Read the passage and answer the questions that follow.
A company in Sweden has started using driver less electric trucks on a public road.
The project is testing ideas that could bring important changes in transportation. The trucks are called 'T-Pods'. They are shocking to look at because they don't have windows. In fact, they don't even have a place for people to sit inside them. Not even an emergency driver.
What the T-Pod does have is lots of cameras and sensors and a complicated computer system, so that the truck can drive itself. The T-Pod can constantly and quickly exchange information with a control center. Most of the time T-Pods will drive themselves. But when the trucks are in a difficult situation, a real person will be able to take over and drive until the problem is solved.
The small size allows a T-Pod to travel farther and charge faster. T-Pods can go for about 124 miles on a single charge. The developer of the truck says the driver less electric truck costs about 60% less to run than a normal diesel truck with a driver. And it doesn't pollute.
Though the T-Pods can drive at speeds as high as 60 miles per hour, Sweden is only granting the developer a speed limit of 3 miles per hour. That's about as fast as a person walking at normal speed.
The company wants to have 200 trucks on the road by 2020.
What happens to the truck in an emergency?
AA computer programme talks to a person.
BThe truck stops moving.
CThe truck stops moving.
DThe truck has alarms that warn people.
