Problem: 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.

How many more excavators was the construction/demolition equipped with compared to bulldozers?
Answer: 42

Problem: In 1616 the Venetians besieged Farra and Gradisca, and the archduke attacked from Gorizia and Lucinico. With three large culverins, four guns and three small culverins, Farra repulsed the enemy artillery with heavy losses. The Venetians launched another futile assault before Giustiniani lifted the siege and retreated to Mariano. In September, Johan Ernst van Nassau-Siegen agreed to raise 3,000 men from the Dutch Republic for Venetian service. They arrived in May 1617, followed six months later by another 2,000 . Spanish support was blocked at sea by a flotilla of 12 Dutch and 10 English warships and on land by the war in Mantua. Although Archduke Ferdinand had only 4,000 soldiers to defend Gradisca, he received military, political and financial support from the Spanish as part of a larger agreement: Philip agreed to fight the Venetians and support Ferdinand as the next Holy Roman Emperor in return for the cession of Alsace, Finale Ligure and Piombino. This led to a negotiated settlement between Ferdinand and the Venetians in which many Uskok pirates were executed or exiled, and a permanent Austrian garrison was installed in Senj.

How many more Dutch warships were there than English?
Answer: 2

Problem: The 24th Infantry was re-instituted in 1995 and assigned to the 1st Brigade, 25th Infantry Division in Fort Lewis, Washington. The regiment served in the Iraq War from 2004 to 2005, and was decorated for its service. In 2006, during a re-organization of the Army, the regiment was re-flagged; however, the 1st Battalion was not included, and so it alone retains the regimental designation and carries on its legacy. It is now part of the 1st Brigade Combat Team , 25th Infantry Division at Fort Wainwright, Alaska.

How many years did the regiment serve in the Iraq War?
Answer: 1

Problem: The Japanese began to catch gray whales beginning in the 1570s. At Kawajiri, Nagato Province, 169 gray whales were caught between 1698 and 1889. At Tsuro, Japan, Shikoku, 201 were taken between 1849 and 1896. Several hundred more were probably caught by American and European whalemen in the Sea of Okhotsk from the 1840s to the early 20th century. Whalemen caught 44 with nets in Japan during the 1890s. The real damage was done between 1911 and 1933, when Japanese whalemen killed 1,449 after Japanese companies established several whaling stations on Korean Peninsula and on Chinese coast such as near the Daya bay and on Hainan Island. By 1934, the western gray whale was near extinction. From 1891 to 1966, an estimated 1,8002,000 gray whales were caught, with peak catches of between 100 and 200 annually occurring in the 1910s.

How many grey whales were caught per year, on average, from 1891 to 1966 based on the largest estimate?
Answer:
26.66
