Fact 1: Robert has four vehicles.<br>Fact 2: Two of the vehicles are red.<br>Fact 3: One of the vehicles is a minivan.<br><br>If the first three statements are facts, which of the following statements must also be a fact?<br>I: Robert has a red minivan.<br>II: Robert has three cars.<br>III: Robert's favorite color is red.

Correct Answer: None of the statements is a known fact.
There is not enough information to support any of the statements. Robert is known to have a minvan, but it is not known which of his vehicles is red. Robert may have a pickup or sport utility vehicle, so the second statement cannot be supported. There is no way to know if Robert's favorite color is red (statement III).
