     Surface Exploration. Robots make great explorers on planets,moons,and other landing areas.
Aside from Earth,just about every surface in the solar system is unsafe for humans to explore.The
air on most other planets is insufficient for humans to breathe,making it necessary to wear a space
suit and oxygen equipment.The temperatures on these surfaces are much too hot or much too cold
for any humans to withstand.Plus there would be complications with radiation,weather,and a lack
of gravity.Robots have much less limitation in these areas and can survive much longer under these
conditions.
     Data Collection. Robots are designed for collecting scientific data.Robots are also able to
perform many tasks at one time and can process information much quicker and more efficiently.
Important scientific projects from detecting minerals,analyzing ground samples,and finding water
are all performed much quicker and more accurately(精确地)by robots.
     Cost Effective. The use of robots has made the cost of space exploration much less expensive
than it would cost for humans to do the work.In order to successfully send humans into space we
would need to build a vehicle that can not only carry humans,but also have enough food and water to
keep them alive for the duration of the trip.Moreover,robots have no problems working for hours on
end.Robots never complain,they don't require food or water,and they never need a bathroom break.
     Space Travel. Over the past 30 years or so there have been many different types of robots used
successfully in the exploration of space.Perhaps the most famous and successful robots are the Spirit
and Opportunity who have both been exploring the surface of Mars.They have both been very
successful with experiments on soil and rocks and have even found evidence of water in Mars' history.

D．Many different types of robots have explored the space successfully.

2．Which column of the passage could come from?
