Article: The earliest known macrofossil confidently identified as an angiosperm, Archaefructus liaoningensis, is dated to about 125 million years BP (the Cretaceous period), whereas pollen considered to be of angiosperm origin takes the fossil record back to about 130 million years BP. However, one study has suggested that the early-middle Jurassic plant Schmeissneria, traditionally considered a type of ginkgo, may be the earliest known angiosperm, or at least a close relative. In addition, circumstantial chemical evidence has been found for the existence of angiosperms as early as 250 million years ago. Oleanane, a secondary metabolite produced by many flowering plants, has been found in Permian deposits of that age together with fossils of gigantopterids. Gigantopterids are a group of extinct seed plants that share many morphological traits with flowering plants, although they are not known to have been flowering plants themselves.

Question: When is the earliest known macrofossil identified as an angiosperm dated?
Ans: about 125 million years BP

Article: In recognition of his senior position in the Allied command, on December 20, 1944, he was promoted to General of the Army, equivalent to the rank of Field Marshal in most European armies. In this and the previous high commands he held, Eisenhower showed his great talents for leadership and diplomacy. Although he had never seen action himself, he won the respect of front-line commanders. He interacted adeptly with allies such as Winston Churchill, Field Marshal Bernard Montgomery and General Charles de Gaulle. He had serious disagreements with Churchill and Montgomery over questions of strategy, but these rarely upset his relationships with them. He dealt with Soviet Marshal Zhukov, his Russian counterpart, and they became good friends.

Question: What European rank was equivalent to that of General of the Army?
Ans: Field Marshal

Article: Over time, the relative power of these five nations fluctuated, which by the dawn of the 20th century had served to create an entirely different balance of power. Some, such as the United Kingdom and Prussia (as the founder of the newly formed German state), experienced continued economic growth and political power. Others, such as Russia and Austria-Hungary, stagnated. At the same time, other states were emerging and expanding in power, largely through the process of industrialization. These countries seeking to attain great power status were: Italy after the Risorgimento, Japan after the Meiji Restoration, and the United States after its civil war. By the dawn of the 20th century, the balance of world power had changed substantially since the Congress of Vienna. The Eight-Nation Alliance was a belligerent alliance of eight nations against the Boxer Rebellion in China. It formed in 1900 and consisted of the five Congress powers plus Italy, Japan, and the United States, representing the great powers at the beginning of 20th century.

Question: What countries found their economic growth in early 20th century?
Ans: United Kingdom and Prussia

Article: Neoclassicism also influenced city planning; the ancient Romans had used a consolidated scheme for city planning for both defence and civil convenience, however, the roots of this scheme go back to even older civilizations. At its most basic, the grid system of streets, a central forum with city services, two main slightly wider boulevards, and the occasional diagonal street were characteristic of the very logical and orderly Roman design. Ancient facades and building layouts were oriented to these city design patterns and they tended to work in proportion with the importance of public buildings.

Question: What basic civil planning system for streets is rooted in neoclassicism?
Ans:
grid system
