Six Natives (Posted on 2013-01-14) Difficulty: 1 of 5
In a remote island there are only two types of people live on the island, Knights and Liars. Knights always tell the truth. Liars always speak falsely.

A group of six inhabitants, comprising Abe, Ben, Cal, Dan, Eric and Frank, was busy in a discussion. A visitor from a nearby city approached them and asked them what type each of them belonged to. Their reply were as follows:
   Abe: None of us is a knight.
   Ben: At least three of us are knights.
   Cal: At most three of us are knights.
   Dan: Exactly five of us are knights.
   Eric: Exactly two of us are knights.
   Frank: Exactly one of us is a knight.
Determine the type of each of the six inhabitants from the aforementioned statements.
