Sending a robot into space to gather information is a viable option, but should only be regarded as that—an option. Even the most technologically advanced robots cannot and should not replace manned missions to outer space. Certainly it is cheaper and less dangerous to launch a computer probe that can gather reams of data, but often the information obtained by a machine only serves to produce more questions than it answers. Therefore, the space program should allow manned missions to follow up on those initial information-gathering robotic ventures.
While manned missions are more costly than are unmanned missions, they are also more successful. Robots and astronauts use much of the same equipment in space, but a human is more capable of calibrating those instruments correctly and placing them in appropriate and useful positions. A computer is often neither as sensitive nor as accurate as a human in managing the same terrain or environmental circumstances. Robots are also not as equipped as humans to solve problems as they arise, and robots often collect data that is not helpful or even desired. A human, on the other hand, can make instant decisions about what to explore further and what to ignore.
Select the sentence that offers potential advantages to using robots as information gatherers in space.
选项
答案
"Certainly it is cheaper.. .than it answers."
解析
The best answer is: Certainly it is cheaper and less dangerous to... than it answers. This sentence mentions two potential benefits to robotic exploration of space: lower cost and less danger.
