長文です。答えはイ何ですが、その根拠となるところがわかりません。

(*印の付いている単語·語句には, 本文のあとに [注] がある。) There are many museums and *theme parks around Tokyo. Some of them teach people about the history of Japan, like *Edo Wonderland in Nikko and the "Edo-Tokyo Museum in Ryogoku. They are popular places for school trips because students can enjoy learning about Japanese history. I remember one of my school trips. When I was a student in Australia, we went on a school trip to Old Sydney Town. It was a theme park that *recreated the *past, just nke Edo Wonderland in Nikko. Old Svdnev Town was an hour away from Sydney Dy bus. 1t had more than 30 buildings. They were made in the same 'style as buildings in 1803. Many *actors were working at the theme park. They *wore old-style clothes, spoke old-style English, and "pretended to live in the town. “Horse-drawn wagons went up and down the streets. upin My friends and I were excited to see the actors' "performances. People drank at a "pub, sang old songs and danced in the streets. Some of them pretended to “fight a duel Some museum “staff gave us short history lessons, and we enjoyed listening to them very much. I remember Old Sydney Town was very exciting, because it brought us to another world. Old Sydney Town closed about 30 years after it opened. Many people visited there at first, but the number of people visiting there "gradually went down. The buildings started to become old. and more and more actors left Old Sydney Town. There were a lot of people who enjoyed visiting Old Sydney Town when they were children. And later, they took their own children there, but they said it was not as exciting as before. Why did Old Sydney Town close? There are many different "opinions about it. Some people say young people now like to play video games, and these young people think that a trip through time is not very exciting. Other people believe that Old Sydney Town did not *attract many people because it could not make new and exciting *entertainment. Times change and people also change. New "technology and the Internet can make new kinds of entertainment, and people can enjoy them at home. New building *materials can now make buildings that look like something from the future. New technology will make us more surprised. But it is also very important for us to keep old culture and entertainment. Maybe some of these things are not seen in everyday life, but they make a "link with the past. For example, if you go to see kabuki, maybe you will think about Japanese people who lived in the past. Culture *is made up of all the things people did in the past, and it makesa country and its people "unique. If we forget about the past, then we lose our culture. 10

I had a neighborSayama-san,jand he was always yelling at me and my friends to stay away from his house and his old truck. He looked very strange for me. day I was in a coffee shop near my school and talked with a friend about my hometown. Suddenly a student next to us talked to me and said, "Are you from Koishidani? Do you know Ten years latet, I became a college student, and started to live in Tokyo. One an old man named Sayama there? He drove an old blue truck." “Yes," I answered. “He's my neighbor. Do you know him?" “I do! OWhat a nice coincidence!" said the student and he told me that three years ago, he, his mother, and his little sister spentadayin the mountains near my hometown. “While my sister and I were playing around the river in the mountains, I cut my left hand. It was very bad and Mom told us we had to find a doctor." But @the bus back to the town didn't come for another four hours. The three decided to walk bac to the town. However, it was very far. “My mother kept telling me to be all right, but I knew that she was really worried." “Just then, a small blue truck came up the road in front of us. Mom stopped the truck, and its driver was Sayama-san. She told 3what happened, and asked him to take us into town to see a doctor." “He told us to get in his truck, and that there was some ice for my hand in a box." The student told me that he could not remember much about the trip to the doctor. However, when he finally walked out of the doctor's room, Sayama-san was sitting with his mother and sister to take them back to Koishidani. So, they could catch the last train home. On the way back,Sayama-san told us that he had a neighbor named Aki around my age. OSo you are Aki, right? When you see Sayama-san again, tell him that my left hand is fine now, andIm studying piano." “Tll ©do that," I answered. Our school is large, and I never met the student again. ButI saw Sayama-san again. ©I see him with new eyes now, and I am glad I have a neighbor like him. 1 下線部のが表す内容として最も適当なものを, 次のア~エから一つ選び, 記号で答えなさい。 ア なんて美しい景色なんだろう! ィ なんてきれいな貨幣なんだろう! ウ なんてすてきな偶然なんだろう! エ なんてひどい事故なんだろう! 2 下線部のについて, 4時間もバスが来ないことが分かると, 三人はどのような行動をとろうとした
