I remember answering this one incorrectly and when the answer was explained to me I was annoyed with myself. Here is your chance, with the original word phrasing:
Jack is looking at Anne, but Anne is looking at George. Jack is married, but George is not. Is a married person looking at an unmarried person?
A) Yes
B) No
C) Cannot be determined
The first with the correct alternative with the correct logical explanation ... (you know the drill).
