Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 31 to 35.
RoboCup is a football competition that has taken place every year since 1997. But the players are not human; they are robots. The aim is to create, by the middle of the 21st century, a team of robot footballers that are able to play against and beat the winners of the real World Cup.
In order for robots to play football, robotics companies have had to develop special technologies. Each robot is fitted with a webcam which is connected to a computer inside the robot. The robot is able to see where the other players are, where the goal is and, most importantly, where the ball is.
They are programmed to make their own decisions and during the match the robots' creators are not allowed to tell them what to do. The robots are, however, able to communicate with other members of their team, via a wireless network.
The technologies that are being developed for scoring goals have other uses as well. It may be possible to develop robots that can be used in search and rescue, for example, finding people trapped in buildings after earthquakes. They may not be as fun to watch as real footballers, but at least they don't demand enormous salaries!
