controlled and practically eliminated. We will always need to confront
                  them, however, because human imperfections make them inevitable.
                        There are two ways of ___________mistakes, avoid making them
                  or find them during processing. It is usually better to avoid making

                  mistakes  at  all,  finding  mistakes  in  processing  means  a  repeat
                  measurement must be made and having to repeat work is expensive.
                        If there is no independent check on the position of a point then

                  there  may  well  be  a  mistake  in  one  of  the  measurements  and  the
                  position  will  be  wrong.  ____________that  have  been  made  is  done
                  using  check  measurements.  To  find  the  position  of  a  point  in  three
                  dimensions needs three measurements, any extra measurements can be

                  used  as  a  check  on  the  other  three.  Extra  measurements  are
                  called________.
                        Making extra redundant measurements takes time so a balance is

                  needed between making the check measurements and minimizing on
                  work. The simple rule is that each point should have at least one check
                  measurement for detail work, for positioning the control points at least

                  two should be used.

                        Task  2.  Make  up  a  short  summary  of  the  text  using  the
