What can be inferred about the meeting's schedule due to the room's unavailability?

The inference that the meeting has been postponed until next week is correct because the unavailability of the room suggests that the meeting cannot take place as originally scheduled. This leads to the conclusion that the meeting has been rescheduled for a future date, which is specified as next week.

In the context of the other choices, if the meeting had been canceled, there would be no information indicating a future date for it, which is not aligned with the implication of postponement. Similarly, the choice indicating that the meeting is still happening today contradicts the reason for considering the meeting's schedule, as a room's unavailability would typically prevent it from occurring at the current time. Lastly, suggesting that the meeting is now held in a different location does not necessarily follow from the information provided; the room's unavailability indicates a definite disruption rather than a simple change of venue, making this choice less likely.

Thus, postponing the meeting until next week captures the essence of the impact caused by the room issue while still allowing for the meeting to take place later.
