Repeated Division w/Remainders
N is a positive integer.
When N is divided by 3, the quotient is Q1 with remainder 1.
When Q1 is divided by 4, the quotient is Q2 with remainder 1.
When Q2 is divided by 5, the quotient is Q3 with remainder 1.
If Q1, Q2, and Q3 are positive integers, find the smallest possible value for N that will make all of this work.

Barbara: Eleanor was not first.
Chris: I was not last.
Don: Chris was lower than Barbara.
Eleanor: Barbara was second.
The comments of those who took first and second place are false; those of the others are true. Who won what prize?
