1枚目の本文に対する2枚目の問題の答えを3-イか3-ロで迷っているのですが、どちらが正解かわかりません。どなたか理由もあわせて教えてもらいたいです。 よろしくお願いします!

Omoiyari is said to be a key concept of the Japanese mentality. (Its primary meaning is the ability to imagine other people's feelings. Japanese people's good manners have often (2) been associated with it and reported in news articles. For example, Japanese soccer supporters cleaned up the stadium after the matches at the World Cup, actions that were praised by the foreign media. Some experts say the supporters' behavior is related to education in Japan, where children clean their classrooms every day. Another example was seen during the frequent natural disasters. Even in such situations, many people still kept calm and patiently waited in lines for emergency supplies. JANET [ 3-1 ] According to a survey by an organization to promote good manners in Tokyo, less than 30 percent of Tokyo residents think people in Tokyo have good manners.

Students also take turns (6-c) in charge of cleaning the classroom, serving lunch, taking care of plants and animals. In addition, volunteer clubs collect money for charitable organizations and members visit elderly people in nursing homes. In moral education class, students read stories and discuss the topics in them. The teacher facilitates the discussion and the students draw their own conclusions.
