Answer whatever you like; if you don't answer at all you'll get the shy option automatically (which also cancels the other options). When you gain control there is very little you can do. Talking to Clayton in the middle of the room is a possibility, or you could watch the musicians. To continue head inside the ladies restroom and go inside the toilet in the back.
As Aiden, explore the main hall and look for a [BLUE ORB] in the area straight across the large stairs; as you move away from those stairs going straight ahead, it's in the right corner.
There are two rewarding ways to do this mission (a third option is also possible which requires you to take hold of a guard, but this does not grant any trophies so it's not advisable).
The first option is to head up (as Aiden) and go inside the room with the slightly opened door and fiddle with the monitors. Knock over the guard's coffee or buzz his TV to take another shot at pausing the monitor, then go through the double doors and approach the desk. Hit the switch in one of the drawers and open the safe, then read the book. If you do all this with only Aiden, you'll receive the 'Clean Job' trophy at the end of this chapter.
The second option is to take control of the Sheik in the main area. Walk him to his office and unlock the safe, then read the book. This grants you the 'Possesive Spy' trophy.
The third option is to take control of the guard upstairs (with the orange aura) and head through the double doors (you can try opening other doors but you can't enter those rooms with the guard). Approach the desk and hit the switch, then attempt to open the safe, which doesn't work, so exit the room with the guard and move out of him. Alternatively you can just find the switch with Aiden. Read the book and note down its contents by holding the correct buttons, then get up afterwards by tapping X. You can clean up Jodie's face at the sink, although it isn't necessary in order to continue.
