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: A fine tribute to the fall of Warsaw and history of Poland can be found in the Warsaw Uprising Museum and in the Katyń Museum which preserves the memory of the crime. The Warsaw Uprising Museum also operates a rare preserved and operating historic stereoscopic theatre, the Warsaw Fotoplastikon. The Museum of Independence preserves patriotic and political objects connected with Poland's struggles for independence. Dating back to 1936 Warsaw Historical Museum contains 60 rooms which host a permanent exhibition of the history of Warsaw from its origins until today.

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).

Q: Passage: The pound-force has a metric counterpart, less commonly used than the newton: the kilogram-force (kgf) (sometimes kilopond), is the force exerted by standard gravity on one kilogram of mass. The kilogram-force leads to an alternate, but rarely used unit of mass: the metric slug (sometimes mug or hyl) is that mass that accelerates at 1 m·s−2 when subjected to a force of 1 kgf. The kilogram-force is not a part of the modern SI system, and is generally deprecated; however it still sees use for some purposes as expressing aircraft weight, jet thrust, bicycle spoke tension, torque wrench settings and engine output torque. Other arcane units of force include the sthène, which is equivalent to 1000 N, and the kip, which is equivalent to 1000 lbf.

A:
What does not have a metric counterpart?
