question: On 13 June 1990, the East German military officially began dismantling the Wall, beginning in Bernauer Strae and around the Mitte district. From there, demolition continued through Prenzlauer Berg/Gesundbrunnen, Helligensee and throughout the city of Berlin until that December 1990. According to estimates by the border troops, a total of around 1.7 million tonnes of building rubble was produced by the demolition. Unofficially, the demolition of the Bornholmer Strae began because of construction work on the railway. This involved a total of 300 GDR border guards and - after 3 October 1990 - 600 Pioneers of the Bundeswehr. These were equipped with 175 trucks, 65 cranes, 55 excavators and 13 bulldozers. Virtually every road that was severed by the Berlin Wall, every road that once linked from West Berlin to East Berlin, was reconstructed and reopened by 1 August 1990. In Berlin alone, 184 km of wall, 154 km border fence, 144 km signal systems and 87 km barrier ditches were removed. What remained were six sections that were to be preserved as a memorial. Various military units dismantled the Berlin/Brandenberg border wall, completing the job in November 1991. Painted wall segments with artistically valuable motifs were put up for auction in 1990 in Berlin and Monte Carlo.
Answer this question: How many different components (including ditches and signal systems) were removed in Berlin alone?
answer: 4

question: The Dolphins, still looking for their first win of the year, stayed at home for a Week 3 match-up with the Tennessee Titans. Miami drew first blood in the first quarter with kicker Olindo Mare kicking a 40-yard field goal. In the second quarter, the Dolphins got a bit of a scare as Titans QB Kerry Collins completed a 27-yard pass to TE Bo Scaife for a touchdown and the lead. In the third quarter, Miami reclaimed the lead with QB Daunte Culpepper getting a touchdown on a 5-yard scramble. However, the Titans didn't go down quietly, as kicker Rob Bironas kicked a 22-yard field goal for Tennessee, putting the game in a 10-10 tie. Fortunately, in the fourth quarter, Mare finally helped Miami get win #1 with a 39-yard field goal.
Answer this question: How many more yards did Mare have compared with Bironas?
answer: 57

question: Although multinational corporations dominate Ireland's export sector, exports from other sources also contribute significantly to the national income. The activities of multinational companies based in Ireland have made it one of the largest exporters of pharmaceutical agents, medical devices and software-related goods and services in the world. Ireland's exports also relate to the activities of large Irish companies and exports of mineral resources: Ireland is the seventh largest producer of zinc concentrates, and the twelfth largest producer of lead concentrates. The country also has significant deposits of gypsum, limestone, and smaller quantities of copper, silver, gold, barite, and dolomite. Tourism in Ireland contributes about 4% of GDP and is a significant source of employment. Other goods exports include agri-food, cattle, beef, dairy products, and aluminum. Ireland's major imports include data processing equipment, chemicals, petroleum and petroleum products, textiles, and clothing. Financial services provided by multinational corporations based at the Irish Financial Services Centre also contribute to Irish exports. The difference between exports and imports resulted an annual trade surplus of 43.9 billion in 2010, which is the highest trade surplus relative to GDP achieved by any EU member state. The EU is by far the country's largest trading partner, accounting for 57.9% of exports and 60.7% of imports. The United Kingdom is the most important trading partner within the EU, accounting for 15.4% of exports and 32.1% of imports. Outside the EU, the United States accounted for 23.2% of exports and 14.1% of imports in 2010.
Answer this question: How many percent of Ireland's exports do not go to the EU?
answer:
42.1
