Correct Answer: C
Explanation:
As presented, the initial conditions state the position of the group’s
females relatively clearly. Sarah is stated to be in the seat next to the aisle seat, which eliminates her
from sitting in the end position farthest from the aisle. Kathryn can take the aisle seat; however, if she
doesn’t, then Paul is in the aisle seat and the soonest Kathryn could be seated would be third from the
aisle. Since Kathryn must be sitting by Steve, and James and Mary must be separated by two seats,
however, Kathryn can’t be sitting third from the aisle, as if she was, James and Mary would occupy the
last two seats in the block, violating the conditions. Kathryn and Steve must be sitting so that James is
separated from Mary and sitting next to Sarah, which forces Mary to take the end. Thus, C is correct.
