Four friends—Ben, Cara, Anna, and Dan—sit in a row of four chairs numbered 1 to 4 from left to right. Ben occupies an end seat. Dan sits immediately to Anna's right. Cara sits somewhere to Dan's left. Anna cannot sit adjacent to Ben. What is the left-to-right sequence of friends?
Ben, Cara, Anna, Dan.
Dan sits immediately to Anna's right, forming a pair (Anna, Dan). If Ben were in seat 4, Anna and Dan would occupy seats 1 and 2, placing Cara in seat 3 (to Dan's right, which breaks the rules). Thus, Ben is in seat 1. To keep Anna away from Ben, Anna and Dan must take seats 3 and 4, leaving seat 2 for Cara.
