28.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.
How can we solve the problem of traffic jams in big cities? Governments have built highways, offered public transportation, etc. However, these traditional approaches are becoming expensive. Many experts now see intelligent transportation systems (ITS) as the solution. But how does ITS work?
Using information technology (IT), intelligent vehicles and infrastructure broadcast and receive data from sensors, video cameras, radar, and satellites, etc. to improve traffic quality. Drivers receive messages on computers or mobile devices about accidents, travel times, alternative routes, and the like. These allow drivers to make better decisions.
Managers of transportation infrastructure (roads, bridges, train stations, traffic signals, etc.) receive ITS data, then use it to control the system by changing traffic signal timing, broadcasting radio announcements, opening and closing roads and traffic lanes, responding to accidents and the like. Computers, rather than humans, make most of the decisions that control the system.
QUESTION: Which of the following can be inferred from the passage?
(20 Points)
A.ITS will offer a cheaper solution to solving traffic problems.
B.Machines will replace human beings in managing traffic system.
C.Highways and public transportation isn’t expensive at all.
D.Governments will switch to ITS instead of using traditional measures.
Đáp án: D
Giải thích: Ở câu "Slang, however, refers to words and expressions understood by a large number of speakers but not accepted as appropriate formal usage by the majority.", tác giả có nhắc đến “Tiếng lóng chỉ từ ngữ và cách diễn đạt nhiều người hiểu nhưng không được phần đông chấp nhận là ngôn ngữ trang trọng.”
