1 次の英文は, ある新聞の投稿欄に掲載されたものである。 英文を読んで, あとの問いに答 えなさい。 (福 井) We have a lot of problems around us. When the problems are too big, we think we can't solve them. But if we look at the problems from a different view, we can sometimes find the answers. I will tell you about Mexico City. It is not as large as Tokyo, but it has more people than Tokyo. It is ina high place and it has only one big river. So it is difficult to get enough water. About 160 years ago, many people began to use water under the ground. Do you know what happened after a lot of people used too much water under the ground? Yes. The ground went down very much. That was a big problem. Then people in Mexico City looked at this problem from a different view. Some people thought, “How about using the place that went down?”、Other people thought, “Can we use the water we have already used again?” They put the water into the place. Soon it became a kind of lake. People made the water clean and used it again. We have an example in Japan, too. In big cities it is especially hot in summer. There are many reasons, and we know one of them. There are not so many trees in the big cities., If there are many trees, they can give us some shade in many places and the températúre around us will go down. But the big cities have few places for trees because they have a lot of huildinos Some penle thouoht about the problem hard TThen thev 1aorod ota building

Earth has two sets of poles: the geographic poles and the magnetic poles. The geographic poles are located at the northemmost and southernmost ends of the earth. The location of the magnetic poles, on the other hand, are ( ア ) moving, This fact has several implications for navigation and transportation. Shifts in the position of the North Magnetic Pole are nothing new. Since 1831, scientists have been tracking its location. The movements are caused by changes in the flow of swirling molten iron in the earth's core which affect how the earth's magnetic field behaves. What is surprising to scientists is the speed at which the pole has been moving in recent years. For most of the 20th century, magnetic north was located around the northern parts of Canada. It drifted around, moving slowly north at an ( イ ) speed of approximately 10 kilometers per year. In recent decades, that rate has increased significantly to about 55 kilometers per year. The North Magnetic Pole is now moving away from Canada toward eastem Russia. While scientists can't fully explain how changes in the carth's molten core are affecting the pole's movement, they can map the earth's magnetic field. Doing so allows them to ( ウ) hé rate of change over time. This, in turn, provides information on how the magnetic field may shift in the future. Information on changes to the earth's magnetic field is used to produce the World Magnetic Model (WMM). This model is used as the basis for all fornms of modern navigation, from how ships move at sea to mapping software in smartphones. ( エ) in the model, caused by shifts in the real location of the North Magnetic Pole, can seriously impact almost all foms of modern transportation. The model is updated every five years, but in 2018, during routine checks of the 2015- 2020 model cycle, scientists noticed a problem. Because of the rapidly shifting pole, the WMM was close to being outside the acceptable limits for navigational errors. This forced the release of an updated version of the model、 It was revised ( オ ) in 2020, and the current version is expected to last until 2024, As well as keeping track of the WMM's accuracy, scientists continue investigating why the magnetic field is changing so dramatically. This essential work will ensure a safe journey for everyone navigating their way through the world.
