He noticed a haze(霾) hanging over the city and it didn't take long for him to realise that it was the pollution we suffered. At that moment, Chiwewe felt he must do something about it, but didn't know what. He was a computer engineer and knew little about environmental science. He first did research on air pollution and found that it is the world's biggest environmental health risk. He decided to work on it in a cooperative(合作的) way. He talked to scientists, officials, and engineers who helped him develop a deeper understanding of the situation, as well as an idea to improve it. Through years of work, Chiwewe and his coworkers from South Africa and China created an online air quality(质量) decision support system(系统). Based on historical and real-time data(实时数据), the system can correctly predict(预测) air pollution and air quality, which can help people make better decisions about their daily movements, as well as help officials better manage their operations. Chiwewe learned an important lesson — “a lesson we all need to take into heart if we are to work towards a better future. Even if you're not an expert in a certain field, your outside expertise may hold the key to solving problems within that field，” he said. What if Chiwewe hadn't worried to research the problem and do something about it? What if he had just hoped that someone, somewhere, was taking care of the matter? As Chiwewe said，“Why not just go ahead and deal with the problem as well as you can, in your own way? You may be pleasantly surprised.” 根据语篇内容，选择最佳选项。 (　　)1. Where did Tapiwa Chiwewe work?
