質問です。 (5)のⅡ群のところは答えがクなのですが、私はカだと思ってしまいました、、、 また、(6)については、答えはイなのですが、ウだと思ってしまいました。 どうしてこれらの答えになるのかがよく分からなくて、、 教えて下さい〜!!! 宜しくお願いします。

3 次の英文は, 中学生の花子 (Hanako) が行ったスピーチである。 これを読んで、 問い (1) ~ (9) に答えよ。 (24,5) There are some people cleaning streets in my town every morning. Also, there are some *crows looking for something in the trash. Many kinds of trash are *scattered around the *dump by them. That is a problem of trash and crows. Many people don't want to *fight with crows, but they want to solve the problem. IA J There is one way to solve the problem. I often see yellow plastic bags for trash. I heard that crows 2[(7) put (1) see (5) the yellow / (I) in / () cannot / () the things] bags. If crows think that there isn't any trash in them, they will go to another place, and we don't have to fight with crows. [B] *However, many crows still come to dumps in my town. They learn quickly and understand well, and they know where to find something for their lives. So, they come back to look for it in trash if they think they can do that easily. What are they trying to find in our trash? If I can answer this question, I may find a better way to solve the problem of trash and crows. So, I started learning about crows. My uncle is studying about crows. He often watches crows in some places and tries to understand their lives. He 3 (tell) me about it last week. They get up very early in the morning and usually start looking for their food in the trash of some restaurants or food shops. In such trash, crows can find their favorite food like *French fries or *mayonnaise. My uncle said that they like *oily food. I thought it's interesting because I like the same food. [ C] Also, they want to find something for making their houses. For example, they need *soft things like dog hair or "cotton because they want to put their eggs on such things. I was surprised to learn that crows find these things very well. There are some better ideas to solve the problem of trash and crows, my uncle said. First, people should put a big *net over the trash. When there is a net, it is difficult for crows to scatter trash around a dump. Heavy nets with small mesh are better. Second, when people put their trash in the dump, they should be careful about the time. Usually, the trash is 4(collect) in the morning. Crows may come and scatter it before that if you put the trash in the dump the previous night. 【D If it is difficult for crows to get their food in our town, they will move to another place. 5My uncle knows what we can do to solve the problem of trash and crows because he always tries to understand them. I think he can see the problem from the side of the crows. 6 We don't want to fight with crows, but ? I've heard that the crows sometimes hit people. Do they want to fight with us? That may not be true. My uncle said that the crows are trying different ways to say, "Don't come around our house!" They want to protect their children when someone comes around their house. Crows are large birds and they can fly, so they look strong. However, they are afraid if someone is near them and they don't usually want to fight with us. So, they don't come around the trash when someone is there. I learned about crows and I understood them better than before. They are just trying very hard to get. things for their lives, and they can find them in our trash easily. So, I don't think they are bad. Scattering trash is a problem to us. However, if I see this problem from the side of the crows, then I will know what I can do to solve it. For example, I will not make much food trash, especially oily food trash, and I can be careful about my way of putting the trash in the dump. There is not an easy way to solve the problem of trash and crows, but now, I know it is important to think about it from the side of the crows. We often think about a problem only from our own side, but if we look at it from another side, we may find a better idea.

問2の解説を詳しくお願いします。

次の英文は、裕太(Yuta)が書いたものである。これを読んで、後の各問に答えよ。 "So, let's continue making an introduction about your fathers," said our English teacher, Mrs. Yashima one month ago. This class was Dmind-numbing, and I was thinking of the way to kill the time during the class. 4 I didn't know much about my father He was always busy working, so I didn't have any memories of playing with him at all. He came home late at night, woke up earlier than me, and left for his workplace without having breakfast. On weekends, he was always watching news programs which never interested me. When I looked out of the window, a friend of mine who was living near my home was playing catch with his father, and I projected myself on him. When we were having dinner, he never asked me any nice question. He always said to me, "How are the school and the club going?" I only said, "Not bad," because I thought that he had no interest in my school life or club activity. I didn't know about my father well, but I remember the other face of him. He sometimes repaired things in our home such as the TV set, chair, or bicycle. I wasn't interested in it at all until a neighbor told me a story about my father. She always took care of me when my parents were busy. "Your father is a good person," she said. "He always repairs broken things with a smile. It was just like magic." And she gave me some cookies. I knew about my father a little. The other day, I visited a factory as a part of social study class, and a man spoke to me, "Oh, your last name is..., are you his son? When I was working for another company with him, he took good care of me. He sometimes scolded me, but taught me a lot of things. So, I respect him so much." I knew about my father well. When I told my father about the man, he said to me, "Keep the friendship all the time. If you give a hand to someone, the person will give you a hand back someday. Just remember it." At that time, I understood that my father was a hard worker and he was respected by many people. Though he was a serious and silent person, I felt I knew him for the first time. 2022(R4) LAMANG
