5.John has four days to have a graduation(毕业）trip,

However, there are still worries about whether driverless cars are safe for everyone on the road. Even though they use smart technology to avoid dangers and control the car, they’re not perfect yet. In a recent London test, a driver had to take control twice to avoid accidents.
There are a lot of challenges that need to be solved before we see traffic lights disappear. One of these challenges is allowing driverless cars on the roads regularly, which requires solving many safety and technical problems. Driverless cars need sensors (传感器), cameras, and computer systems to operate. However, making these systems work effectively in all weather and road conditions is challenging.
People have mixed feelings about driverless cars. Some people, like Grant Schapps, believe they could be a big deal if we can make them work safely. But some feel uncomfortable with the idea, and most want them to be clearly marked on the road. Experts (专家) think we might need new road signs just for driverless cars because they may have difficulty moving through the roads with heavy traffic or unexpected situations.
In short, while driverless cars offer exciting possibilities, we must deal with many problems before they become common on our roads.
46．What’s the purpose of Paragraph 1
A．To explain an idea. B．To introduce the topic.
C．To advise people to buy driverless cars. D．To tell people how to operate driverless cars.
