Six persons Joe, Hazel, Jordan, Thomas, David, and Cristian sit in a linear row from west to east, but not necessarily in the same order.
Some persons are facing the north while some persons are facing the south direction.
Two persons sit between David and Joe, who sits second to the left of Hazel.
Thomas and Jordan sit immediate right of each other. Neither Thomas nor Jordan is a neighbour of David. Thus, case 1 and case 2a are invalid.
Cristian and Jordan sit second to the left of each other.
If Hazel faces in the north direction, then referring to case 1a:
Joe sits immediate to the right of Cristian.
