What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. But, most important, constant loud noise can cause a loss of hearing. Scientists use a unit of measure called decibel to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands can measure over 120 decibels. Noise at this high level causes the great hearing loss.

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: French doctors and American scientists have reported doing an operation in which the doctor was outside the operating room. This kind of operation is known as robotic operation. Doctor Marescaux did the operation in an office in New York City last month, while a sixty-eight-year-old woman patient was in a hospital in Strasbourg, France. A doctor in Strasbourg got the patient ready. He placed medical tools and a small video camera in her stomach area. Doctor Marescaux in New York watched the patient on a video screen. Then he used the computer to send messages to the robot machine. The robot moved the tools that cut the woman's gallbladder away. The woman got well soon after the operation and left the hospital two days later. Experts say the main problem with such a robotic operation is based on high-speed telecommunications between the doctor and the robot. Technology must be able to send a doctor's order to a robot to move the tools quickly. Experts also say a successful robotic operation will improve an operation. For example, the robot can make much smaller movements than a person can. A robot machine can turn tools in ways that a doctor's hand cannot. Doctors say such a robotic operation will make possible safer and better operations in the future. They say it will improve doctor training. It will also mean that doctors could do an operation on people in dangerous places far away. And it could mean that people could have operations done by top doctors without having to travel to the city where doctors work. Options: A a special kind of robot invented by doctors B an operation done far away C an operation done with the help of a robot D something done to mend a robot Answer: C an operation done with the help of a robot Question:???
