问题 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.
According to the passage, all of the following are advantages of humans over robots EXCEPT
选项 A、humans can more accurately manage the data collected
B、humans can apply critical thinking skills to new situations
C、humans can only calibrate instruments designed by robots
D、humans are more sensitive to environmental changes
E、humans are better at preparing instrumentation for use in space
答案C
解析 The best answer is C. Humans may be better at calibrating instruments, but the passage makes no mention of who or what might design those instruments.
