text: Linda: Jeff, are you home?
  Jeff: Not at the moment, why?
  Linda: I am not sure if I unplugged the iron.
  Jeff: So, what do you suggest we do?
  Linda: Well, I cannot leave the meeting.
  Jeff: Don't worry. From where I am I'd see smoke if there is a fire at home.
target: Linda isn't sure if she unplugged the iron. She can't leave the meeting to check. Jeff is near the house and he would see the smoke if there was a fire.
