A chemist would be asked to either A. determine the materials used to make the pots; or C. recommend how to store the pots to prevent further damage. Seeing as a chemist would be needed to find the chemical makeup of the pots, and then to ensure that there will be no negative reactions with chemicals in the air or chemicals the pot may come into contact with.
Work Step by Step
A. and B. were the logical answers as they each have to do with the materiel that the pots were made of and whether or not they would react negatively with certain environments, chemicals, or elements. C. was obviously not an option as a chemist would not be asked to explain designs.
