Problem: Qing dynasty:

The government broadened land ownership by returning land that had been sold to large landowners in the late Ming period by families unable to pay the land tax. To give people more incentives to participate in the market, they reduced the tax burden in comparison with the late Ming, and replaced the corvee system with a head tax used to hire laborers. The administration of the Grand Canal was made more efficient, and transport opened to private merchants. A system of monitoring grain prices eliminated severe shortages, and enabled the price of rice to rise slowly and smoothly through the 18th century. Wary of the power of wealthy merchants, Qing rulers limited their trading licenses and usually refused them permission to open new mines, except in poor areas. These restrictions on domestic resource exploration, as well as on foreign trade, are held by some scholars as a cause of the Great Divergence, by which the Western world overtook China economically.

What happened to the price of rice during the 18th century?
---
A: rise slowly and smoothly

Problem: In 1966, Yale began discussions with its sister school Vassar College about merging to foster coeducation at the undergraduate level. Vassar, then all-female and part of the Seven Sisterselite higher education schools that historically served as sister institutions to the Ivy League when the Ivy League still only admitted mententatively accepted, but then declined the invitation. Both schools introduced coeducation independently in 1969. Amy Solomon was the first woman to register as a Yale undergraduate; she was also the first woman at Yale to join an undergraduate society, St. Anthony Hall. The undergraduate class of 1973 was the first class to have women starting from freshman year; at the time, all undergraduate women were housed in Vanderbilt Hall at the south end of Old Campus.[citation needed]
What year did the first undergraduate class including women graduate from Yale?
---
Answer: 1973

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Bronze Age arrived circa 1500 BC when people in the region were turning copper into bronze, growing rice and domesticating poultry and pigs; they were among the first people in the world to do so. Human remains and artifacts from this era were discovered in Monywa District in the Sagaing Division. The Iron Age began around 500 BC with the emergence of iron-working settlements in an area south of present-day Mandalay. Evidence also shows the presence of rice-growing settlements of large villages and small towns that traded with their surroundings as far as China between 500 BC and 200 AD. Iron Age Burmese cultures also had influences from outside sources such as India and Thailand, as seen in their funerary practices concerning child burials. This indicates some form of communication between groups in Myanmar and other places, possibly through trade.
What event evolving animals are the Myanmar also accredited with being the first to accomplish?
A: domesticating poultry and pigs

Context and question: Most breeds of dog are at most a few hundred years old, having been artificially selected for particular morphologies and behaviors by people for specific functional roles. Through this selective breeding, the dog has developed into hundreds of varied breeds, and shows more behavioral and morphological variation than any other land mammal. For example, height measured to the withers ranges from 15.2 centimetres (6.0 in) in the Chihuahua to about 76 cm (30 in) in the Irish Wolfhound; color varies from white through grays (usually called "blue") to black, and browns from light (tan) to dark ("red" or "chocolate") in a wide variation of patterns; coats can be short or long, coarse-haired to wool-like, straight, curly, or smooth. It is common for most breeds to shed this coat.
Gray color is often called what when referring to dogs?
Answer: blue

Question: Wood has been an important construction material since humans began building shelters, houses and boats. Nearly all boats were made out of wood until the late 19th century, and wood remains in common use today in boat construction. Elm in particular was used for this purpose as it resisted decay as long as it was kept wet (it also served for water pipe before the advent of more modern plumbing).
Is there an answer to this question: What significant purpose has wood been used for as long as humans have built shelters?

Answer: construction material

QUES: Avicenna's astronomical writings had some influence on later writers, although in general his work could be considered less developed than Alhazen or Al-Biruni. One important feature of his writing is that he considers mathematical astronomy as a separate discipline to astrology. He criticized Aristotle's view of the stars receiving their light from the Sun, stating that the stars are self-luminous, and believed that the planets are also self-luminous. He claimed to have observed Venus as a spot on the Sun. This is possible, as there was a transit on May 24, 1032, but Avicenna did not give the date of his observation, and modern scholars have questioned whether he could have observed the transit from his location at that time; he may have mistaken a sunspot for Venus. He used his transit observation to help establish that Venus was, at least sometimes, below the Sun in Ptolemaic cosmology, i.e. the sphere of Venus comes before the sphere of the Sun when moving out from the Earth in the prevailing geocentric model.
