To find the description for this, it first needs to look up the spot in the map that points to the living-room. The `assoc` command does this and then returns the data describing the living-room. Then the command `second` trims out the second item in that list, which is the description of the living-room (If you look at the `map` variable we had created, the snippet of text describing the `living-room` was the second item in the list that contained all the data about the living room...)
Now let's use our Emacs scratch buffer to test our function. Again, like all the text in this font and color, copy and paste the following text into your Emacs `*scratch*` buffer, move the cursor to the end of it, and type `C-x C-e` to execute it:
      (describe-location 'living-room map)
If you copied all the code into the Emacs `*scratch*` buffer correctly up to this point, you should see the following message:
      ==> (you are in the living-room of a wizards house -
           there is a wizard snoring loudly on the couch -)
Perfect! Just what we wanted! Notice how we put a quote in front of the symbol `living-room`, since this symbol is just a piece of data naming the location (i.e., we want it read in Data mode), but why didn't we put a quote in front of the symbol `map`, since in this case we want the Lisp interpreter to hunt down the data stored in the `map` variable (i.e., we want the compiler to be in Code mode and not just look at the word `map` as a chunk of raw data).
