input question: Write a multi-choice question for the following article: Article: Every year landslides cause 25 to 50 deaths and $2 billion in damage in the United States. And in December, a single _ killed more than 2000 people in the Philippines. Sending workers to stabilize mountainsides using steel bars can help a lot, but it introduces new difficulties because of dust and loosen heavy, dangerous debris from the work. "It's a quite dangerous job," says Giorgio Pezzuto of D' Appolonia, working with eight other companies. Now there may be an answer: a three-ton robot called Roboclimber. "The idea is to operate a machine far away that can do the stabilizing job without a human being near,"says Pezzuto, manager for the project, which is supported by a European organization. Engineers say that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged spider, has cost at least $2 million so far. It should be able to climb mountainsides, drill holes and insert steel bars there. Testing should begin in May.???

"What's ten cents?" they asked themselves. "If it makes this man happy, it won't hurt me very much." In this way David saved a few cents here and a few cents there, and by the end of the year he had saved several hundred dollars. One day he had a very bad toothache and had to go to the dentist.
