问题             Sending a robot into space to gather information is certainly a viable option,
Line  but should be regarded only 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
(5)   that can gather reams of data, but often the information obtained by a machine
      serves only 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
(10)  are also more successful. Robots and astronauts use much of the same equipment
      in space, but a human is much 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
(15)  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.
           While technological advances have allowed us to make incredible strides
      in space exploration, they still cannot match the power of the human brain. This
(20)  "supercomputer" is necessary in order to maintain a space program that can truly
      advance to the next level. [br] The passage supplies information to answer which of the following questions?
选项 A、What is the cost of launching a computer probe into space?
B、What type of information can safely be ignored when exploring outer space?
C、How much information can a computer probe gather in outer space?
D、What is the next level in space exploration?
E、Are unmanned space missions more economical than manned space missions?
答案 E
