    In one question Tc is classified as a naturally occurring element (it is not), and in another question it is the first artificially produced element. How can it be both?

      Tc is the answer to the question “What was the first artificially produced element?”
      Tc also appears in the multiple choice list for the question “Which naturally occuring element was discovered last?” This does not mean that it is a naturally occurring element. Only one of the answers is correct
