Problem: Utrecht:

Although there is some evidence of earlier inhabitation in the region of Utrecht, dating back to the Stone Age (app. 2200 BCE) and settling in the Bronze Age (app. 1800–800 BCE), the founding date of the city is usually related to the construction of a Roman fortification (castellum), probably built in around 50 CE. A series of such fortresses was built after the Roman emperor Claudius decided the empire should not expand north. To consolidate the border the limes Germanicus defense line was constructed  along the main branch of the river Rhine, which at that time flowed through a more northern bed compared to today (what is now the Kromme Rijn). These fortresses were designed to house a cohort of about 500 Roman soldiers. Near the fort settlements would grow housing artisans, traders and soldiers' wives and children.

How far back does evidence of inhabitation date back

A: inhabitation in the region of Utrecht, dating back to the Stone Age (app. 2200 BCE)


Problem: With increasing environmental concerns about synthetic coatings (such as PFOA) and the higher prices of hydrocarbon based petrochemicals, there is a focus on zein (corn protein) as a coating for paper in high grease applications such as popcorn bags.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Victoria's father was Prince Edward, Duke of Kent and Strathearn, the fourth son of the reigning King of the United Kingdom, George III. Until 1817, Edward's niece, Princess Charlotte of Wales, was the only legitimate grandchild of George III. Her death in 1817 precipitated a succession crisis that brought pressure on the Duke of Kent and his unmarried brothers to marry and have children. In 1818 he married Princess Victoria of Saxe-Coburg-Saalfeld, a widowed German princess with two children—Carl (1804–1856) and Feodora (1807–1872)—by her first marriage to the Prince of Leiningen. Her brother Leopold was Princess Charlotte's widower. The Duke and Duchess of Kent's only child, Victoria, was born at 4.15 a.m. on 24 May 1819 at Kensington Palace in London.
Who was the reigning King of the United Kingdom until 1871?
A: unanswerable


Context and question: Solar radiation is absorbed by the Earth's land surface, oceans – which cover about 71% of the globe – and atmosphere. Warm air containing evaporated water from the oceans rises, causing atmospheric circulation or convection. When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle. The latent heat of water condensation amplifies convection, producing atmospheric phenomena such as wind, cyclones and anti-cyclones. Sunlight absorbed by the oceans and land masses keeps the surface at an average temperature of 14 °C. By photosynthesis green plants convert solar energy into chemically stored energy, which produces food, wood and the biomass from which fossil fuels are derived.
How does the water vapor that rises in warm air turn into clouds?
Answer: When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds


Question: One way to divide hunter-gatherer groups is by their return systems. James Woodburn uses the categories "immediate return" hunter-gatherers for egalitarian and "delayed return" for nonegalitarian. Immediate return foragers consume their food within a day or two after they procure it. Delayed return foragers store the surplus food (Kelly, 31).
Is there an answer to this question: What is the only way to divide hunter-gatherer groups?

Answer: unanswerable


Articles 41 and 68 of the constitution empower the sovereign to withhold royal assent from bills adopted by the Legislative Assembly. In 2010, the kingdom moved towards greater democracy, with King George Tupou V saying that he would be guided by his prime minister in the exercising of his powers. Nonetheless, this does not preclude an independent royal decision to exercise a right of veto. In November 2011, the assembly adopted an Arms and Ammunitions (Amendment) Bill, which reduced the possible criminal sentences for the illicit possession of firearms. The bill was adopted by ten votes to eight. Two members of the assembly had recently been charged with the illicit possession of firearms. The Prime Minister, Lord Tuʻivakanō, voted in favour of the amendment. Members of the opposition denounced the bill and asked the King to veto it, which he did in December.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What bill was adopted by eight votes to ten?
Ah, so..
unanswerable
