     Consider the sentence "John gave Mary a flower", with the
     following pregroup diagram:
 
-    ```
-    John       gave      Mary    a    flower

     The tree for this diagram becomes:
 
-    ```
-    gave_1 (s)
-      ├ John_0 (n)
-      ├ Mary_2 (n)
-      └ a_3 (n)

+        └ a_3 (n)
+            └ flower_4 (n)
 
     where the numbers after the underscore indicate the order of each
     word in the sentence. This representation is sufficient for
