Input: Read this: The Han-era Chinese sailed in a variety of ships differing from those of previous eras, such as the tower ship. The junk design was developed and realized during Han. Junks featured a square-ended bow and stern, a flat-bottomed hull or carvel-shaped hull with no keel or sternpost, and solid transverse bulkheads in the place of structural ribs found in Western vessels. Moreover, Han ships were the first in the world to be steered using a rudder at the stern, in contrast to the simpler steering oar used for riverine transport, allowing them to sail on the high seas.
Question: What ship design contained a flat-bottomed hull?

Output: Junks

QUES: Kaszycka et al. (2009) in 20022003 surveyed European anthropologists' opinions toward the biological race concept. Three factors, country of academic education, discipline, and age, were found to be significant in differentiating the replies. Those educated in Western Europe, physical anthropologists, and middle-aged persons rejected race more frequently than those educated in Eastern Europe, people in other branches of science, and those from both younger and older generations." The survey shows that the views on race are sociopolitically (ideologically) influenced and highly dependent on education."

What did the people educated in Western Europe reject more frequently than those educated in Eastern Europe?
What is the answer?
ANS: race

QUES: By contrast, Tom Wolfe's Bonfire of the Vanities (1987) portrays a wealthy, white protagonist, Sherman McCoy, getting lost off the Major Deegan Expressway in the South Bronx and having an altercation with locals. A substantial piece of the last part of the book is set in the resulting riotous trial at the Bronx County Courthouse. However, times change, and in 2007, the New York Times reported that "the Bronx neighborhoods near the site of Sherman's accident are now dotted with townhouses and apartments." In the same article, the Reverend Al Sharpton (whose fictional analogue in the novel is "Reverend Bacon") asserts that "twenty years later, the cynicism of The Bonfire of the Vanities is as out of style as Tom Wolfe's wardrobe."
When was 'Bonfire of the Vanities' published?

ANS: 1987

Later interpretations of Avicenna's philosophy split into three different schools; those (such as al-Tusi) who continued to apply his philosophy as a system to interpret later political events and scientific advances; those (such as al-Razi) who considered Avicenna's theological works in isolation from his wider philosophical concerns; and those (such as al-Ghazali) who selectively used parts of his philosophy to support their own attempts to gain greater spiritual insights through a variety of mystical means. It was the theological interpretation championed by those such as al-Razi which eventually came to predominate in the madrasahs.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who used Avicenna's work to help understand future political events?
Ah, so.. al-Tusi

Question: Wood to be used for construction work is commonly known as lumber in North America. Elsewhere, lumber usually refers to felled trees, and the word for sawn planks ready for use is timber. In Medieval Europe oak was the wood of choice for all wood construction, including beams, walls, doors, and floors. Today a wider variety of woods is used: solid wood doors are often made from poplar, small-knotted pine, and Douglas fir.
Try to answer this question if possible: Outside of North America, if someone said "lumber," to what would they be referring?
Answer: felled trees

Input: Read this: The transition from hunting and gathering to agriculture is not necessarily a one way process. It has been argued that hunting and gathering represents an adaptive strategy, which may still be exploited, if necessary, when environmental change causes extreme food stress for agriculturalists. In fact, it is sometimes difficult to draw a clear line between agricultural and hunter-gatherer societies, especially since the widespread adoption of agriculture and resulting cultural diffusion that has occurred in the last 10,000 years.[citation needed] This anthropological view has remained unchanged since the 1960s.[clarification needed][citation needed]
Question: It is easy to draw a clear line between what?

Output:
unanswerable
