Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: The United States is one of the greatest fruit-growing countries in the world. Fine red apples come from Washington and New York. Golden oranges come from Southern California and Florida. Fruit grows in all parts of America. The kind of fruit that is grown depends on the weather in each place. Orange trees cannot be grown where temperatures drop below freezing. Southern California and Florida are far from each other, but their weather is much the same. They do not often have freezing temperatures. In Washington, apple trees are planted near the Atlantic Ocean. In New York, they grow near the Great Lakes. Apple trees are often planted near water. Water temperature changes more slowly than land temperature. Near water, temperature does not drop so fast. There is less chance of frost in late spring or early autumn. Frost can kill apples. America has many kinds of weather. It has many kinds of soil. Because of this, they grow and eat more fruit than any other country in the world. Options: A orange trees usually grow where it is cold B different fruits grow in different weather C the cold cannot kill oranges and apples D apple trees cannot live through cold winter Answer: B different fruits grow in different weather Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: In some science fiction movies, evil robots refuse to die, no matter how hard people fight back. Now science fiction has become science fact. For the first time, scientists have made a robot that can take a beating and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs. Until now, even the most advanced robot was almost certain to break down when it was damaged . That is because its computer inside simply doesn't know how to make the machine work after its shape has changed. To deal with this problem, the scientists put eight motors and two sensors that read how the machine is working. They all give signals to the machine's software. Using this information, the computer can then figure out the machine's shape at any moment. The new technology is a big advance in robot-making, scientists say, and it's far from scary. It may someday help scientists create better artificial arms and legs and give new freedom to people who lose _ . It might also help scientists understand how people and animals figure out their own sense of place in space. "It has been difficult to design robots that can work well when the environment changes or when it's damaged," says Olaf Sporns of Indiana University in US. "With this work, we are nearer to solving this problem." Options: A They can replace the computer when it's broken. B They can find out where the damage comes from. C They help the computer learn the robot's condition. D They can send signals to the person who uses the robot. Answer: C They help the computer learn the robot's condition. Question:

The answer is:
How do the sensors in the robot work?
