and therefore lives shorter. An animal's ability to maintain homeostasis not only depends on the amount of energy it allocates to maintenance but also on the quality of the *tissue it produces. And the quality of that tissue is at least partially due to the energy it invests in making biomass. In other words, fancy stuff costs more to make but lasts longer.

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.
