Two women, Arlene and Cheryl, and two men, Burton and David, are all good athletes. One plays tennis, one plays volleyball, one is a swimmer, and one plays golf. One day last week they were seated around a square table, one on each side, arranged as follows:
The person who sat across from Burton was the tennis player.
The person who sat across from David was not the swimmer.
The person who sat on Arlene's left was the volleyball player.
The person who sat on Cheryl's left was not the golfer.
The swimmer and the golfer are husband and wife.
Who is the golfer?
