根据以下材料，回答题The annual contest aims to direct young people toward careers in science and technology. It is spon-sored by a consortium of professional and technical societies and some major U.S. corporations. The students built tabletop scale models of their designs using recycled materials, costing no more than$100. The teams also had to write essays about their solutions, explain their ideas to the crowd~and answer the questions asked by a six-member expert panel.
GregoryBentley, CEO of Bentley Systems Incorporated, one of the competition's majors sponsors, said this year's theme was”urban transportation”--an increasingly important issue for the world's cities. The Fu-ture City competition, now in its 22nd year, is deliberately focused on young teens. Bentley says, ”Because at that age in the United States, they have to elect the math courses, the advanced math courses. If they don't at that age, they will never be an engineer.”
Some of this year's participants predicted the public transport would be effortless and eco-friendly. For example, David imagines a new system that focuses on magnetic frequency which will allow people to float along the fields. And Mezza imaginesa city relying on electric cars. Whenever cars are parked over here,they get their energy to drop on.
The grand prize of this year's future city competition is $7,500. The team members won a trip to U.S.Space Camp. Even if they didn't win, the experience of working on an engineering project has encouraged many of the kids to think about a career in science and technology. One of them is Eric from New Mexico, ”I plan to become a scientist of some kind, but I'm not sure exactly what kind.”Eric does not have to worry. He has plenty of time to decide.

B．high school students
C．university students
