　　Does a bee know what is going on in its mind when it navigates its way to 11 food sources and back to the hive, using polarized sunlight and the tiny magnet it carries as a navigational aid? Or is the bee just a machine, unable to do its mathematics and dance its language in any other way? To use Donald Griffin's term, does a bee have "awareness", or to use a 12 I like better, can a bee think and imagine?

　　There is an experiment for this, or at least an 13 , made long ago by Karl Von Frisch and more recently 14 by James Gould at Princeton. Biologists who wish to study such things as bee navigation, language, and behavior in general have to 15 their bees to fly from the hive to one or another special place. To do this, they begin by placing a source of sugar very close to the hive so that the bees (considered by their trainers to be very dumb beasts) can learn what the game is about. Then, at regular intervals, the dish or whatever is moved 16 farther and farther from the hive, increasing about 25 percent at each move. Eventually, the 17 is being moved 100 feet or more at a jump, very far from the hive. Sooner or later, while this process is going on, the biologists 18 the dish of sugar will find the bees are out there waiting for them, 19 where the 20 position had been planned. This is　an uncomfortable observation to make.
