question:
Context: The Caste War of Yucatan was a conflict that lasted from 1847 to 1901. It began with the revolt of native Maya people led by Maya chiefs Jacinto Pat and Cecilio Chi, against the population of European descent called "Yucatecos", who had political and economic control. A lengthy war ensued between the Yucateco forces in the north-west of the Yucatan and the independent Maya in the south-east. It officially ended with the occupation of the Maya capital of Chan Santa Cruz by the Mexican army in 1901, although skirmishes with villages and small settlements that refused to acknowledge Mexican control continued for over another decade. Adam Jones wrote: "This ferocious race war featured genocidal atrocities on both sides, with up to 200,000 killed." Because of the conflict, on November 24, 1902, Yucatan had a second territorial division when Porfirio Diaz decreed the creation of the Federal Territory of Quintana Roo, with capital in the port of Payo Obispo . In little more than half a century, Yucatan lost more than two thirds of its original territory. 
 Question: Who had control of the area after 1901?
answer:
mexican army

Context: Recent genome-wide association studies (GWAS) for Caucasians identified several allelic variants associated with increased risk of developing restless legs syndrome (RLS), also known as Willis-Ekbom disease. Although the pathogenic mechanisms of RLS are not entirely understood, it is becoming increasingly evident that many diseases such as RLS can be attributed to an epistasis. The study objectives were to evaluate whether the associations of RLS with all loci determined in previous GWAS for Caucasians can be replicated significantly for the Korean population and to elucidate whether an epistasis plays a role in the pathogenesis of RLS. DNA from 320 patients with RLS and 320 age- and sex-matched controls were genotyped for variants in the RLS loci. A significant association was found for rs3923809 and rs9296249 in BTBD9 (P < 0.0001 and P = 0.001, respectively); the odds ratio (OR) for rs3923809 was 1.61 (P < 0.0001) to 1.88 (P < 0.0001) and the OR for rs9296249 was 1.44 (P = 0.001) to 1.73 (P = 0.002), according to the model of inheritance. The OR for the interaction between rs3923809 in BTBD9 and rs4626664 in PTPRD was 2.05 (P < 0.0001) in the additive model, 1.80 (P = 0.002) in the dominant model and 2.47 (P = 0.004) in the recessive model. There was no significant association between genotypes of all tested single nucleotide polymorphisms and the mean value of serum iron parameters. Our results suggest that the role of BTBD9 in the pathogenesis of restless legs syndrome is more universal across populations than previously reported and more efforts should be focused on the role of epistasis in the genetic architecture of restless legs syndrome. 
 Question: Willis-Ekbom disease is also known as?
answer:
restless legs syndrome


question:
Context: 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: Which occurred first, the 100th anniversary of the founding of Baldwin City or the National Park Service designated the battlefield a National Historic Landmark?
answer:

the 100th anniversary
