Question 16 is based on the passage you have just heard.

Passage One

    There’s one sound that gets a big reaction from kids on a hot day, （16）the sound of an ice-cream truck. Maria McCartney has been in the mobile ice-cream business since 2005. “When I was a little girl, I saw an ice-cream truck and knew I wanted to have one someday,” McCartney said. During the hot days of summer, Maria and her daughter drive an ice-cream truck through neighborhoods and parks in Billings. It’s not about making money for this former elementary school teacher. Rather, she wants to（17）preserve the tradition of the neighborhood ice-cream truck. “Truly my favorite part is to see the kids jumping up and down and they just get so excited. It’s great to build a memory for them too. There’s not a lot of these ice-cream trucks around anymore. The parents come out barefoot and screaming, ready to buy ice-cream; they remember when they were kids and they saw a truck,” she said. While the treats may be ice cold, Maria has a warm heart for little faces. Her truck features a donation bucket（18）for kids who don’t have money for ice-cream. “When there are three kids and only two of them have money, I always make sure the third one gets something because I can’t drive away and have that third one not have something,” she said.
