Premise 1: all geckos are lizards.

Question

Premise2: all lizards are reptiles
Which of the following is a valid conclusion for the two premises

Answer 1

Based on the two premises provided, we can draw the following valid conclusion:

Conclusion: All geckos are reptiles.

This conclusion follows logically because:

• Since all geckos are lizards (Premise 1), and,
• All lizards are reptiles (Premise 2),
• It follows that all geckos must also be reptiles.

This is an example of a syllogism, where the conclusion is derived from the two premises.
