Timothy notes that his five best friends do not know one another. To get things started he invites three of them to lunch: Adams, Brown, and Carter. (The two other friends are Dickinson and Emerson.) The first five names are, in no particular order, Alex, Bob, Chip, Dave, and Elmer. After the luncheon, Timothy lists the results:
* Bob still does not know Brown.
* Chip knows Adams.
* Dave knows only one of the others.
* Elmer knows three of the others.
* Alex knows two of the others.
* Dickinson knows only one of the others.
* Emerson knows three of the others.
What is the full name of each of the five?
