input: Please answer the following: I know that the answer to the question "What is pinyin?" is in "Chinese character dictionaries often allow users to locate entries in several ways. Many Chinese, Japanese, and Korean dictionaries of Chinese characters list characters in radical order: characters are grouped together by radical, and radicals containing fewer strokes come before radicals containing more strokes (radical-and-stroke sorting). Under each radical, characters are listed by their total number of strokes. It is often also possible to search for characters by sound, using pinyin (in Chinese dictionaries), zhuyin (in Taiwanese dictionaries), kana (in Japanese dictionaries) or hangul (in Korean dictionaries). Most dictionaries also allow searches by total number of strokes, and individual dictionaries often allow other search methods as well.". Can you tell me what it is?

Please answer this: I know that the answer to the question "What made the band sign with John Reid?" is in "In 1975, the band left for a world tour with each member in Zandra Rhodes-created costumes and accompanied with banks of lights and effects. They toured the US as headliners, and played in Canada for the first time. In September, after an acromonious split with Trident, the band negotiated themselves out of their Trident Studios contract and searched for new management. One of the options they considered was an offer from Led Zeppelin's manager, Peter Grant. Grant wanted them to sign with Led Zeppelin's own production company, Swan Song Records. The band found the contract unacceptable and instead contacted Elton John's manager, John Reid, who accepted the position.". Can you tell me what it is?

Problem: I know that the answer to the question "Why do people invent new Chinese characters?" is in "The total number of Chinese characters from past to present remains unknowable because new ones are developed all the time for instance, brands may create new characters when none of the existing ones allow for the intended meaning. Chinese characters are theoretically an open set and anyone can create new characters, though such inventions are rarely included in official character sets. The number of entries in major Chinese dictionaries is the best means of estimating the historical growth of character inventory.". Can you tell me what it is?

A: none of the existing ones allow for the intended meaning

Problem: Given the question: I know that the answer to the question "What was the ultimate fate of the Northland Center?" is in "After World War II Hudson's realized that the limited parking space at its downtown skyscraper would increasingly be a problem for its customers. The solution in 1954 was to open the Northland Center in nearby Southfield, just beyond the city limits. It was the largest suburban shopping center in the world, and quickly became the main shopping destination for northern and western Detroit, and for much of the suburbs. By 1961 the downtown skyscraper accounted for only half of Hudson's sales; it closed in 1986. The Northland Center Hudson's, rebranded Macy's in 2006 following acquisition by Federated Department Stores, was closed along with the remaining stores in the center in March 2015 due to the mall's high storefront vacancy, decaying infrastructure, and financial mismanagement.".
