QuestionAとBの1について、私の回答で丸はもらえますか？教えていただきたいです 北大2017年の英作文の問題です。

Read the following passage. for my age. I leave home early and it takes about two hours on a crowded train to get to the office. I get Sunday off, but on the other days I'm usually in my office till nine o'clock, or even midnight on occasion. But I enjoy seeing the customers excited about our new products and services. Every August I take a 15 years. It's a secure job in a major company and I enjoy a relatively high salary six-day summer vacation, usually at my parents' place in Toyama. It's nice to Thave been working for a Japanese cell phone company in Tokyo for the last 2017年度(3] 32 a or the space of the countryside after my cramped apartment in the suburbs. However, I spend two days travelling there and back, and then it's straight back to work the next day. Last summer, however, I was able to take 10 days off in August and used the rare chance to take my wife on a foreign holiday by going to visit my old friend, Pierre, in Paris. He and I met at university in the US nearly 20 years ago when we were both international exchange students. We shared a love of tennis and S0on became good friends, and have stayed in touch. He now works as a supervisor in a post office in eastern Paris. It was lovely to see Pierre again and spend time in the spacious apartment he shares with his wife. I was very surprised to find that they were just back from a month-long summer vacation in southern France and Switzerland. Pierre told us that this is perfectly normal in his job, and couldn't believe his ears when I mentioned that my usual vacation is around a week and that I work 12 hours a day, six days a week. His usual workday, he said, was from 9:00 to 16:00. He wasn't joking ; he was back home by bicycle by 16:20 every day. He likes his job as the postal service fulfills a vital function in society by connecting people both aomestically andinternationally. On hearing his story, though, I began to reflect upon my own life and work. AmI working to live, or just living to work ? Answer questions A to C in English. You may use words and ideas from the Lext, but you must not copy complete sentences.

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
