Step-by-step explanation:
The best closing for Ravi's presentation to a group of office managers about the office of the future would be to summarize key points and benefits, invite questions and open a discussion, and end with an engaging or inspiring question or quote about the future. A good summary ties together the information presented, reaffirming the audience's understanding of the material. Inviting questions allows for deeper engagement and clarification on points of interest or concern. Concluding with an inspirational thought or a forward-looking question helps to leave a memorable impression, encouraging the audience to reflect on how they can contribute to or prepare for the future.
For instance, Ravi could summarize the main features of the future office setup he presented, answer any queries from the audience to clarify specific aspects, and finally, present a thought-provoking question or quote that ponders the impact of these advancements on the way we work.
