Problem: The Paris region hosts France's highest concentration of the grandes ecoles 55 specialised centres of higher-education outside the public university structure. The prestigious public universities are usually considered grands etablissements. Most of the grandes ecoles were relocated to the suburbs of Paris in the 1960s and 1970s, in new campuses much larger than the old campuses within the crowded city of Paris, though the Ecole Normale Superieure has remained on rue d'Ulm in the 5th arrondissement. There are a high number of engineering schools, led by the Paris Institute of Technology which comprises several colleges such as Ecole Polytechnique, Ecole des Mines, AgroParisTech, Telecom Paris, Arts et Metiers, and Ecole des Ponts et Chaussees. There are also many business schools, including HEC, INSEAD, ESSEC, and ESCP Europe. The administrative school such as ENA has been relocated to Strasbourg, the political science school Sciences-Po is still located in Paris' 7th arrondissement and the most prestigious university of economics and finance, Paris-Dauphine, is located in Paris' 16th. The Parisian school of journalism CELSA department of the Paris-Sorbonne University is located in Neuilly-sur-Seine. Paris is also home to several of France's most famous high-schools such as Lycee Louis-le-Grand, Lycee Henri-IV, Lycee Janson de Sailly and Lycee Condorcet. The National Institute of Sport and Physical Education, located in the 12th arrondissement, is both a physical education institute and high-level training centre for elite athletes.
During which time frame were most grandes ecoles relocated?

Answer: 1960s and 1970s

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The immediate cause of the war resided in the candidacy of a Leopold of Hohenzollern-Sigmaringen, a Prussian prince, to the throne of Spain. France feared encirclement by an alliance between Prussia and Spain. The Hohenzollern prince's candidacy was withdrawn under French diplomatic pressure, but Otto von Bismarck goaded the French into declaring war by altering a telegram sent by William I. Releasing the Ems Dispatch to the public, Bismarck made it sound as if the king had treated the French envoy in a demeaning fashion, which inflamed public opinion in France.
In whose cadidacy did the immediate cause of war reside?
A: Leopold of Hohenzollern-Sigmaringen

Context and question: Mill's empiricism thus held that knowledge of any kind is not from direct experience but an inductive inference from direct experience. The problems other philosophers have had with Mill's position center around the following issues: Firstly, Mill's formulation encounters difficulty when it describes what direct experience is by differentiating only between actual and possible sensations. This misses some key discussion concerning conditions under which such "groups of permanent possibilities of sensation" might exist in the first place. Berkeley put God in that gap; the phenomenalists, including Mill, essentially left the question unanswered. In the end, lacking an acknowledgement of an aspect of "reality" that goes beyond mere "possibilities of sensation", such a position leads to a version of subjective idealism. Questions of how floor beams continue to support a floor while unobserved, how trees continue to grow while unobserved and untouched by human hands, etc., remain unanswered, and perhaps unanswerable in these terms. Secondly, Mill's formulation leaves open the unsettling possibility that the "gap-filling entities are purely possibilities and not actualities at all". Thirdly, Mill's position, by calling mathematics merely another species of inductive inference, misapprehends mathematics. It fails to fully consider the structure and method of mathematical science, the products of which are arrived at through an internally consistent deductive set of procedures which do not, either today or at the time Mill wrote, fall under the agreed meaning of induction.
What sensations did Mill differentiate?
Answer: actual and possible sensations

Question: In the sixth edition Darwin inserted a new chapter VII (renumbering the subsequent chapters) to respond to criticisms of earlier editions, including the objection that many features of organisms were not adaptive and could not have been produced by natural selection. He said some such features could have been by-products of adaptive changes to other features, and that often features seemed non-adaptive because their function was unknown, as shown by his book on Fertilisation of Orchids that explained how their elaborate structures facilitated pollination by insects. Much of the chapter responds to George Jackson Mivart's criticisms, including his claim that features such as baleen filters in whales, flatfish with both eyes on one side and the camouflage of stick insects could not have evolved through natural selection because intermediate stages would not have been adaptive. Darwin proposed scenarios for the incremental evolution of each feature.
Is there an answer to this question: Why did Darwin introduce a new chapter in On the Origin of Species in the sixth edition?

Answer: to respond to criticisms of earlier editions

Question: Natural uranium consists of three major isotopes: uranium-238 (99.28% natural abundance), uranium-235 (0.71%), and uranium-234 (0.0054%). All three are radioactive, emitting alpha particles, with the exception that all three of these isotopes have small probabilities of undergoing spontaneous fission, rather than alpha emission. There are also five other trace isotopes: uranium-239, which is formed when 238U undergoes spontaneous fission, releasing neutrons that are captured by another 238U atom; uranium-237, which is formed when 238U captures a neutron but emits two more, which then decays to neptunium-237; uranium-233, which is formed in the decay chain of that neptunium-237; and finally, uranium-236 and -240, which appear in the decay chain of primordial plutonium-244. It is also expected that thorium-232 should be able to undergo double beta decay, which would produce uranium-232, but this has not yet been observed experimentally.
Is there an answer to this question: What is the least prevalent major isotope of unnatural uranium?

Answer:
unanswerable
