  4. Who is the spouse of R? We know R's spouse must be either T or Q.

    • Consider if R's spouse is Q: If R is married to Q, then Q (male) is married to R. This would leave T (a man who must be married to one of the group members) with no one to marry, as P and S are unmarried and R is married to Q. This contradicts the statement that T is married to one of the group members.
    • Therefore, R's spouse cannot be Q.

  5. By elimination: Since P and S are unmarried, and R cannot be married to Q (as it leaves T without a spouse), the only remaining person for R to be married to is T.
