Article: The Appalachian belt includes, with the ranges enumerated above, the plateaus sloping southward to the Atlantic Ocean in New England, and south-eastward to the border of the coastal plain through the central and southern Atlantic states; and on the north-west, the Allegheny and Cumberland plateaus declining toward the Great Lakes and the interior plains. A remarkable feature of the belt is the longitudinal chain of broad valleys, including The Great Appalachian Valley, which in the southerly sections divides the mountain system into two unequal portions, but in the northernmost lies west of all the ranges possessing typical Appalachian features, and separates them from the Adirondack group. The mountain system has no axis of dominating altitudes, but in every portion the summits rise to rather uniform heights, and, especially in the central section, the various ridges and intermontane valleys have the same trend as the system itself. None of the summits reaches the region of perpetual snow.

Question: What is common among all the mountains in the range?
Ans: has no axis of dominating altitudes, but in every portion the summits rise to rather uniform heights


Here is a question about this article: World War I was a watershed event in human history, changing views of governments and politics. The Russian Revolution of 1917 (and similar, albeit less successful, revolutions in many other European countries) brought communism - and in particular the political theory of Leninism, but also on a smaller level Luxemburgism (gradually) - on the world stage. At the same time, social democratic parties won elections and formed governments for the first time, often as a result of the introduction of universal suffrage. However, a group of central European economists led by Austrian School economists Ludwig von Mises and Friedrich Hayek identified the collectivist underpinnings to the various new socialist and fascist doctrines of government power as being different brands of political totalitarianism.
What is the answer to this question: What brought communism?
****
So... The Russian Revolution of 1917

Problem: Please answer a question about the following article about Napoleon:
Following his triumph, Napoleon imposed the first elements of the Continental System through the Berlin Decree issued in November 1806. The Continental System, which prohibited European nations from trading with Britain, was widely violated throughout his reign. In the next few months, Napoleon marched against the advancing Russian armies through Poland and was involved in the bloody stalemate at the Battle of Eylau in February 1807. After a period of rest and consolidation on both sides, the war restarted in June with an initial struggle at Heilsberg that proved indecisive. On 14 June, however, Napoleon finally obtained an overwhelming victory over the Russians at the Battle of Friedland, wiping out the majority of the Russian army in a very bloody struggle. The scale of their defeat convinced the Russians to make peace with the French. On 19 June, Czar Alexander sent an envoy to seek an armistice with Napoleon. The latter assured the envoy that the Vistula River represented the natural borders between French and Russian influence in Europe. On that basis, the two emperors began peace negotiations at the town of Tilsit after meeting on an iconic raft on the River Niemen. The very first thing Alexander said to Napoleon was probably well-calibrated: "I hate the English as much as you do."
In what year was the Battle of Eylau?
A: 1807


Question: Read this and answer the question

Several instances of popular etymology are attested from ancient authors. Thus, the Greeks most often associated Apollo's name with the Greek verb ἀπόλλυμι (apollymi), "to destroy". Plato in Cratylus connects the name with ἀπόλυσις (apolysis), "redemption", with ἀπόλουσις (apolousis), "purification", and with ἁπλοῦν ([h]aploun), "simple", in particular in reference to the Thessalian form of the name, Ἄπλουν, and finally with Ἀειβάλλων (aeiballon), "ever-shooting". Hesychius connects the name Apollo with the Doric ἀπέλλα (apella), which means "assembly", so that Apollo would be the god of political life, and he also gives the explanation σηκός (sekos), "fold", in which case Apollo would be the god of flocks and herds. In the Ancient Macedonian language πέλλα (pella) means "stone," and some toponyms may be derived from this word: Πέλλα (Pella, the capital of Ancient Macedonia) and Πελλήνη (Pellēnē/Pallene).

What Doric word means assembly?
Answer: apella
