Explanation Skill

They are ready-at-hand five tips from what I'm studying through this book.

1. Speaker's Request and Listener's Benefit

   +--------------------+
   |Intention of Speaker|
   +--------------------+
             V
   +--------------------+  +-------------------+
   | Action to Request  |<-| Scientific Ground |
   +--------------------+  +-------------------+
             V
   +--------------------+
   | Benefit/Disbenefit |
   +--------------------+

   Listener is motivated by benefit/disbenefit, not by scientific ground.
