Of course.It’s dangerous   6   most exciting.”

  The health and physical condition of the people was,   7  , very necessary.Only those in very good health and physical condition were   8  .

  While being trained to be astronauts, they went through many   9  .They studied the star and the moon, and they also studied geology, the science of rocks.This was necessary  10   astronauts would have to look for rocks on the moon.They would try to find rocks which might help to tell the   11   of the moon.They were all   12   to fly in helicopters.There helicopters landed straight down to give them some   13   of the way the spaceship would actually land on the   14  .They were also taught the known facts about the   15   in space.They learnt about all the scientists and engineers who   16   spaceships.They visited the   17   where spaceships were repaired.They learnt how every   18   of a spaceship and its instruments work.They also learnt every detail of ground-control   19  .

  In a word, to be chosen as astronaut, one must be in good   20  , well-informed in science and good at piloting.
