Input: Read this: Child labour is still common in many parts of the world. Estimates for child labour vary. It ranges between 250 and 304 million, if children aged 517 involved in any economic activity are counted. If light occasional work is excluded, ILO estimates there were 153 million child labourers aged 514 worldwide in 2008. This is about 20 million less than ILO estimate for child labourers in 2004. Some 60 percent of the child labour was involved in agricultural activities such as farming, dairy, fisheries and forestry. Another 25 percent of child labourers were in service activities such as retail, hawking goods, restaurants, load and transfer of goods, storage, picking and recycling trash, polishing shoes, domestic help, and other services. The remaining 15 percent laboured in assembly and manufacturing in informal economy, home-based enterprises, factories, mines, packaging salt, operating machinery, and such operations. Two out of three child workers work alongside their parents, in unpaid family work situations. Some children work as guides for tourists, sometimes combined with bringing in business for shops and restaurants. Child labour predominantly occurs in the rural areas (70%) and informal urban sector (26%).
Question: Some child work as guides for whom?

Output: tourists

QUES: The influence of Old Norse certainly helped move English from a synthetic language along the continuum to a more analytic word order, and Old Norse most likely made a greater impact on the English language than any other language. The eagerness of Vikings in the Danelaw to communicate with their southern Anglo-Saxon neighbors produced a friction that led to the erosion of the complicated inflectional word-endings. Simeon Potter notes: "No less far-reaching was the influence of Scandinavian upon the inflexional endings of English in hastening that wearing away and leveling of grammatical forms which gradually spread from north to south. It was, after all, a salutary influence. The gain was greater than the loss. There was a gain in directness, in clarity, and in strength."

What was the name of the area in England ruled by the Vikings?
What is the answer?
ANS: the Danelaw

QUES: The common features of passive solar architecture are orientation relative to the Sun, compact proportion (a low surface area to volume ratio), selective shading (overhangs) and thermal mass. When these features are tailored to the local climate and environment they can produce well-lit spaces that stay in a comfortable temperature range. Socrates' Megaron House is a classic example of passive solar design. The most recent approaches to solar design use computer modeling tying together solar lighting, heating and ventilation systems in an integrated solar design package. Active solar equipment such as pumps, fans and switchable windows can complement passive design and improve system performance.
What kind of equipment can improve system performance?

ANS: pumps, fans and switchable windows

A number of pubs claim to be the oldest surviving establishment in the United Kingdom, although in several cases original buildings have been demolished and replaced on the same site. Others are ancient buildings that saw uses other than as a pub during their history. Ye Olde Fighting Cocks in St Albans, Hertfordshire, holds the Guinness World Record for the oldest pub in England, as it is an 11th-century structure on an 8th-century site. Ye Olde Trip to Jerusalem in Nottingham is claimed to be the "oldest inn in England". It has a claimed date of 1189, based on the fact it is constructed on the site of the Nottingham Castle brewhouse; the present building dates from around 1650. Likewise, The Nags Head in Burntwood, Staffordshire only dates back to the 16th century, but there has been a pub on the site since at least 1086, as it is mentioned in the Domesday Book.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What pub holds the Guinness World Record as the oldest in England?
Ah, so.. Ye Olde Fighting Cocks

Question: Neptune's dark spots are thought to occur in the troposphere at lower altitudes than the brighter cloud features, so they appear as holes in the upper cloud decks. As they are stable features that can persist for several months, they are thought to be vortex structures. Often associated with dark spots are brighter, persistent methane clouds that form around the tropopause layer. The persistence of companion clouds shows that some former dark spots may continue to exist as cyclones even though they are no longer visible as a dark feature. Dark spots may dissipate when they migrate too close to the equator or possibly through some other unknown mechanism.
Try to answer this question if possible: Since Neptune's light spots persist for several months, what are they thought to be?
Answer: unanswerable

QUES: On February 29, 2012, Microsoft released Windows 8 Consumer Preview, the beta version of Windows 8, build 8250. Alongside other changes, the build removed the Start button from the taskbar for the first time since its debut on Windows 95; according to Windows manager Chaitanya Sareen, the Start button was removed to reflect their view that on Windows 8, the desktop was an "app" itself, and not the primary interface of the operating system. Windows president Steven Sinofsky said more than 100,000 changes had been made since the developer version went public. The day after its release, Windows 8 Consumer Preview had been downloaded over one million times. Like the Developer Preview, the Consumer Preview expired on January 15, 2013.
How many times was the Consumer Preview downloaded in the first 42 hours?
