Task: Question Generation
Input (English): Context_1 : The International Radiotelephony Spelling Alphabet, commonly known as the ICAO phonetic alphabet, sometimes called the NATO phonetic alphabet or spelling alphabet and the ITU radiotelephonic or phonetic alphabet, is the most widely used radiotelephonic spelling alphabet. Although often called "phonetic alphabets", spelling alphabets are unrelated to phonetic transcription systems such as the International Phonetic Alphabet. Instead, the International Civil Aviation Organization (ICAO) alphabet assigned codewords acrophonically to the letters of the English alphabet, so that critical combinations of letters and numbers are most likely to be pronounced and understood by those who exchange voice messages by radio or telephone, regardless of language differences or the quality of the communication channel. Context_2 : The Syriac alphabet is a writing system primarily used to write the Syriac language from the 1st century AD. It is one of the Semitic abjads descending from the Aramaic alphabet through the Palmyrene alphabet, and it shares similarities with the Phoenician, Hebrew, Arabic and the traditional Mongolian scripts. Context_3 : Hausa ( ) ("Yaren Hausa" or "Harshen Hausa") is the Chadic language (a branch of the Afroasiatic language family) with the largest number of speakers, spoken as a first language by more than 70 million people, and as a second language by another 40 to 50 million or more. Originally the language of the Hausa people stretching across southern Niger and northern Nigeria, it has developed into a lingua franca across much of western Africa for purposes of trade. In the 20th and 21st centuries, it has become more commonly published in print and online. Context_4 : The Uyghur Latin alphabet (, "Уйғур Латин Йезиқи, Uyghur Latin Yëziqi, ULY") is an auxiliary alphabet for the Uyghur language based on the Latin script. Uyghur is primarily written in an Arabic alphabet and sometimes in a Cyrillic alphabet. Context_5 : Inuktitut Braille is a proposed braille alphabet of the Inuktitut language based on Inuktitut syllabics. Unlike syllabics, it is a true alphabet, with separate letters for consonants and vowels, though vowels are written before the consonants they follow in speech. It was published in 2012 by Tamara Kearney, Manager of Braille Research and Development at the Commonwealth Braille and Talking Book Cooperative. The book ᐃᓕᐊᕐᔪᒃ ᓇᓄᕐᓗ "The Orphan and the Polar Bear" was the first (and perhaps only) work transliterated into Inuktitut Braille. Context_6 : The Modern Filipino alphabet (Filipino: "Makabagong alpabetong Filipino" ), otherwise known as the Filipino alphabet (Filipino: "alpabetong Filipino" ), is the alphabet of the Filipino language, the official national language and one of the two official languages of the Philippines. The Modern Filipino alphabet is made up of 28 letters, which includes the entire 26-letter set of the ISO basic Latin alphabet, the Spanish "Ñ" and the "Ng" digraph of Tagalog. It replaced the Pilipino alphabet of the Fourth Republic. Today, the Modern Filipino alphabet may also be used as the alphabet for all autochthonous languages of the Philippines and in writing Chavacano, a Spanish-derived creole. Context_7 : Boko (or bookoo) is a Latin-script alphabet used to write the Hausa language. The first boko was devised by Europeans in the early 19th century, and developed in the early 20th century by the British (mostly) and French colonial authorities. It was made the official Hausa alphabet in 1930. Since the 1950s boko has been the main alphabet for Hausa. Arabic script ("ajami") is now only used in Islamic schools and for Islamic literature. Since the 1980s, Nigerian boko has been based on the Pan-Nigerian alphabet. Context_8 : Hangul ( ; from Korean "hangeul" 한글 ] ), the Korean alphabet, is the alphabet that has been used to write the Korean language since the 15th century. It was created in 1443 under King Sejong the Great during the Joseon Dynasty. Today, the alphabet is the official script of both South Korea and North Korea, and co-official in the Yanbian Korean Autonomous Prefecture and Changbai Korean Autonomous County of China's Jilin Province. In South Korea, hangul is primarily used to write the Korean language, as using hanja (Chinese characters) in typical Korean writing fell out of common usage during the late 1990s. Context_9 : The Sogdian alphabet was originally used for the Sogdian language, a language in the Iranian family used by the people of Sogdia. The alphabet is derived from Syriac, the descendant script of the Aramaic alphabet. The Sogdian alphabet is one of three scripts used to write the Sogdian language, the others being the Manichaean alphabet and the Syriac alphabet. It was used throughout Central Asia, from the edge of Iran in the west, to China in the east, from approximately 100–1200 A.D. Context_10 : Adventure Game Studio (acronym AGS) is an open source development tool that is primarily used to create graphic adventure games. It is aimed at intermediate-level game designers, and combines an Integrated development environment (IDE) for setting up most aspects of the game with a scripting language based on the C language to process the game logic. fact_1 : Boko (or bookoo) is a Latin-script alphabet used to write the Hausa language. fact_2 : Hausa ( ) ("Yaren Hausa" or "Harshen Hausa") is the Chadic language (a branch of the Afroasiatic language family) with the largest number of speakers, spoken as a first language by more than 70 million people, and as a second language by another 40 to 50 million or more. fact_3 :  Originally the language of the Hausa people stretching across southern Niger and northern Nigeria, it has developed into a lingua franca across much of western Africa for purposes of trade. Answer: across much of western Africa
Output (English): Where was the language based on the Boko alphabet primarily used?
