Input: Consider Input: Carthage was a Phoenician colony on the coast of Tunisia. Carthaginian culture came into contact with the Greeks through Punic colonies in Sicily and through their widespread Mediterranean trade network. While the Carthaginians retained their Punic culture and language, they did adopt some Hellenistic ways, one of the most prominent of which was their military practices. In 550 BCE, Mago I of Carthage began a series of military reforms which included copying the army of Timoleon, Tyrant of Syracuse. The core of Carthage's military was the Greek-style phalanx formed by citizen hoplite spearmen who had been conscripted into service, though their armies also included large numbers of mercenaries. After their defeat in the first Punic war, Carthage hired a Spartan mercenary captain, Xanthippus of Carthage to reform their military forces. Xanthippus reformed the Carthaginian military along Macedonian army lines.

Output: Carthage was on the coast of what country?


Input: Consider Input: After the grant of the royal charter it had become known as the Royal Institute of British Architects in London, eventually dropping the reference to London in 1892. In 1934, it moved to its current headquarters on Portland Place, with the building being opened by King George V and Queen Mary.

Output: What caused the change of the Institute's name?


Input: Consider Input: Roofs are traditionally constructed from Alpine rocks such as pieces of schist, gneiss or slate. Such chalets are typically found in the higher parts of the valleys, as in the Maurienne valley in Savoy, where the amount of snow during the cold months is important. The inclination of the roof cannot exceed 40%, allowing the snow to stay on top, thereby functioning as insulation from the cold. In the lower areas where the forests are widespread, wooden tiles are traditionally used. Commonly made of Norway spruce, they are called "tavaillon". The Alpine regions are multicultural and linguistically diverse. Dialects are common, and vary from valley to valley and region to region. In the Slavic Alps alone 19 dialects have been identified. Some of the French dialects spoken in the French, Swiss and Italian alps of Aosta Valley derive from Arpitan, while the southern part of the western range is related to Old Provençal; the German dialects derive from Germanic tribal languages. Romansh, spoken by two percent of the population in southeast Switzerland, is an ancient Rhaeto-Romanic language derived from Latin, remnants of ancient Celtic languages and perhaps Etruscan.


Output: What are roofs traditionally constructed from?
