In 2015, another survey asked 15-year-old students in 48 countries and regions about their life satisfaction. They answered on a scale of 0 (not satisfied at all) to 10 (completely satisfied). Look at the table. In Japan's score was 6.80. This was well below the average of 7.37. Japan ranked sixth to last. Other Asian students also showed low levels of life satisfaction. Asia, there are many places where society emphasizes academic results. This social pressure may explain the lower satisfaction of Asian students. In contrast, the scores were generally high in Northern Europe, including Finland. These countries ar known for their advanced welfare systems.

次の英文 [A][B] [C] の内容に関して (27) から (38) までの質問に対して最も 3 適切なもの、または文を完成させるのに最適切なものを1.2.3.4の中から~ C [A] From: Noel Lander <noel@coffeeshopsupplies.com> <thedaydreamcoffeeshop@goodmail.com> To: Gary Stein Date: June 5 Subject: Your order Dear Mr. Stein, Thank you for placing an order by telephone with Jenna Marks of our sales department this morning. The order was for 500 medium-sized black paper cups with your café's name and logo printed on them. According to Jenna's notes on the order, you need these cups to be delivered to you by Saturday. I am sorry to say that we do not have any medium-sized black coffee cups at this time. What is more, the machine that makes our coffee cups is currently not working. The part that is broken was sent for repair the other day, but it will not be returned to our factory until Friday. Because of this, I am writing to you to suggest some alternatives. If you really need black cups, then we have them in small and large sizes. However, I guess that size is more important than color for you. We have medium-sized coffee cups in white, and we could print your logo on these instead. We also have medium-sized cups in brown. We are really sorry about this problem. Please let us know which of these options is best, and we'll send you an additional 50 cups for free. Our delivery company says we will need to send the order by Wednesday so that it arrives by Saturday. Please let me know your decision as soon as you can. Sincerely, Noel Lander Customer Support Coffee Shop Supplies

Today's theme is the development of Information Technology in schools. Information Technology has been developing at our school (A) the past three years. When we entered this school, we get our own tablets. Since then, we have used them in our classes or at home. For example, we can collect some information or material for speeches in English classes. So, it has become easier to tell our opinions to our classmates or teachers. But now, I have a question and I want your opinions. B C
