Input: Article: The Alps are a source of minerals that have been mined for thousands of years. In the 8th to 6th centuries BC during the Hallstatt culture, Celtic tribes mined copper; later the Romans mined gold for coins in the Bad Gastein area. Erzberg in Styria furnishes high-quality iron ore for the steel industry. Crystals are found throughout much of the Alpine region such as cinnabar, amethyst, and quartz. The cinnabar deposits in Slovenia are a notable source of cinnabar pigments.

Now answer this question: What does Erzberd in Styria furnish?

Input: Article: The Shunga Empire or Shunga Empire was an ancient Indian dynasty from Magadha that controlled vast areas of the Indian subcontinent from around 187 to 78 BCE. The dynasty was established by Pushyamitra Shunga, after the fall of the Maurya Empire. Its capital was Pataliputra, but later emperors such as Bhagabhadra also held court at Besnagar, modern Vidisha in Eastern Malwa. Pushyamitra Shunga ruled for 36 years and was succeeded by his son Agnimitra. There were ten Shunga rulers. The empire is noted for its numerous wars with both foreign and indigenous powers. They fought battles with the Kalingas, Satavahanas, the Indo-Greeks, and possibly the Panchalas and Mathuras. Art, education, philosophy, and other forms of learning flowered during this period including small terracotta images, larger stone sculptures, and architectural monuments such as the Stupa at Bharhut, and the renowned Great Stupa at Sanchi. The Shunga rulers helped to establish the tradition of royal sponsorship of learning and art. The script used by the empire was a variant of Brahmi and was used to write the Sanskrit language. The Shunga Empire played an imperative role in patronizing Indian culture at a time when some of the most important developments in Hindu thought were taking place.

Now answer this question: What was the time span of the Shunga Empire?

Output: 187 to 78 BCE

Input: Article: Viking invasions began in the 9th century, followed by more permanent settlements, particularly along the east coast of Ireland, the west coast of modern-day Scotland and the Isle of Man. Though the Vikings were eventually neutralised in Ireland, their influence remained in the cities of Dublin, Cork, Limerick, Waterford and Wexford. England however was slowly conquered around the turn of the first millennium AD, and eventually became a feudal possession of Denmark. The relations between the descendants of Vikings in England and counterparts in Normandy, in northern France, lay at the heart of a series of events that led to the Norman conquest of England in 1066. The remnants of the Duchy of Normandy, which conquered England, remain associated to the English Crown as the Channel Islands to this day. A century later the marriage of the future Henry II of England to Eleanor of Aquitaine created the Angevin Empire, partially under the French Crown. At the invitation of a provincial king and under the authority of Pope Adrian IV (the only Englishman to be elected pope), the Angevins invaded Ireland in 1169. Though initially intended to be kept as an independent kingdom, the failure of the Irish High King to ensure the terms of the Treaty of Windsor led Henry II, as King of England, to rule as effective monarch under the title of Lord of Ireland. This title was granted to his younger son but when Henry's heir unexpectedly died the title of King of England and Lord of Ireland became entwined in one person.
