o  Ex.1:  The child plucked a flower in the garden.

                     a  flower   in   det    n

*  Note that PP is a child of VP indicating that PP denotes a participant
   in the action of plucking (denoted by VP)

o  Ex.2:  The child plucked a flower in the pot
    - Where the above means that flower is in the pot
      (child is not in the pot, and plucking did not
       take place in the pot).
    - Thus 'in the pot' is related to flower directly,
      but not directly to plucking.

                                      the pot            

*  Note  PP is a child of NP in the above.
   - Indicates that PP is directly related to
     (or modifies) NP, and not the VP.
