Input: The organisers estimated that about 15,000 volunteers are needed to successfully host the games. Volunteer recruitment began in late 2013, and by February 2014, about 5,000 volunteers have signed up. This number swelled to over 17,000 by February 2015, and a volunteers night event was held at Universal Studios Singapore to launch the sports volunteers brand name as "Team Nila" and to thank the volunteers who have signed up with free shows at the venue. Amongst the pool of 17,000 volunteers, 35% came from the community, while 65% were from corporations in support of the games.

Question: How many volunteers were added from February 2014 to February 2015?


Input: 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?


Input: Worldwide sales of hybrid vehicles produced by Toyota reached 1 million vehicles by May 31, 2007, and the 2 million mark was reached by August 2009, with hybrids sold in 50 countries. The 5 million hybrid sales milestone was reached in March 2013. During 2012, Toyota and Lexus hybrid models sold more than 1 million units a year for the first time, with 1.219 million units sold. During 2013, TMC sold 1.279 million units, and the 6 million sales milestone was achieved in December 2013, just nine months after its latest million unit milestone. The 7 million sales mark was reached in September 2014, again, selling one million hybrids in nine months, and the 8 million sales milestone was achieved in July 2015, just 10 months after the previous million-unit milestone. The 9 million sales mark was reached in April 2016, again, selling one million hybrids in just nine months, and the 10 million milestone in January 2017, one more time nine months later. Toyota estimates that up to January 31, 2017, its hybrids have saved about 7.66 billion U.S. gallons of gasoline (29 billion liters) compared to the amount used by gasoline-powered vehicles of similar size, and have emitted approximately 77 million fewer tons of CO2 emissions than would have been emitted by gasoline-powered vehicles of similar size and driving performance.

Question: How many years did it take Toyota to go from 1 millions hybrids sold to 2 million?


Input: Coming off their season-opening win over the defending Super Bowl champion Ravens, the Broncos traveled to East Rutherford, New Jersey, for an interconference duel against the New York Giants at MetLife Stadium. This was the third match-up between brothers Peyton Manning (Broncos) and Eli Manning (Giants), with Peyton Manning winning the previous two match-ups as a member of the Indianapolis Colts &#8212; 2006 and 2010. The Giants grabbed the lead midway through the first quarter, with a 36-yard field goal by placekicker Josh Brown. In the second quarter, a 20-yard touchdown run by running back Knowshon Moreno gave the Broncos the lead. Two field goals by Brown &#8212; from 24 and 41 yards &#8212; gave the Giants a 9-7 lead. The Broncos re-claimed the lead just before halftime, with placekicker Matt Prater nailing a 42-yard field goal. The Broncos increased their lead in the third quarter, with quarterback Peyton Manning connecting on a 2-yard touchdown pass to wide receiver Wes Welker. The Giants responded, with running back Brandon Jacobs rushing for a 1-yard touchdown to pull the Giants to within 17-16 with three minutes remaining in the third quarter. However, the Broncos would seize control of the game with 21 unanswered points, beginning with a 25-yard touchdown run by Moreno, followed in the fourth quarter by an 11-yard touchdown pass from Peyton Manning to tight end Julius Thomas, and return specialist Trindon Holliday returning a punt 81 yards for a touchdown. The Giants tried to rally, with quarterback Eli Manning throwing a 23-yard touchdown pass to running back Da'Rel Scott with four minutes remaining in the fourth quarter, but a 47-yard field goal by Prater put the game out of reach. Peyton Manning improved his head-to-head record against Eli Manning to 3-0. Offensive tackle Ryan Clady suffered a Lisfranc fracture in his foot late in the fourth quarter, and was placed on injured reserve three days later (September 18).

Question:
How many field goals did Brown kick?
