Instructions: In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Input: Question: Which group ruled the area for a longer period of time, the Arabs or the Byzantines? Passage 1:Anomocephaloidea is a clade (evolutionary grouping) of anomodont therapsids that existed in Gondwana during the Middle Permian and includes two species, Anomocephalus africanus from South Africa and Tiarajudens eccentricus from Brazil, both of which are characterized by large body size and teeth that fit tightly together or occlude. Anomocephaloidea is among the most basal groups of anomodonts, the other being Venyukovioidea, which differs in being a Laurasian clade of mostly small-bodied species. Anomocephaloidea was named in 2011 with the discovery of Tiarajudens; Anomocephalus had been known since 1999, but was unique among anomodonts until Tiarajudens was described. Both Anomocephalus and Tiarajudens were herbivores, although the latter possessed a pair of saber-like canine teeth that may have been used in display or combat with other individuals of the same species. Although Anomocephaloidea was short-lived and had a limited geographic distribution, it was part of a larger evolutionary radiation of anomodonts in the Middle Permian characterized by the evolution of a diverse array of new morphological characteristics and ecological roles, and that would later lead to the rise of Dicynodontia, the largest clade within Anomodontia and one of the most successful groups of tetrapods in the Permian.
Passage 2:Despite its name, the coalition was on the right wing of French politics; for a long time, the French republican right has refused to call itself "right" since the right-wing in France has historically been associated with monarchism (this practice is known as sinistrisme). It was subsidised by French employers, who saw in it the best defense against Communism and the defender of economic liberalism, in a context marked by various nationalizations supported by the French Communist Party (PCF), the French Section of the Workers' International (SFIO) and the Gaullist movement. Employers conceived the RGR as such until at least the 1951 creation of the National Centre of Independents and Peasants (CNIP) gathering independent conservative deputies. During the 1956 legislative campaign, it became a political party led by Edgar Faure and Radicals who refused to join the Republican Front coalition.
Passage 3:The first permanent Arab settlement on Sicily occurred in 827, but it was not until Taormina fell in 902 that the entire island fell under their sway, though Rometta held out until 965. In that year the Kalbids established the independence of their emirate from the Fatimid Caliphate. In 1061 the first Norman liberators took Messina, and by 1071 Palermo and its citadel (1072) were captured. In 1091 Noto fell to the Normans, and the conquest was complete. Malta fell later that year, though the Arab administration was kept in place, marking the final chapter of this period. The conquests of the Normans established Roman Catholicism firmly in the region, where Eastern Christianity had been prominent during the time of Byzantine rule and even remained significant during Islamic period. Widespread conversion ensued, leading to the disappearance of Islam in Sicily by the 1280s. In 1245, Muslim Sicilians were deported to the settlement of Lucera, by order of Holy Roman Emperor Frederick II. In 1300, Giovanni Pipino da Barletta, count of Altamura, seized Lucera and exiled or sold into slavery its population, bringing an end to the medieval Muslim presence in Italy.
