Question: Late Carboniferous and Early Permian insect orders include both extant groups, their stem groups, and a number of Paleozoic groups, now extinct. During this era, some giant dragonfly-like forms reached wingspans of 55 to 70 cm (22 to 28 in), making them far larger than any living insect. This gigantism may have been due to higher atmospheric oxygen levels that allowed increased respiratory efficiency relative to today. The lack of flying vertebrates could have been another factor. Most extinct orders of insects developed during the Permian period that began around 270 million years ago. Many of the early groups became extinct during the Permian-Triassic extinction event, the largest mass extinction in the history of the Earth, around 252 million years ago.
Is there an answer to this question: To what measurement, in cm, did the wingspans of giant dragonfly-like forms reach?

Answer: 55 to 70


Question: Under the Capetian dynasty France slowly began to expand its authority over the nobility, growing out of the Île-de-France to exert control over more of the country in the 11th and 12th centuries. They faced a powerful rival in the Dukes of Normandy, who in 1066 under William the Conqueror (duke 1035–1087), conquered England (r. 1066–87) and created a cross-channel empire that lasted, in various forms, throughout the rest of the Middle Ages. Normans also settled in Sicily and southern Italy, when Robert Guiscard (d. 1085) landed there in 1059 and established a duchy that later became the Kingdom of Sicily. Under the Angevin dynasty of Henry II (r. 1154–89) and his son Richard I (r. 1189–99), the kings of England ruled over England and large areas of France,[W] brought to the family by Henry II's marriage to Eleanor of Aquitaine (d. 1204), heiress to much of southern France.[X] Richard's younger brother John (r. 1199–1216) lost Normandy and the rest of the northern French possessions in 1204 to the French King Philip II Augustus (r. 1180–1223). This led to dissension among the English nobility, while John's financial exactions to pay for his unsuccessful attempts to regain Normandy led in 1215 to Magna Carta, a charter that confirmed the rights and privileges of free men in England. Under Henry III (r. 1216–72), John's son, further concessions were made to the nobility, and royal power was diminished. The French monarchy continued to make gains against the nobility during the late 12th and 13th centuries, bringing more territories within the kingdom under their personal rule and centralising the royal administration. Under Louis IX (r. 1226–70), royal prestige rose to new heights as Louis served as a mediator for most of Europe.[Y]
Is there an answer to this question: To what dynasty did Henry II belong?

Answer: Angevin


Question: In 1808 Bavarian educational commissioner Friedrich Immanuel Niethammer coined the term Humanismus to describe the new classical curriculum he planned to offer in German secondary schools, and by 1836 the word "humanism" had been absorbed into the English language in this sense. The coinage gained universal acceptance in 1856, when German historian and philologist Georg Voigt used humanism to describe Renaissance humanism, the movement that flourished in the Italian Renaissance to revive classical learning, a use which won wide acceptance among historians in many nations, especially Italy.
Is there an answer to this question: What nation was not receptive to the new definition of this concept?

Answer: unanswerable


Question: European cultural ideas and institutions began to follow colonial expansion into other parts of the world. There was also a rise, especially toward the end of the era, of nationalism in music (echoing, in some cases, political sentiments of the time), as composers such as Edvard Grieg, Nikolai Rimsky-Korsakov, and Antonín Dvořák echoed traditional music of their homelands in their compositions.
