QUES: The massive work was arranged according to a "tree of knowledge." The tree reflected the marked division between the arts and sciences, which was largely a result of the rise of empiricism. Both areas of knowledge were united by philosophy, or the trunk of the tree of knowledge. The Enlightenment's desacrilization of religion was pronounced in the tree's design, particularly where theology accounted for a peripheral branch, with black magic as a close neighbour. As the Encyclopedie gained popularity, it was published in quarto and octavo editions after 1777. The quarto and octavo editions were much less expensive than previous editions, making the Encyclopedie more accessible to the non-elite. Robert Darnton estimates that there were approximately 25 000 copies of the Encyclopedie in circulation throughout France and Europe before the French Revolution. The extensive, yet affordable encyclopedia came to represent the transmission of Enlightenment and scientific education to an expanding audience.

What was considered the trunk of the tree of knowledge?
What is the answer?
ANS: philosophy
QUES: The cosmopolitan and multicultural nature of modern Guam poses challenges for Chamorros struggling to preserve their culture and identity amidst forces of acculturation. The increasing numbers of Chamorros, especially Chamorro youth, relocating to the U.S. Mainland has further complicated both definition and preservation of Chamorro identity.[citation needed] While only a few masters exist to continue traditional art forms, the resurgence of interest among the Chamorros to preserve the language and culture has resulted in a growing number of young Chamorros who seek to continue the ancient ways of the Chamorro people.

Who have primarily relocated from the U.S. Mainland to Guam?
What is the answer?
ANS: unanswerable
QUES: Hydrogen production technologies been a significant area of solar chemical research since the 1970s. Aside from electrolysis driven by photovoltaic or photochemical cells, several thermochemical processes have also been explored. One such route uses concentrators to split water into oxygen and hydrogen at high temperatures (2,3002,600 C or 4,2004,700 F). Another approach uses the heat from solar concentrators to drive the steam reformation of natural gas thereby increasing the overall hydrogen yield compared to conventional reforming methods. Thermochemical cycles characterized by the decomposition and regeneration of reactants present another avenue for hydrogen production. The Solzinc process under development at the Weizmann Institute uses a 1 MW solar furnace to decompose zinc oxide (ZnO) at temperatures above 1,200 C (2,200 F). This initial reaction produces pure zinc, which can subsequently be reacted with water to produce hydrogen.

What is one of the thermochemical processes that has been explored besides electrolysis?
What is the answer?
ANS:
uses concentrators to split water into oxygen and hydrogen at high temperatures
