This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

Q: Passage: For air dielectric capacitors the breakdown field strength is of the order 2 to 5 MV/m; for mica the breakdown is 100 to 300 MV/m; for oil, 15 to 25 MV/m; it can be much less when other materials are used for the dielectric. The dielectric is used in very thin layers and so absolute breakdown voltage of capacitors is limited. Typical ratings for capacitors used for general electronics applications range from a few volts to 1 kV. As the voltage increases, the dielectric must be thicker, making high-voltage capacitors larger per capacitance than those rated for lower voltages. The breakdown voltage is critically affected by factors such as the geometry of the capacitor conductive parts; sharp edges or points increase the electric field strength at that point and can lead to a local breakdown. Once this starts to happen, the breakdown quickly tracks through the dielectric until it reaches the opposite plate, leaving carbon behind and causing a short (or relatively low resistance) circuit. The results can be explosive as the short in the capacitor draws current from the surrounding circuitry and dissipates the energy.

A: What order is the breakdown field weakness for air dielectric capacitors of?

Q: Passage: At the 1912 Salon d'Automne an architectural installation was exhibited that quickly became known as Maison Cubiste (Cubist House), signed Raymond Duchamp-Villon and André Mare along with a group of collaborators. Metzinger and Gleizes in Du "Cubisme", written during the assemblage of the "Maison Cubiste", wrote about the autonomous nature of art, stressing the point that decorative considerations should not govern the spirit of art. Decorative work, to them, was the "antithesis of the picture". "The true picture" wrote Metzinger and Gleizes, "bears its raison d'être within itself. It can be moved from a church to a drawing-room, from a museum to a study. Essentially independent, necessarily complete, it need not immediately satisfy the mind: on the contrary, it should lead it, little by little, towards the fictitious depths in which the coordinative light resides. It does not harmonize with this or that ensemble; it harmonizes with things in general, with the universe: it is an organism...". "Mare's ensembles were accepted as frames for Cubist works because they allowed paintings and sculptures their independence", writes Christopher Green, "creating a play of contrasts, hence the involvement not only of Gleizes and Metzinger themselves, but of Marie Laurencin, the Duchamp brothers (Raymond Duchamp-Villon designed the facade) and Mare's old friends Léger and Roger La Fresnaye". La Maison Cubiste was a fully furnished house, with a staircase, wrought iron banisters, a living room—the Salon Bourgeois, where paintings by Marcel Duchamp, Metzinger (Woman with a Fan), Gleizes, Laurencin and Léger were hung—and a bedroom. It was an example of L'art décoratif, a home within which Cubist art could be displayed in the comfort and style of modern, bourgeois life. Spectators at the Salon d'Automne passed through the full-scale 10-by-3-meter plaster model of the ground floor of the facade, designed by Duchamp-Villon. This architectural installation was subsequently exhibited at the 1913 Armory Show, New York, Chicago and Boston, listed in the catalogue of the New York exhibit as Raymond Duchamp-Villon, number 609, and entitled "Facade architectural, plaster" (Façade architecturale).

A: What type of boat was La Maison Cubist?

Q: Passage: On 14 May 1955, the USSR and other seven European countries "reaffirming their desire for the establishment of a system of European collective security based on the participation of all European states irrespective of their social and political systems" established the Warsaw Pact in response to the integration of the Federal Republic of Germany into NATO, declaring that: "a remilitarized Western Germany and the integration of the latter in the North-Atlantic bloc [...] increase the danger of another war and constitutes a threat to the national security of the peaceable states; [...] in these circumstances the peaceable European states must take the necessary measures to safeguard their security".

A:
The USSR and eight other European countries formed the Warsaw Pact on what date?
