Input: Read this: Hunter-gatherer societies manifest significant variability, depending on climate zone/life zone, available technology and societal structure. Archaeologists examine hunter-gatherer tool kits to measure variability across different groups. Collard et al. (2005) found temperature to be the only statistically significant factor to impact hunter-gatherer tool kits. Using temperature as a proxy for risk, Collard et al.'s results suggest that environments with extreme temperatures pose a threat to hunter-gatherer systems significant enough to warrant increased variability of tools. These results support Torrence's (1989) theory that risk of failure is indeed the most important factor in determining the structure of hunter-gatherer toolkits.
Question: What does temperature impact on tool kits?

Output: increased variability of tools


QUES: In the 1980s, parents of mixed-race children began to organize and lobby for the addition of a more inclusive term of racial designation that would reflect the heritage of their children. When the U.S. government proposed the addition of the category of "bi-racial" or "multiracial" in 1988, the response from the public was mostly negative. Some African-American organizations, and African-American political leaders, such as Congresswoman Diane Watson and Congressman Augustus Hawkins, were particularly vocal in their rejection of the category, as they feared the loss of political and economic power if African Americans reduced their numbers by self-identification.

What could have cause loss of power via the use of the term biracial and multiracial?
What is the answer?
ANS: if African Americans reduced their numbers by self-identification


QUES: The remaining animals form a monophyletic group called the Bilateria. For the most part, they are bilaterally symmetric, and often have a specialized head with feeding and sensory organs. The body is triploblastic, i.e. all three germ layers are well-developed, and tissues form distinct organs. The digestive chamber has two openings, a mouth and an anus, and there is also an internal body cavity called a coelom or pseudocoelom. There are exceptions to each of these characteristics, however — for instance adult echinoderms are radially symmetric, and certain parasitic worms have extremely simplified body structures.
What is the internal body cavity of animals in the Bilateria group called?

ANS: coelom or pseudocoelom


As noted in the introduction to this article, the American public has maintained its position of support for capital punishment for murder. However, when given a choice between the death penalty and life imprisonment without parole, support has traditionally been significantly lower than polling which has only mentioned the death penalty as a punishment. In 2010, for instance, one poll showed 49 percent favoring the death penalty and 46 percent favoring life imprisonment while in another 61% said they preferred another punishment to the death penalty. The highest level of support for the death penalty recorded overall was 80 percent in 1994 (16 percent opposed), and the lowest recorded was 42 percent in 1966 (47 percent opposed). On the question of the death penalty vs. life without parole, the strongest preference for the death penalty was 61 percent in 1997 (29 percent favoring life), and the lowest preference for the death penalty was 47 percent in 2006 (48 percent favoring life).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In a 2006 poll, what percentage of polled Americans rejected the death penalty to life without parole?
Ah, so.. unanswerable


Question: In 1654, Otto von Guericke invented the first vacuum pump and conducted his famous Magdeburg hemispheres experiment, showing that teams of horses could not separate two hemispheres from which the air had been partially evacuated. Robert Boyle improved Guericke's design and with the help of Robert Hooke further developed vacuum pump technology. Thereafter, research into the partial vacuum lapsed until 1850 when August Toepler invented the Toepler Pump and Heinrich Geissler invented the mercury displacement pump in 1855, achieving a partial vacuum of about 10 Pa (0.1 Torr). A number of electrical properties become observable at this vacuum level, which renewed interest in further research.
Try to answer this question if possible: What did Heinrich Geissler help Otto von Guericke further develop?
Answer: unanswerable


QUES: As the school suffered reduced income while still under construction, the completion and further development of the school has since depended to some extent on wealthy benefactors. Building resumed when Roger Lupton was Provost, around 1517. His name is borne by the big gate-house in the west range of the cloisters, fronting School Yard, perhaps the most famous image of the school. This range includes the important interiors of the Parlour, Election Hall, and Election Chamber, where most of the 18th century "leaving portraits" are kept.
In what year was Election Hall built?
