Problem: Hanover:

A cabinet of coins is the Münzkabinett der TUI-AG. The Polizeigeschichtliche Sammlung Niedersachsen is the largest police museum in Germany. Textiles from all over the world can be visited in the Museum for textile art. The EXPOseeum is the museum of the world-exhibition "EXPO 2000 Hannover". Carpets and objects from the orient can be visited in the Oriental Carpet Museum. The Blind Man Museum is a rarity in Germany, another one is only in Berlin. The Museum of veterinary medicine is unique in Germany. The Museum for Energy History describes the 150 years old history of the application of energy. The Home Museum Ahlem shows the history of the district of Ahlem. The Mahn- und Gedenkstätte Ahlem describes the history of the Jewish people in Hanover and the Stiftung Ahlers Pro Arte / Kestner Pro Arte shows modern art. Modern art is also the main topic of the Kunsthalle Faust, the Nord/LB Art Gellery and of the Foro Artistico / Eisfabrik.

Problem: On 27 August 2007, Royal Dutch Shell and Reitan Group, the owner of the 7-Eleven brand in Scandinavia, announced an agreement to re-brand some 269 service stations across Norway, Sweden, Finland and Denmark, subject to obtaining regulatory approvals under the different competition laws in each country. On April 2010 Shell announced that the corporation is in process of trying to find a potential buyer for all of its operations in Finland and is doing similar market research concerning Swedish operations. On October 2010 Shell's gas stations and the heavy vehicle fuel supply networks in Finland and Sweden, along with a refinery located in Gothenburg, Sweden were sold to St1, a Finnish energy company, more precisely to its major shareholding parent company Keele Oy. Shell branded gas stations will be rebranded within maximum of five years from the acquisition and the number of gas stations is likely to be reduced. Until then the stations will operate under Shell brand licence.
When did St1 and Reitan Group announce an agreement?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Polarization is the sum of the E-plane orientations over time projected onto an imaginary plane perpendicular to the direction of motion of the radio wave. In the most general case, polarization is elliptical, meaning that the polarization of the radio waves varies over time. Two special cases are linear polarization (the ellipse collapses into a line) as we have discussed above, and circular polarization (in which the two axes of the ellipse are equal). In linear polarization the electric field of the radio wave oscillates back and forth along one direction; this can be affected by the mounting of the antenna but usually the desired direction is either horizontal or vertical polarization. In circular polarization, the electric field (and magnetic field) of the radio wave rotates at the radio frequency circularly around the axis of propagation. Circular or elliptically polarized radio waves are designated as right-handed or left-handed using the "thumb in the direction of the propagation" rule. Note that for circular polarization, optical researchers use the opposite right hand rule from the one used by radio engineers.
What are electrical fields projected on to?
A: imaginary plane


Context and question: Some Western writers claim that the immaculate conception of Mary is a teaching of Islam. Thus, commenting in 1734 on the passage in the Qur'an, "I have called her Mary; and I commend her to thy protection, and also her issue, against Satan driven away with stones", George Sale stated: "It is not improbable that the pretended immaculate conception of the virgin Mary is intimated in this passage. For according to a tradition of Mohammed, every person that comes into the world, is touched at his birth by the devil, and therefore cries out, Mary and her son only excepted; between whom, and the evil spirit God placed a veil, so that his touch did not reach them. And for this reason they say, neither of them were guilty of any sin, like the rest of the children of Adam."
Who says it is not that the concept of the Immaculat conception is taken from the Qur'an?

Question: When power is lost in a traction elevator system, all elevators will initially come to a halt. One by one, each car in the group will return to the lobby floor, open its doors and shut down. People in the remaining elevators may see an indicator light or hear a voice announcement informing them that the elevator will return to the lobby shortly. Once all cars have successfully returned, the system will then automatically select one or more cars to be used for normal operations and these cars will return to service. The car(s) selected to run under emergency power can be manually overridden by a key or strip switch in the lobby. In order to help prevent entrapment, when the system detects that it is running low on power, it will bring the running cars to the lobby or nearest floor, open the doors and shut down.
Is there an answer to this question: What do any passengers experience at this point?

Answer: People in the remaining elevators may see an indicator light or hear a voice announcement informing them that the elevator will return to the lobby shortly


Within six years of the official criminalization of heresy by the Emperor, the first Christian heretic to be executed, Priscillian, was condemned in 386 by Roman secular officials for sorcery, and put to death with four or five followers. However, his accusers were excommunicated both by Ambrose of Milan and Pope Siricius, who opposed Priscillian's heresy, but "believed capital punishment to be inappropriate at best and usually unequivocally evil". For some years after the Reformation, Protestant churches were also known to execute those they considered heretics, including Catholics. The last known heretic executed by sentence of the Roman Catholic Church was Spanish schoolmaster Cayetano Ripoll in 1826. The number of people executed as heretics under the authority of the various "ecclesiastical authorities"[note 1] is not known.[note 2] One of the first examples of the word as translated from the Nag Hammadi's Apocalypse of Peter was" they will cleave to the name of a dead man thinking that they will become pure. But they will become greatly defiled and they will fall into the name of error and into the hands of an evil cunning man and a manifold dogma, and they will be ruled heretically".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who excommunicated Priscillian?
Ah, so..
unanswerable
