For example, if someone asks you "What time is our meeting with the client?" and you answer "I think it is at 4PM" you are indicating that you do not know or are not sure of the meeting time. Therefore, if you do know the time of the meeting, it is best to answer "The meeting is scheduled for 4PM."
