In an office building resides a company with three employees: Navin, Elif, and Jia. Navin works in marketing, Elif is in the finance department, and Jia is the office manager. The company's policy requires employees to lock their offices when they are not present.

One Monday morning, the CEO informs everyone during a meeting that there will be a surprise inspection sometime during the week to ensure that all employees are following safety protocols, including locking their offices. The exact day of the inspection, however, is kept confidential and only the CEO knows when it will occur. On Monday after the meeting, Navin tells Jia that he won't be in the office on Wednesday due to client meetings.

On Tuesday, Navin and Elif happen to leave the office at the same time for lunch. Navin mentions to Elif that he is worried about the inspection since he will be away the next day. Unbeknownst to them, the CEO who had left the office earlier had informed Jia that the inspection would be on Thursday. Jia noted this but has not yet had a reason to share this information with anyone.

On Wednesday, Navin is out of the office as mentioned. Jia and Elif are working in their respective locked offices. Late in the evening, while still at work, Jia tells Elif that she is glad they don't have to worry about the inspection until tomorrow. Elif then realizes she has an errand to run first thing on Thursday morning and might not be in the office when the inspection occurs.

Given this information, consider the following:

1. What does Navin know and not know regarding the inspection?
2. What does Elif know and not know regarding the inspection?
3. What does Jia know about what Navin and Elif know and don't know?
4. Suppose on Thursday morning, the CEO decides to postpone the inspection to Friday without informing any of the employees. If no further conversations take place, what incorrect assumptions might each employee hold about the inspection?
Navin knows that the inspection will occur sometime during the week, but he does not know the specific day the inspection is scheduled to happen. He only disclosed to Jia and Elif that he would be absent on Wednesday. Since he was out of the office on Wednesday and did not interact with the CEO or Jia, he would not be privy to the information shared by the CEO to Jia about the inspection being on Thursday.

Elif is aware from her conversation on Tuesday with Navin that he would not be present in the office on Wednesday and is worried about the surprise inspection. On Wednesday, Elif learns from Jia that the inspection is scheduled for Thursday. However, Elif is unaware that the CEO has postponed the inspection to Friday since she has not been informed of any changes to the plan.

Jia knows that the inspection is set for Thursday, as she was informed directly by the CEO. She knows that Navin is unaware of the exact day of the inspection because she hasn't had the chance to share this information with him, and he was out on Wednesday. Jia is also aware that Elif knows the inspection is meant to be on Thursday because she personally informed Elif of this on Wednesday evening.

If the CEO decides to postpone the inspection to Friday without informing any of the employees, each of them will hold onto their last known information about the inspection. Navin would still be under the impression that the inspection could happen at any time during the week, since he has not received any new information and is unaware of the initially scheduled Thursday inspection or the subsequent postponement to Friday. Elif, having been told that the inspection is on Thursday, would assume that she might miss it due to her errand in the morning unless she is directly informed of the postponement. Jia would be expecting the inspection to occur on Thursday, since she was the one who had received this information from the CEO initially and there has been no new communication to change this understanding. All three employees would thus be operating under incorrect assumptions about the timing of the inspection due to the lack of updated information following the CEO's decision to reschedule.
