So i know this is just a joke, but I imagine the simulation limits one's options to those present in the room. If she wants to send someone more likely to survive, like Data, there would be a roadblock:
- Not enough time to get there from the bridge
- Site to site transporter is down
- Spot ate Data's communicator badge
- Data is commanding the saucer section in another sector
- Data is on Risa hooking up with Sela
Something limits the options to those in the room. Georgi is the most qualified, and time is short
