写真の問題より、(3 )に入る言葉の模範解答がbigger,largerだったのですが私はmoreとかきました。moreだとバツにたりますかね?

Tony: What are you going to make a presentation about? Riku I'm going to introduce my idea for a new park. Here is a graph showing "Roles which people want for parks." I think parks serve many important roles. I want to make a wonderful new park in my town in the future. Tony: Great! Riku What is the most important role for parks for you? Tony: Well, I think "A place for eating" is the most important. Riku: I think that is important too. But its percentage is the lowest in this graph. Roles which people want for parks A hub for the community A place for exercise and sports A place for children to play A place for relaxing A place for eating 0% 10% 20% 30% 40% Tony Interesting. In my country, I often enjoy eating lunch in a park. Riku: I think "A place for children to play" is the most important. Many other people also want that role. Tony Yes. Its percentage is a little lower than that of "A place for exercise and sports" and "A hub for the community." But it's higher than the percentage for the other roles. Riku Parks can play a lot of roles in a town. I'll try to make a park that serves important roles. There are many possible roles for a park in a town. I hope people find good roles for my park. Tony: Great! I think your presentation will be really interesting. I want to know more about parks and towns. hub +0 <要約文> Riku is going to introduce his idea. He and Tony look at a graph that shows some (1) which people want for parks. As for the (2) important role for parks, Riku thinks it is "A place for children to play," but Tony thinks it is "A place for eating."
