mail. The office had been open for 15 days. Three further values arrived on the day the Post Office closed, and were never issued. They eventually became available for sale at the postal ministry in Rome. Many used copies of these stamps have forged postmarks, but it is known that the Corfu cancel was applied to hundreds of stamps before the Post Office closed.
Question: When did three further values arrive, that were never issued?
