Q: Passage: The site of the battle is located near U.S. Highway 56, about three miles east of Baldwin City, and is partially within Robert Hall Pearson Memorial Park, designated by the state of Kansas in honor of one of Brown and Shore's fighters who gave a handwritten account of the battle. Signs placed throughout the battle site point out where the battle began and ended. Efforts are underway to preserve both the Pearson Memorial Park and the Ivan Boyd Prairie Preserve across the road. In 1970, to commemorate the 100th anniversary of the founding of Baldwin City, Baker University professor and playwright Don Mueller and Phyllis E. Braun, Business Manager, produced a musical play entitled The Ballad Of Black Jack to tell the story of the events that led up to the battle. The Ballad Of Black Jack played as part of the city's Maple Leaf Festival from 1970-83 and again from 2001-05. It also played in nearby Lawrence in 1986 and in 2006 and 2007 as a part of Lawrence's Civil War On The Western Frontier program. In 2012 the National Park Service designated the battlefield a National Historic Landmark.
Question: When was the last time the Ballad of Black Jack was played as part of the city's Maple Leaf Festival?

Q: Passage: The screening suggests that in 2000, 19 percent of all newborn babies in Metropolitan France had at least one parent originating from one of the risk regions. The figure for 2007 was 28.45 percent, for 2010 31.5 percent, for 2012 34.44 percent, for 2013 35.7 percent, and for 2015 38.9 percent. These percentages vary widely among French regions; for example, in 2015, screening suggested that only 8.1% of children born in Brittany had a parent originating from a sickle-cell risk region, while 73.4% of children born in Ile-de-France (which includes Paris) did. The percentage for Ile-de-France was a significant increase from 54.2% in 2005. However, a 2014 story in Le Monde suggested that the testing figures for Ile-de-France were distorted by the practices of some hospitals in the region, which choose to test all babies whether or not they have parents with ancestry from an endemic sickle-cell region.
Question: What year did Metropolitan France have the highest number of newborns with at least one parent originating from a risk region?

Q: Passage: In the short term, the 1906 Dutch invasion in Bali, and its sequel in 1908, sealed the Dutch control of the island. The Dutch invasion however was followed closely by media coverage, and reports of the bloody conquest of the southern part of the island filtered to the West. The disproportion between the offense and harshness of the punitive actions was pointed out. The image of the Netherlands as a benevolent and responsible colonial power was seriously affected as a consequence. The Netherlands, also under criticism for their policies in Java, Sumatra and the eastern island, decided to make amends, and announced the establishment of an "Ethical policy". As a consequence, the Dutch in Bali turned students and protectors of Balinese culture and endeavored to preserve it in addition to their initial modernization role. Efforts were made at preserving Bali culture and at making it a "living museum" of classical culture, and in 1914, Bali was opened to tourism. The very harshness of the 1906 and 1908 military invasions thus paradoxically triggered an international uproar which contributed to the preservation of Bali's culture, to make the island one of the most popular tourist destinations today.
Question: When was the second Dutch invasion of Bali?
