(4) 下線部 it の内容
【元の問題文】
次の英文は、中学生のマイ（Mai）と留学生のトム（Tom）の対話の一部である。また、表はマイが調べた部活動の部員数である。
Tom:Mai, what is this table?
Mai:It shows the number of members in each club at our school. I'm a member of the volunteer club, so I wanted to know about our clubs.
Tom:What 1 in the volunteer club?
Mai:We clean the park near our school every month. We also visit a *nursing home and sing songs with the people there.
Tom:That sounds nice. The soccer team has thirty members. It's very popular.
Mai:Yes. The tennis team has as many members as the soccer team. And the brass band has twice as many members as the art club.
Tom:How about the volunteer club?
Mai:Look. The volunteer club has 3 members of all the clubs. Only eight.
Tom:That's too bad. In my school in Australia, every student had to do volunteer work for twenty hours a year.
Mai:Twenty hours? Did you like it?
Tom:At first, I didn't. But when I helped at a *food bank, an old man said "Thank you" to me with a big smile. After that, I started to enjoy volunteer work.
Mai:I understand. When people at the nursing home smile, I feel happy, too.
Tom:Many students may think volunteer work is hard or boring.
Mai:I think so, too. That's why our club has so few members.
Tom:Why don't you tell other students about your experiences?
Mai:Good idea. I want more students to know that 5.
Tom:I'm sure some of them will join your club.
〔注〕*nursing home＝老人ホーム *food bank＝フードバンク（食べ物を必要な人に配る活動） had＝haveの過去形 said＝sayの過去形
