Here are the terms matched to their descriptions:
- Registrar - knows where all the pieces are and keeps detailed records of where paintings can be found.
- Preparer - makes sure that all art is installed in the gallery the best way.
- Curator - decides on pieces needed for the museum and acquires them.
- Docent - typically provides educational tours and information to visitors (not listed in your descriptions, but this is the general role of a docent).
- Director - overall leader of the museum, often involved in decision making (not listed in your descriptions, but this is the general role of a director).
If your list only consists of the first three terms and descriptions, just the first three matches will suffice.
