[EX Q]: Context: With only four days until the bar exam, an utterly unprepared law intern, Rick Robinson (Ben Gourley), is given a rare opportunity to score points with his boss, Maxwell McAllister (Rutger Hauer) and without thinking, commits to a favor he cannot afford. Rick soon finds himself stuck in a grueling cross country road trip driving a rundown U-Haul truck carrying all his boss's worldly possessions. To make matters worse, he is left in charge of Mr. McAllister's bratty Hollywood-bound niece Michelle (Mila Kunis) and her out-of-control pet pig. The trip from Miami to Los Angeles meets several snags. The truck breaks down on a backwoods road in the deep South, and Rick's clothes are burned by the hillbilly family providing them refuge for the night. Later, another breakdown results in Rick being knocked unconscious. He is rescued by a peculiar hitchhiker called Orlie (Jon Heder), who finds a motel room for him and Michelle. Orlie asks to accompany Rick and Michelle, and is accepted, as Rick believes he owes him a favor for his rescue. Michelle takes a shine to Orlie, and they proceed to have fun at Rick's expense. After Orlie forces Rick into an unusual encounter in a fast food restaurant lavatory, Rick decides to leave him behind. He and Michelle grow closer to one another, following a stop at a Texas beach. Rick permits Michelle to drive, despite the insurance liability, due to fatigue. He wakes to find Michelle has taken them to Wichita, Kansas and Rick's home. Consequently, Rick is forced into a painful confrontation with his mentally ill father, an experience for which Michelle apologizes. They grow even closer as Michelle relates her life growing up. The pair travel to Colorado, where the truck runs out of gas. A semi in which Orlie is traveling as a passenger comes to their aid. Following a stop in a small town, the truck (and Michelle's pig) is stolen by men working for local crime boss "The Lady" (Billy Drago). The Lady forces Rick and Orlie to fight in a cage match before he returns the truck, impressed by the show they put on. Crossing into Utah, Orlie spots a landscape that matches a drawing in his notebook. He believes that he has switched bodies as some past moment when he was near death, and believes that the person now occupying his body will arrive here. A switch can then take place. Orlie leaves Rick and Michelle, telling them to keep going. As the window for Rick to safely arrive back in Miami for the bar exam narrows, he rejects Michelle's assertions that there is something special between them. Rick drives straight to Los Angeles, arriving in Malibu where Mr. McAllister is waiting for them at his beachside property. He states that Rick has arrived late, but does not appear overtly concerned. Realizing he must hurry to fly back to Miami, Rick rushes to the taxi McAllister has arranged for him, leaving Michelle asleep in the truck. At the airport security checkpoint, Rick realizes he is making a terrible mistake as he observes the Polaroid photos Michelle has snapped throughout their trip. Knowing he is meant to be with Michelle, he scrambles out of the airport and returns to Malibu. Finding Mr. McAllister, Rick confesses his feelings for Michelle. McAllister, having heard similar sentiments from Michelle regarding Rick, thanks him for returning and asks him to take care of her. McAllister adds that his law firm will be opening a Los Angeles branch. The movie ends as Rick reunites with Michelle on the beach, and a man approaches Orlie back in Utah. 
 Question: Where is Rick helping the niece move from?

[EX Q]: 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?
[EX A]: restless legs syndrome

[EX Q]: Context: Young people frequently say that they want to exercise, but they just can't find the time. The solution just might be in-office interval training. Recent studies show that very short but intense exercise rapidly builds and maintains fitness and health, even when the workout is only a few minutes long. Work the stairs You can complete an excellent, effective -- and very brief -- workout in an office stairwell, says Martin Gibala, a professor of kinesiology at McMaster University in Canada and an expert on interval training. For a study that he and his colleagues presented earlier this year, they asked 12 out-of-shape women in their 20s to warm up for two minutes by slowly walking up and down stairs in a campus office building. They completed three of these abbreviated stair workouts per week for six weeks. By the end, their aerobic fitness had improved substantially, the researchers reported, by about as much as if they had been running or cycling each week for hours. Fidget your way to fitness. Parents and teachers may once have urged you to sit still, but wiggling, tapping your toes, standing briefly, and otherwise fidgeting as much as possible at your desk is in fact good for your body. In one recent study, college students showed healthier blood flow in their lower legs if they fidgeted than if they did not. Even better, a 2008 study found that among office workers, those who frequently fidgeted burned as many as 300 calories more each day than those who resolutely stayed still.
