Article: 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.

Question: Which editions of the Encyclopedie were less expensive and more accessible to the non-elite?
Ans: quarto and octavo

Article: The first Industrial Revolution merged into the Second Industrial Revolution around 1850, when technological and economic progress gained momentum with the development of steam-powered ships and railways, and later in the 19th century with the internal combustion engine and electric power generation. The Second Industrial Revolution was a phase of the Industrial Revolution; labeled as the separate Technical Revolution. From a technological and a social point of view there is no clean break between the two. Major innovations during the period occurred in the chemical, electrical, petroleum, and steel industries. Specific advancements included the introduction of oil fired steam turbine and internal combustion driven steel ships, the development of the airplane, the practical commercialization of the automobile, mass production of consumer goods, the perfection of canning, mechanical refrigeration and other food preservation techniques, and the invention of the telephone.

Question: The 19th century was also known as?
Ans: the internal combustion engine and electric power generation.

Article: The Frankish kingdom in northern Gaul split into kingdoms called Austrasia, Neustria, and Burgundy during the 6th and 7th centuries, all of them ruled by the Merovingian dynasty, who were descended from Clovis. The 7th century was a tumultuous period of wars between Austrasia and Neustria. Such warfare was exploited by Pippin (d. 640), the Mayor of the Palace for Austrasia who became the power behind the Austrasian throne. Later members of his family inherited the office, acting as advisers and regents. One of his descendants, Charles Martel (d. 741), won the Battle of Poitiers in 732, halting the advance of Muslim armies across the Pyrenees.[K] Great Britain was divided into small states dominated by the kingdoms of Northumbria, Mercia, Wessex, and East Anglia, which were descended from the Anglo-Saxon invaders. Smaller kingdoms in present-day Wales and Scotland were still under the control of the native Britons and Picts. Ireland was divided into even smaller political units, usually known as tribal kingdoms, under the control of kings. There were perhaps as many as 150 local kings in Ireland, of varying importance.

Question: What leader was victorious at the Battle of Poitiers?
Ans: Charles Martel

Article: The Roman Republic (Latin: Res publica Romana; Classical Latin: [res pub.l.ka roma.na]) was the period of ancient Roman civilization beginning with the overthrow of the Roman Kingdom, traditionally dated to 509 BC, and ending in 27 BC with the establishment of the Roman Empire. It was during this period that Rome's control expanded from the city's immediate surroundings to hegemony over the entire Mediterranean world. During the first two centuries of its existence, the Roman Republic expanded through a combination of conquest and alliance, from central Italy to the entire Italian peninsula. By the following century, it included North Africa, Spain, and what is now southern France. Two centuries after that, towards the end of the 1st century BC, it included the rest of modern France, Greece, and much of the eastern Mediterranean. By this time, internal tensions led to a series of civil wars, culminating with the assassination of Julius Caesar, which led to the transition from republic to empire. The exact date of transition can be a matter of interpretation. Historians have variously proposed Julius Caesar's crossing of the Rubicon River in 49 BC, Caesar's appointment as dictator for life in 44 BC, and the defeat of Mark Antony and Cleopatra at the Battle of Actium in 31 BC. However, most use the same date as did the ancient Romans themselves, the Roman Senate's grant of extraordinary powers to Octavian and his adopting the title Augustus in 27 BC, as the defining event ending the Republic.

Question: What do most consider to be the event that ended the Roman Republic?
Ans:
Roman Senate's grant of extraordinary powers to Octavian
