Input: Read this: The Tibetan name for their land, Bod , means "Tibet" or "Tibetan Plateau", although it originally meant the central region around Lhasa, now known in Tibetan as U. The Standard Tibetan pronunciation of Bod, [p], is transcribed Bho in Tournadre Phonetic Transcription, Bo in the THL Simplified Phonetic Transcription and Poi in Tibetan pinyin.

QUES: East Tucson is relatively new compared to other parts of the city, developed between the 1950s and the 1970s,[citation needed] with developments such as Desert Palms Park. It is generally classified as the area of the city east of Swan Road, with above-average real estate values relative to the rest of the city.

Question: In 2003 the FA took the decision to permanently use the new Wembley for semi-finals to recoup debts in financing the new stadium. This was controversial, with the move seen as both unfair to fans of teams located far from London, as well as taking some of the prestige away from a Wembley final. In defending the move, the FA has also cited the extra capacity Wembley offers, although the 2013 fixture between Millwall and Wigan led to the unprecedented step of placing 6,000 tickets on sale to neutral fans after the game failed to sell out. A fan poll by The Guardian in 2013 found 86% opposition to Wembley semi-finals.
Try to answer this question if possible: Why did the FA decide to not use the new Wembley in 2003?
Answer: unanswerable

Problem: Around the sixth century AD, a tribe of Slavs arrived in a portion of Central Europe. According to legend they were led by a hero named Cech, from whom the word "Czech" derives. The ninth century brought the state of Great Moravia, whose first ruler (Rastislav of Moravia) invited Byzantine ruler Michael III to send missionaries in an attempt to reduce the influence of East Francia on religious and political life in his country. These missionaries, Constantine and Methodius, helped to convert the Czechs from traditional Slavic paganism to Christianity and established a church system. They also brought the Glagolitic alphabet to the West Slavs, whose language was previously unwritten. This language, later known as Proto-Czech, was beginning to separate from its fellow West Slavic hatchlings Proto-Slovak, Proto-Polish and Proto-Sorbian. Among other features, Proto-Czech was marked by its ephemeral use of the voiced velar fricative consonant (//) and consistent stress on the first syllable.
When did Rastislav of Moravia arrive in Glagolitic?
