Creating ceramic works of art requires heating them to high temper-

atures.  A test used to distinguish ancient ceramic works from recent

forgeries consists of heating a sample taken from the object and

measuring the amount of radiation given off.  This process allows

one to determine how long ago the object was last heated.

 The information in the passage, if correct, most strongly supports

which of the following?

     A  If an ancient ceramic work of art has recently survived a hot

      fire, the heat test cannot distinguish it from a recent forgery. 

 B     If the heat test shows that a ceramic work of art was not made

      recently, the work is not a forgery. 

    C  Two samples taken from the same ceramic work of art and

      subjected to the heat test at different times will give different

      indications of the time at which the work was made. 

  D    Recent forgeries of ancient ceramic works cannot be distin-

      guished from genuinely ancient works without the use of the

      heat test. 

   E    The temperatures to which samples are heated during the heat

      test are  close to those to which ancient ceramic works of art

      were originally heated.
