Question: Question: When was the Empire that dominated the People of Totanac ethnicity formed? Passage:Totonacapan refers to the historical extension where the Totonac people of Mexico dominated, as well as to a region in the modern states of Veracruz and Puebla. The historical territory was much larger than the currently named region, extending from the Cazones River in the north to the Papaloapan River in the south and then west from the Gulf of Mexico into what is now the Sierra Norte de Puebla region and into parts of Hidalgo. When the Spanish arrived, the Totonac ethnicity dominated this large region, although they themselves were dominated by the Aztec Empire. For this reason, they allied with Hernán Cortés against Tenochtitlán. However, over the colonial period, the Totonac population and territory shrank, especially after 1750 when mestizos began infiltrating Totonacapan, taking political and economic power. This continued into the 19th and 20th centuries, prompting the division of most of historical Totonacpan between the states of Puebla and Veracruz. Today, the term refers only to a region in the north of Veracruz were Totonac culture is still important. This region is home to the El Tajín and Cempoala archeological sites as well as Papantla, which is noted for its performance of the Danza de los Voladores.

Question: Question: Who was the founder of the railroad? Passage:The original train track through Irwindale were built by the Los Angeles and San Gabriel Valley Railroad. The Gold line uses the old right of way of the Los Angeles and San Gabriel Valley Railroad who built the first train tracks through Irwindale in 1887. The Los Angeles and San Gabriel Valley Railroad was founded in 1883, by James F. Crank with the goal of bringing a rail line to San Gabriel Valley from downtown Los Angeles. Los Angeles and San Gabriel Valley Railroad was sold on May 20, 1887 into the California Central Railway. In 1889 the rail line was consolidated into Southern California Railway Company. On Jan. 17, 1906 Southern California Railway was sold to the Atchison, Topeka and Santa Fe Railway and called the Pasadena Subdivision. Amtrak-Santa Fe ran the Southwest Chief and Desert Wind over this line through Irwindale, but relocated the Desert Wind to the Fullerton Line in 1986. The Santa Fe line served the San Gabriel Valley until 1994, when the 1994 Northridge earthquake weakened the bridge in Arcadia and the track was closed till the Gold line was built. The rail line crosses the San Gabriel River on a long girder bridge, then passes through the Santa Fe Dam Recreation Area (how it received its name). The rail line intersected the north end of the former SP Azusa Industrial Track at Irwindale (MP 118.2). Irwindale had a 6,165 foot rail siding that passed the Miller Brewing Company's Irwindale brewery. From there the tracks continued and crossed beneath Irwindale Avenue.

Question: Question: Was al-Muqaddasi from Gharjistan? Passage:The Abbasid-era geographers report that the town was the centre of a flourishing agricultural region, with a number of dependent suburbs such as Qasr-i Ahnaf. According to al-Muqaddasi, who wrote in ca. 980, the locals were kin of the people of Gharjistan, and the town was a dependency of the rulers, or Shirs, of Gharjistan. A section of the Harbiyya district of the Round city of Baghdad was named Marwrūdiyya () after the people from this city. The town continued to flourish under the Seljuk Empire, when the Seljuk ruler Ahmad Sanjar built the city a new wall, some 5,000 paces in circumference. The town and the surrounding area suffered during the constant conflicts between the Khwarazmshahs and the Ghurids in the late 12th century, and a battle was fought there between the Ghurid ruler Ghiyath al-Din Muhammad (r. 1163–1202) and his Khwarazmian rival Sultan Shah (r. 1172–1193) in 1190. Although the town appears to have escaped the destruction of Marw al-Shahijan by the Mongols, it fell into ruin under the Timurids and was largely abandoned.
