TASK DEFINITION: Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.
PROBLEM: Context: In the present study, we tested the hypothesis that having migraine in middle age is related to late-life parkinsonism and a related disorder, restless legs syndrome (RLS), also known as Willis-Ekbom disease (WED). The AGES-Reykjavik cohort (born 1907-1935) has been followed since 1967. Headaches were classified based on symptoms assessed in middle age. From 2002 to 2006, 5,764 participants were reexamined to assess symptoms of parkinsonism, diagnosis of Parkinson disease (PD), family history of PD, and RLS/WED. Subjects with midlife migraine, particularly migraine with aura (MA), were in later life more likely than others to report parkinsonian symptoms (odds ratio [OR]MA = 3.6 [95% CI 2.7-4.8]) and diagnosed PD (ORMA = 2.5 [95% CI 1.2-5.2]). Women with MA were more likely than others to have a parent (ORMA = 2.26 [95% CI 1.3-4.0]) or sibling (ORMA = 1.78 [95% CI 1.1-2.9]) with PD. Late-life RLS/WED was increased for headache generally. Associations were independent of cardiovascular disease and MRI-evident presumed ischemic lesions. These findings suggest there may be a common vulnerability to, or consequences of, migraine and multiple indicators of parkinsonism. Additional genetic and longitudinal observational studies are needed to identify candidate pathways that may account for the comorbid constellation of symptoms. 
 Question: Willis-Ekbom disease is also known as?

SOLUTION: restless legs syndrome

PROBLEM: Context: In the county, the population was spread out with 23.20% under the age of 18, 7.70% from 18 to 24, 27.00% from 25 to 44, 28.00% from 45 to 64, and 14.10% who were 65 years of age or older. The median age was 40 years. For every 100 females, there were 97.00 males. For every 100 females age 18 and over, there were 96.40 males. 
 Question: Which age group had the least people?

SOLUTION: 18 to 24

PROBLEM: Context: This article needs an improved plot summary. (November 2015) Sidhu (Akshay Kumar) is a lowly vegetable cutter at a roadside food stall in the Chandni Chowk section of Delhi, who consults astrologers, tarot card readers, and fake fakirs despite his foster father Dada's (Mithun Chakraborty) exhortations. When two strangers from China claim him as a reincarnation of war hero 'Liu Shen' and take him to China, Sidhu, encouraged by trickster Chopstick (Ranvir Shorey), believes he will be feted as a hero, unaware of his own recruitment to assassinate the smuggler Hojo (Gordon Liu). Sidhu travels to China with Chopstick. Along the way he meets Sakhi (Deepika Padukone), the Indian-Chinese spokesmodel known as Ms. Tele Shoppers Media, or Ms. TSM, who also appears in China. Her twin sister Suzy, known as the femme fatale Meow Meow, works for Hojo, not knowing Hojo tried to kill her father, Inspector Chiang (Roger Yuan). Sidhu, through a series of accidents, initially eludes Hojo, but Hojo eventually exposes him as a fraud. Thereupon Hojo kills Dada, and Sidhu is beaten and urinated on by Hojo. Injured and disgraced Sidhu vows revenge. He thereafter encounters an amnesiac vagrant, whom he later identifies to Sakhi as Inspector Chiang. Chiang later recovers his memory and trains Sidhu in kung fu. When Hojo again meets with Sidhu, Suzy injures Chiang; but upon seeing Sakhi, betrays Hojo. Sidhu fights Hojo in single combat, eventually using a modified vegetable-cutting technique to overwhelm him. In the aftermath, Sidhu opens a vegetable stall in China, but is recruited to fight for some African pygmies. The film thereupon concludes with the announcement "To be Continued Chandni Chowk to Africa". 
 Question: What do two strangers from China claim Sidhu as reincarnated?

SOLUTION:
liu shen
