Task: Question Answering
Input (English): Background Paragraph: One reason radiation is dangerous is that it can’t be detected with the senses. You normally can’t see it, smell it, hear it, or feel it. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one in Figure below , has a tube that contains atoms of a gas. If radiation enters the tube, it turns gas atoms to ions that carry electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. 
Story: Tom and Jacob are carrying Geiger counters through an old abandoned city near a nuclear plant. Tom walks into a hotel and looks around at all the paintings and old couches in the lobby. His Geiger counter remains silent, but as he walks up the stairs toward the second floor it starts to slowly but steadily make more sound. Jacob steps into a grocery store when his Geiger counter immediately starts making lots of noise, but his device starts to drop off in sound as he walks toward the freezer in the back of the store. 
Question: Who is currently detecting more radiation?
Output (English): Jacob.
