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.

Input: Consider Input: Passage: Although anthropologists worldwide refer to Tylor's definition of culture, in the 20th century "culture" emerged as the central and unifying concept of American anthropology, where it most commonly refers to the universal human capacity to classify and encode human experiences symbolically, and to communicate symbolically encoded experiences socially.[citation needed] American anthropology is organized into four fields, each of which plays an important role in research on culture: biological anthropology, linguistic anthropology, cultural anthropology, and archaeology.

Output: Who's definition of culture did anthropologists reject?

Input: Consider Input: Passage: Lions are said to inhabit the mountains of the Gash-Barka Region. There is also a small population of elephants that roam in some parts of the country. Dik-diks can also be found in many areas. The endangered African wild ass can be seen in Denakalia Region. Other local wildlife include bushbucks, duikers, greater kudus, klipspringers, African leopards, oryxs and crocodiles., The spotted hyena is widespread and fairly common. Between 1955 and 2001 there were no reported sightings of elephant herds, and they are thought to have fallen victim to the war of independence. In December 2001 a herd of about 30, including 10 juveniles, was observed in the vicinity of the Gash River. The elephants seemed to have formed a symbiotic relationship with olive baboons, with the baboons using the water holes dug by the elephants, while the elephants use the tree-top baboons as an early warning system.

Output: Where are African leopards predominantly found?

Input: Consider Input: Passage: Expansion of Highbury was restricted because the East Stand had been designated as a Grade II listed building and the other three stands were close to residential properties. These limitations prevented the club from maximising matchday revenue during the 1990s and first decade of the 21st century, putting them in danger of being left behind in the football boom of that time. After considering various options, in 2000 Arsenal proposed building a new 60,361-capacity stadium at Ashburton Grove, since named the Emirates Stadium, about 500 metres south-west of Highbury. The project was initially delayed by red tape and rising costs, and construction was completed in July 2006, in time for the start of the 200607 season. The stadium was named after its sponsors, the airline company Emirates, with whom the club signed the largest sponsorship deal in English football history, worth around 100 million; some fans referred to the ground as Ashburton Grove, or the Grove, as they did not agree with corporate sponsorship of stadium names. The stadium will be officially known as Emirates Stadium until at least 2028, and the airline will be the club's shirt sponsor until the end of the 201819 season. From the start of the 201011 season on, the stands of the stadium have been officially known as North Bank, East Stand, West Stand and Clock end.
Output: What was the East Stand of Highbury close to?
