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).

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.

これの日本語訳を教えてください。

I strongly agree with the idea of making English an official language in Japan. Thanks to the technology, our world is increasingly connected, and being able to speak the international language, English is becoming extremely important. Although Japan has the third largest economy in the world, Japanese people don't have a world- class communicative ability in English. Considering the fact that it is quite common for people in Europe to have an excellent command of English, we are far behind other countries. Making English an official language is a powerful way to encourage people to study hard and to master English. Furthermore, Japan will host Olympic games in 2020 and expect much more foreigners, who cannot communicate in Japanese. We'll have to be able to run the games smoothly and show our hospitality in English. Mastering English is the hurdle we have to overcome sooner or later.
