Q: Context: The film opens in Tokyo, where 27-year-old office worker Taeko Okajima, is planning to take a 10-day vacation. Having previously visited her sister's husband's farm in Yamagata. She had a good time there before, and has decided to go back again.As she prepares for her trip, her mind drifts back to her youth, when she was 10-years-old. After school lets out, almost all of Taeko's classmates have interesting places they are going to go to, but Taeko does not. When she brings this up to her family, they suggest that Taeko go with the family's Grandmother to a hot springs resort.Taeko eagerly goes with her Grandmother, but finds herself bored when all her Grandmother wishes to do is relax in their room. Taeko goes exploring the myriad baths in the resort by herself, but due to either the overwhelming beauty of one bath (or the heat of the baths), she passes out.While packing, she receives a call from her older sister whose husband owns the farm, and they have a laugh over the past incident.On her way to the train to the farm, Taeko passes by a fruit stand, and is reminded of when the family received a pineapple.This also happened during her 10th year, and she recalls how almost noone knew how to properly cut it. Her father decreed that it would not be touched until it was found out, and a few days later, one of Taeko's sister finds out. There is much eagerness once it is sliced into pieces, but slowly, the family quickly discerns they do not like its taste. Taeko attempts to stomach the pieces she has, and her sisters give her their pieces. In the end, the family concluded that the banana is the "king of fruits."Making it to the train station, Taeko also recalls more about the year 1966, when she was 10-years-old. With the popularity of the Beatles in full-swing, her sisters became enamored with the trends of the time. Her sister Nanako was in art school, and kept up with trends, including wearing a mini-skirt. Her other sister Yaeko had a small crush on an actress in a female acting troupe. However, while her sisters remember these things fondly, Taeko recalls she was too young to really get into these trends like her older sisters.One day after showing her Mother her grades, her Mother finds leftovers from her lunch, and expresses her disappointment in her daughter being picky, and not finishing her food. The next day at lunch, she is sitting next to a boy who is fine with finishing the radish and onion portion of his meal, but dislikes finishing his milk (per school rules, a student can only leave one item to be thrown away from their meal). Taeko offers to give him her radish and onions, and she'll finish his milk. The two quickly make a trade, but Taeko quickly finds that though she has no problems drinking milk, there's a bit too much for her to enjoy a second bowl.Afterwards, Taeko and several of her friends take part in a classroom debate. The topics cover everything from running in the halls, to handling leftovers. Not much is done regarding the issues, and there is much bickering and yelling.After remembering these things, the adult Taeko boards her train for the farm.Once aboard, her memories shift back to an encounter, where three girls from another class gigglingly inform her that a boy in their class named Hirota likes her. Taeko has no idea who Hirota, and her friends show her some graffiti near the school, showing Taeko and Hirota's name under an umbrella-like drawing. Her friends do some research, and find out that Hirota is a good pitcher for his classroom's baseball team.One day, both Taeko and Hirota's classes are pitted against each other in a baseball game.Hirota's female classmates eagerly chant that Taeko is watching, and Taeko's friends cheer for their own homeroom team, in defiance of the other girls. During the game, the cold gets to Takeko, and she rushes for the 
 Question: What city was Taeko traveling to?

A: yamagata.

Q: Context: Nuclear fission is the splitting of the nucleus of an atom into two smaller nuclei. This type of reaction releases a great deal of energy from a very small amount of matter. For example, nuclear fission of a tiny pellet of uranium-235, like the one pictured in Figure 11.11, can release as much energy as burning 1,000 kilograms of coal! Nuclear fission of uranium-235 can be represented by this equation: 235 92 U + 1 141 Neutron !92 36 Kr + 56 Ba + 3 Neutrons + Energy As shown in Figure 11.12, the reaction begins when a nucleus of uranium-235 absorbs a neutron. This can happen naturally or when a neutron is deliberately crashed into a uranium nucleus in a nuclear power plant. In either case, the nucleus of uranium becomes very unstable and splits in two. In this example, it forms krypton-92 and barium-141. The reaction also releases three neutrons and a great deal of energy. The neutrons released in this nuclear fission reaction may be captured by other uranium nuclei and cause them to fission as well. This can start a nuclear chain reaction (see Figure 11.13). In a chain reaction, one fission reaction leads to others, which lead to others, and so on. A nuclear chain reaction is similar to a pile of wood burning. If you start one piece of wood burning, enough heat is produced by the burning wood to start the rest of the pile burning without any further help from you. You can see another example of a chain reaction at this URL: If a nuclear chain reaction is uncontrolled, it produces a lot of energy all at once. This is what happens in an atomic bomb. If a nuclear chain reaction is controlled, it produces energy more slowly. This is what occurs in a nuclear power plant. The reaction may be controlled by inserting rods of material that do not undergo fission into the core of fissioning material (see Figure 11.14). The radiation from the controlled fission is used to heat water and turn it to steam. The steam is under pressure and causes a turbine to spin. The spinning turbine runs a generator, which produces electricity. In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution, acid rain, and global warming. Fossil fuels are also limited and may eventually run out. Like fossil fuels, radioactive elements are limited. In fact, they are relatively rare, so they could run out sooner rather than later. On the other hand, nuclear fission does not release air pollution or cause the other environmental problems associated with burning fossil fuels. This is the major advantage of using nuclear fission as a source of energy. The main concern over the use of nuclear fission is the risk of radiation. Accidents at nuclear power plants can release harmful radiation that endangers people and other living things. Even without accidents, the used fuel that is left after nuclear fission reactions is still radioactive and very dangerous. It takes thousands of years for it to decay until it no longer releases harmful radiation. Therefore, used fuel must be stored securely to people and other living things. You can learn more about the problem of radioactive waste at this URL: Nuclear fusion is the opposite of nuclear fission. In fusion, two or more small nuclei combine to form a single, larger nucleus. An example is shown in Figure 11.15. In this example, two hydrogen nuclei fuse to form a helium nucleus. A neutron and a great deal of energy are also released. In fact, fusion releases even more energy than fission does. Nuclear fusion of hydrogen to form helium occurs naturally in the sun and other stars. It takes place only at extremely high temperatures. Thats because a great deal of energy is needed to overcome the force of repulsion between positively charged nuclei. The suns energy comes from fusion in its core, where temperatures reach millions of Kelvin (see Figure 11.16). Scientists are searching for ways to create controlled nuclear fusion reactions on Earth. Their goal is develop nuclear fusion power plants, where the energy from fusion of hydrogen nuclei can be converted to electricity. How this might work
