While researching a topic, a student wrote the following notes: (1) A donor funded wireless headsets for the theater's stage crew. (2) Before the headsets, crew members relied on hand signals from opposite sides of the stage. (3) The headsets allow the stage manager to coordinate scene changes quietly. (4) The theater wants donors to understand backstage impact, not only audience-facing results. (5) The update should be specific and appreciative. (6) The production includes several quick scene changes. The student wants to write the donor update. Which choice most effectively synthesizes the notes for this purpose and audience?
