Problem: 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.

How many more volunteers signed up after the initial 5000 in February 2014?
Answer: 12000

Problem: In an attempt to break a three-game losing streak the Titans flew to Reliant Stadium for an AFC South rivalry match against the Texans. The Titans trailed throughout the game as QB Matt Schaub got a 1-yard TD pass to TE Joel Dreessen, followed by his 2-yard TD pass to WR Andre Johnson. The lead was increased when kicker Neil Rackers hit a 35 and a 33-yard field goal. With 7:53 remaining in the 4th quarter, an altercation between Texans WR Andre Johnson and Titans CB Cortland Finnegan broke out, causing both players to be ejected for the rest of the game. Both players' helmets were torn off, then punches were exchanged in return. Despite being ejected, they avoided suspension, but were each fined $25,000 for their actions. With the shut-out loss, not only did the Titans fall to 5-6, but this also became their 3rd straight season being shut out on the road.

How many total yards were Racker's field goals?
Answer: 68

Problem: According to Jean Ziegler , mortality due to malnutrition accounted for 58% of the total mortality in 2006: "In the world, approximately 62 millions people, all causes of death combined, die each year. In 2006, more than 36 million died of hunger or diseases due to deficiencies in micronutrients". Of the roughly 150,000 people who die each day across the globe, about two thirds—100,000 per day—die of age-related causes. In industrialized nations, the proportion is much higher, reaching 90%.

How many percent of the mortality rate in 2006 was not due to malnutrition?
Answer: 42

Problem: The Shang dynasty   or Yin dynasty , according to traditional historiography, ruled in the Yellow River valley in the second millennium BC, succeeding the Xia dynasty and followed by the Zhou dynasty.  The classic account of the Shang comes from texts such as the Classic of History, Bamboo Annals and Records of the Grand Historian.  According to the traditional chronology based upon calculations made approximately 2,000 years ago by Liu Xin, the Shang ruled from 1766 BC to 1122 BC, but according to the chronology based upon the "current text" of Bamboo Annals, they ruled from 1556 BC to 1046 BC. The Xia-Shang-Zhou Chronology Project dated them from c. 1600 BC to 1046 BC. At its peak 1122 BC it covered an area of 1,250,000 km2.

How many years do the Bamboo Annals and the Xia-Shang-Zhou Chronology Project differ by for the length of the Shang dynasty?
Answer:
4
