[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: Miles Monroe (Woody Allen), a jazz musician and owner of the "Happy Carrot" health-food store in 1973, is subjected to cryopreservation without his consent, and not revived for 200 years.[2] The scientists who revive him are members of a rebellion: 22nd-century America seems to be a police state, ruled by a dictator about to implement a secret plan known as the "Aries Project". The rebels hope to use Miles as a spy to infiltrate the Aries Project, because he is the only member of this society without a known biometric identity. The authorities discover the scientists' project, and arrest them. Miles escapes by disguising himself as a robot, and goes to work as a butler in the house of socialite Luna Schlosser (Diane Keaton). When Luna decides to have his head replaced with something more "aesthetically pleasing," Miles reveals his true identity to her, whereupon Luna threatens to give Miles to the authorities. In response, he kidnaps her and goes on the run, searching for the Aries Project. Miles and Luna fall in love, but Miles is captured and brainwashed into becoming a complacent member of the society, while Luna joins the rebellion. The rebels kidnap Miles and perform reverse-brainwashing, whereupon he remembers his past and joins their efforts. Miles becomes jealous when he catches Luna kissing the rebel leader, Erno Windt (John Beck), and she tells him that she believes in free love. Miles and Luna infiltrate the Aries Project, wherein they quickly learn that the national leader had been killed by a rebel bomb ten months previously. All that survives is his nose. Other members of the Aries Project, mistaking Miles and Luna for doctors, expect them to clone the leader from this single remaining part. Miles steals the nose and "assassinates" it by dropping it in the path of a road roller. After escaping, Miles and Luna debate their future together. He tells her that Erno will inevitably become as corrupt as the Leader. Miles and Luna confess their love for one another, but she claims that science has proven men and women cannot have meaningful relationships due to chemical incompatibilities. Miles dismisses this, saying that he does not believe in science, and Luna points out that he does not believe in God or political systems either. Luna asks Miles if there is anything he does believe in, and he responds with the line, "Sex and deathtwo things that come once in a lifetimebut at least after death you're not nauseous."[3] The film ends as the two embrace. 
 Question: Who catches onto the scientists' project?
[EX A]: the police or the authorities

[EX Q]: Context: When Earth formed 4.6 billion years ago, it would not have been called the water planet. There were no oceans then. In fact, there was no liquid water at all. Early Earth was too hot for liquid water to exist. Earths early years were spent as molten rock and metal. Over time, Earth cooled. The surface hardened to become solid rock. Volcanic eruptions, like the one in Figure 14.1, brought lava and gases to the surface. One of the gases was water vapor. More water vapor came from asteroids and comets that crashed into Earth. As Earth cooled still more, the water vapor condensed to make Earths first liquid water. At last, the oceans could start to form. Earths crust consists of many tectonic plates that move over time. Due to plate tectonics, the continents changed their shapes and positions during Earth history. As the continents changed, so did the oceans. About 250 million years ago, there was one huge land mass known as Pangaea. There was also one huge ocean called Panthalassa. You can see it in Figure 14.2. By 180 million years ago, Pangaea began to break up. The continents started to drift apart. They slowly moved to where they are today. The movement of the continents caused Panthalassa to break into smaller oceans. These oceans are now known as the Pacific, Atlantic, Indian, and Arctic Oceans. The waters of all the oceans are connected. Oceans cover more than 70 percent of Earths surface and hold 97 percent of its surface water. Its no surprise that the oceans have a big influence on the planet. The oceans affect the atmosphere, climate, and living things. Oceans are the major source of water vapor in the atmosphere. Sunlight heats water near the sea surface, as shown in Figure 14.3. As the water warms, some of it evaporates. The water vapor rises into the air, where it may form clouds and precipitation. Precipitation provides the freshwater needed by plants and other living things. Ocean water also absorbs gases from the atmosphere. The most important are oxygen and carbon dioxide. Oxygen is needed by living things in the oceans. Much of the carbon dioxide sinks to the bottom of the seas. Carbon dioxide is a major cause of global warming. By absorbing carbon dioxide, the oceans help control global warming. Coastal areas have a milder climate than inland areas. They are warmer in the winter and cooler in the summer. Thats because land near an ocean is influenced by the temperature of the oceans. The temperature of ocean water is moderate and stable. Why? There are two major reasons: 1. Water is much slower to warm up and cool down than land. As a result, oceans never get as hot or as cold as land. 2. Water flows through all the worlds oceans. Warm water from the equator mixes with cold water from the poles. The mixing of warm and cold water makes the water temperature moderate. Even inland temperatures are milder because of oceans. Without oceans, there would be much bigger temperature swings all over Earth. Temperatures might plunge hundreds of degrees below freezing in the winter. In the summer, lakes and seas might boil! Life as we know it could not exist on Earth without the oceans. The oceans provide a home to many living things. In fact, a greater number of organisms lives in the oceans than on land. Coral reefs, like the one in Figure 14.4, have more diversity of life forms than almost anywhere else on Earth. You know that ocean water is salty. But do you know why? How salty is it? Ocean water is salty because water dissolves minerals out of rocks. This happens whenever water flows over or through rocks. Much of this water and its minerals flow in rivers that end up in the oceans. Minerals dissolved in water form salts. When the water evaporates, it leaves the salts behind. As a result, ocean water is much saltier than other water on Earth. Have you ever gone swimming in the ocean? If you have, then you probably tasted the salts in the water. By
