Teacher: Now, understand the problem? Solve this instance: Question: How many Roman monuments are located in Mérida, Spain? Passage 1:In addition to Shahrbanu, the historian Al-Masudi provides the names of four other children of Yazdegerd III; two sons, namely Peroz and Bahram, and two daughters, Adrag and Mardawand. While it was historically recorded that her brothers had escaped to the Tang emperor of China, Islamic traditions state that Shahrbanu's sisters were captured alongside her. One allegedly married Abdullah, son of the Caliph Umar, and became the mother of his son Salim, while another married Muhammad, son of the Caliph Abu Bakr, and became the mother of his son Qasim. Further alleged siblings have also been attributed to Shahrbanu, including Ghayanbanu, who was her full sister, Izdundad, who married the Jewish exilarch Bostanai, and Mihrbanu, who married Chandragupta, the Indian king of Ujjain.
 Passage 2:The regiment embarked for the West Indies in October 1826. It was initially based in Trinidad but moved to Barbados in January 1828, Antigua in January 1830 and Demerara and Berbice in February 1833. It embarked for home in March 1837. It returned to India in 1842 and saw action in Central India during the Indian Rebellion. It formed part of the force led by Major-General Sir Hugh Rose which besieged and captured Jhansi Fort in April 1858: four Victoria Crosses were awarded to members of the regiment for this operation. It returned home in August 1859 and was deployed to Gibraltar in 1864 and then went on to Mauritius in 1867 before returning to the Cape of Good Hope in 1870. It returned home in 1875 and then embarked for Bermuda in 1880.
 Passage 3:Mérida has been populated since prehistoric times as demonstrated by a prestigious hoard of gold jewellery that was excavated from a girl's grave in 1870. Consisting of two penannular bracelets, an armlet and a chain of six spiral wire rings, it is now preserved at the British Museum. The town was founded in 25 BC, with the name of Emerita Augusta (meaning the veterans – discharged soldiers – of the army of Augustus, who founded the city; the name Mérida is an evolution of this) by order of Emperor Augustus, to protect a pass and a bridge over the Guadiana river. Emerita Augusta was one of the ends of the Vía de la Plata (Silver Way), a strategic Roman Route between the gold mines around Asturica Augusta and the most important Roman city in the Iberian Peninsula. The city became the capital of Lusitania province, and one of the most important cities in the Roman Empire. Mérida preserves more important ancient Roman monuments than any other city in Spain, including a triumphal arch and a theatre.
