Select the answer choice that correctly provides the missing premise: _______________________.Stegosauruses were dinosaurs.Stegosauruses were warm-blooded.
  1. All stegosauruses were warm-blooded.
  2. All dinosaurs were warm-blooded.
  3. All dinosaurs were stegosauruses.
  4. All stegosauruses were dinosaurs.
Explanation
Answer: B - All dinosaurs were warm-blooded. Here, the test-taker must recognize that the minor premise and the conclusion rely on a connection between dinosaurs and warm-bloodedness. Since stegosauruses are within the class of dinosaurs, the conclusion can only be reached if “all dinosaurs are warm-blooded.” Answer A is not correct because the minor premise would not be needed to reach the conclusion. Neither Answer C nor Answer D is correct because neither answer establishes warm-bloodedness in dinosaurs.
