A new library has been built and everything is ready to open the doors. You chair the opening day committee and you are now asking the members the needed questions to make sure all will go well.
You need to find out if:
the main speaker has been selected and if the person has been invited
the master of ceremonies is ready
the major has been invited to say a few words
the authors have been invited for the book signing
the comedian is ready for her performance
the Boy Scouts are ready to set out the chairs and tables and direct traffic.
