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: Similar to the problems of defining literature and film, no consensus has been reached on a definition of the comics medium, and attempted definitions and descriptions have fallen prey to numerous exceptions. Theorists such as Topffer, R. C. Harvey, Will Eisner, David Carrier, Alain Rey, and Lawrence Grove emphasize the combination of text and images, though there are prominent examples of pantomime comics throughout its history. Other critics, such as Thierry Groensteen and Scott McCloud, have emphasized the primacy of sequences of images. Towards the close of the 20th century, different cultures' discoveries of each other's comics traditions, the rediscovery of forgotten early comics forms, and the rise of new forms made defining comics a more complicated task.
A:
