Please answer this: 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 cannot repair themselves. B The computer has changed a lot. C They have no computers inside. D The computer cannot work if the robot changes Answer: D The computer cannot work if the robot changes Question:

He liked Donna very much. He liked her freckles, and he liked her smile. Felipe didn't want Donna to die. Felipe talked to his mother about Donna. "I am going to die," Felipe told his mother, "and I am going to give my heat to Donna." Felipe's mother didn't pay much attention to Felipe.
