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.

Example Input: Passage: The three brothers—Rurik, Sineus, and Truvor—established themselves in Novgorod, Beloozero, and Izborsk, respectively. Two of the brothers died, and Rurik became the sole ruler of the territory and progenitor of the Rurik Dynasty. A short time later, two of Rurik’s men, Askold and Dir, asked him for permission to go to Tsargrad (Constantinople). On their way south, they discovered "a small city on a hill," Kiev, captured it and the surrounding country from the Khazars, populated the region with more Varangians, and "established their dominion over the country of the Polyanians."
Example Output: What were the names of the three sisters that ruled Novgorod, Beloozero, and Izborsk?

Example Input: Passage: In Lebanon, a part of the Christian population considers "Lebanese" to be in some sense a distinct language from Arabic and not merely a dialect. During the civil war Christians often used Lebanese Arabic officially, and sporadically used the Latin script to write Lebanese, thus further distinguishing it from Arabic. All Lebanese laws are written in the standard literary form of Arabic, though parliamentary debate may be conducted in Lebanese Arabic.
Example Output: Where is Lebanese considered a dialect and not a distinct language?

Example Input: Passage: Historical narratives of manga tend to focus either on its recent, post-WWII history, or on attempts to demonstrates deep roots in the past, such as to the Chōjū-jinbutsu-giga picture scroll of the 12th and 13th centuries, or the early 19th-century Hokusai Manga. The first historical overview of Japanese comics was Seiki Hosokibara's Nihon Manga-Shi[i] in 1924. Early post-war Japanese criticism was mostly of a left-wing political nature until the 1986 publication for Tomofusa Kure's Modern Manga: The Complete Picture,[j] which de-emphasized politics in favour of formal aspects, such as structure and a "grammar" of comics. The field of manga studies increased rapidly, with numerous books on the subject appearing in the 1990s. Formal theories of manga have focused on developing a "manga expression theory",[k] with emphasis on spatial relationships in the structure of images on the page, distinguishing the medium from film or literature, in which the flow of time is the basic organizing element. Comics studies courses have proliferated at Japanese universities, and Japan Society for Studies in Cartoon and Comics (ja)[l] was established in 2001 to promote comics scholarship. The publication of Frederik L. Schodt's Manga! Manga! The World of Japanese Comics in 1983 led to the spread of use of the word manga outside Japan to mean "Japanese comics" or "Japanese-style comics".
Example Output:
Which historical overview did Seiki Hosokibara reject?
