Tanya is older than Eric.
Cliff is older than Tanya.
Eric is older than Cliff.

If the first two statements are true, then the third statement is:

  • A.True
  • B.False
  • C.Uncertain
  • D.Data insufficient

Answer: B

The third statement is False.

From the first two statements: Cliff is older than Tanya, and Tanya is older than Eric. So Cliff is older than Eric, and the order by age is Cliff, Tanya, Eric.

The third statement, 'Eric is older than Cliff', says the opposite, so it must be false. It is not uncertain, and the data are not insufficient, because the first two statements fix the order completely.
