Read the passage carefully, then choose the best answer for each question.
THE ROBOTS ARE COMING!
The year is 2045. A goal is scored at the soccer World Cup. Not by a human player, but by a robot. A robot? Is that possible? Many scientists believe it is. In fact, there are already robots that can play soccer. Of course, today's robots don't just play sports. Today's scientists are working on robots with various skills. For example, it is very possible that robots will soon help take care of children or the elderly, or do dangerous jobs such as fighting fires.
When people started making robots, they were made to do just simple things, mainly in factories. Since then, however, robots have changed a lot. Early robots were operated by humans. Today's robots function on their own. Some can only move around a little, like robot vacuum cleaners, but others, such as Honda's ASIMO, can do much more. He can run, climb stairs, dance, and yes, even play soccer.
Then there are robots designed to be like humans. These robots have faces and can show emotions. Such robots can learn new things, and show us how they "feel.'' Actroid-DER—a social robot—looks so human, she sometimes makes people feel uncomfortable.
Animal-bots
Scientists aren't just building humanlike robots. They are also making robots that look and act like animals.
At NASA, scientists are making a robot snake. They think it's a good alternative to vehicles with wheels. These snake-bots can enter holes and move over rough ground. They might one day help scientists look for signs of life on Mars. Other animal robots include the frog-bot, which can jump over objects, and the sticky-bot, which can walk up walls. There's even a robot called Water Runner that can walk on water.
But can a robot soccer team ever operate all on their own, or play as well as a human team? Many robot scientists definitely think so. Among the robots of today are Honda's ASIMO (top left), the NASA snake-bot (bottom left), and Actroid-DER—the social robot (right). Anything is possible. One day, they may even be world champions!
The word “they” refers to______.
A.vehicles
B.wheels
C.holes
D.snake-bots
