Five people are standing in a line to buy ice cream. Alice is neither first nor last. Bob is standing somewhere behind Charlie. David is standing directly behind Alice. Emily is standing first in line. What is the exact order of the line from front to back?
Emily, Charlie, Alice, David, Bob
Emily is 1st. Alice cannot be 1st or 5th, and David is directly behind her, making them a block (Alice, David). For Bob to be behind Charlie, Charlie must be 2nd, placing the (Alice, David) block at positions 3 and 4, which leaves Bob at 5th.
