Q. 中学英語 長文読解  (2)についてです。  答えはアなのですが、どのような並び替えになるのか教えてください‪🙇🏻‍♀️՞

5 次の英文を読んで、あとの問いに答えなさい。 < 星野改 > High schools in Minnesota have a problem. Many students are late to school. They are often tired. Some students fall asleep in class. They often get sick, too. The local governments take that as a problem. They make a small change. It helps a lot! What do they do? They start the school day a little later. A This small change makes a big difference. Why? Most teens are very tired early in the morning. They usually don't go to bed until after midnight. In the morning, they wake up between 6:00 and 6:30 for school. So they don't get enough sleep. They are still tired early in the morning. But after the change, teens are more awake and (be ready/class/to/in). A later start time is better for a teen's body clock. B Everyone has a body clock. An adult's body clock works like this: most adults get tired between 9:00 and 11:00 at night. They usually go to bed before midnight. Adults can get up early in the morning. It's not a problem. But a teen's body clock is different. Teens don't get tired at midnight. They usually stay up later. But early in the morning, they need more sleep. C The schools in Minnesota pay attention to the teen's body clock. They change the start of the school day from 7:20 a.m. to 8:40 a.m., 80 minutes later. Other schools in the United States change their start times too. Some schools change the time by only 30 minutes, but they still get good results. ( 2 ), the results are amazing! 3 (Many) students are on time. Morning classes are easier to teach. Students are getting ①(good) grades. Students have fewer illnesses, so they are ⑤(little) absent. In Minnesota, there is another important effect: fewer students drop out of school or change schools. D Today, more and more high schools are starting later. Most schools can't start two hours later. But they can change the start time a little. A small change can make a very big difference! Just ask the students. 注 Minnesota ミネソタ (アメリカ合衆国中央北部の州) (1) 次の英文を入れるのに最も適する位置を、本文中のA~Dから1つ選びなさい。 Now the students are happier, and also the parents and teachers too.
