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: Coulton Waugh attempted the first comprehensive history of American comics with The Comics (1947). Will Eisner's Comics and Sequential Art (1985) and Scott McCloud's Understanding Comics (1993) were early attempts in English to formalize the study of comics. David Carrier's The Aesthetics of Comics (2000) was the first full-length treatment of comics from a philosophical perspective. Prominent American attempts at definitions of comics include Eisner's, McCloud's, and Harvey's. Eisner described what he called "sequential art" as "the arrangement of pictures or images and words to narrate a story or dramatize an idea"; Scott McCloud defined comics "juxtaposed pictorial and other images in deliberate sequence, intended to convey information and/or to produce an aesthetic response in the viewer", a strictly formal definition which detached comics from its historical and cultural trappings. R. C. Harvey defined comics as "pictorial narratives or expositions in which words (often lettered into the picture area within speech balloons) usually contribute to the meaning of the pictures and vice versa". Each definition has had its detractors. Harvey saw McCloud's definition as excluding single-panel cartoons, and objected to McCloud's de-emphasizing verbal elements, insisting "the essential characteristic of comics is the incorporation of verbal content". Aaron Meskin saw McCloud's theories as an artificial attempt to legitimize the place of comics in art history.
[A]: Who put together a history of American comics in 1974?


[Q]: Passage: The time and space hierarchy theorems form the basis for most separation results of complexity classes. For instance, the time hierarchy theorem tells us that P is strictly contained in EXPTIME, and the space hierarchy theorem tells us that L is strictly contained in PSPACE.
[A]: What does not form the basis for most separation results of complexity classes?


[Q]: Passage: Among the notable structures in the town are the three forts built by the Swedes for defense purposes. One of these forts, known as Fort Oscar (formerly Gustav Adolph), which overlooks the sea is located on the far side of La Pointe. However, the ruins have been replaced by a modern military building which now houses the local gendarmerie. The other fort known as Fort Karl now presents a very few ruins. The third fort built by the Swedes is the Fort Gustav, which is also seen in ruins strewn around the weather station and the Light House. The fort built in 1787 over a hill slope has ruins of ramparts, guardhouse, munitions depot, wood-burning oven and so forth.
[A]:
In what year was Gustav Adolph built?
