You come across the first trap

You walk across the room to the door. The floor sounds hollow and it rings a alarm bell. you step to the wall and the floor is more solid there. You step following the wall to the door. You feel certain the middle part of the floor may collapse.

• 1 go through the door you have come to
• 2 the middle part falls in
• 3 drop a chair onto the middle of the floor
• 4 wait where you are for twenty minutes then suddenly spring for the door in case a frat boy is going to try to trigger you into a trap
