1. Analyze the cladogram: In a cladogram, organisms that share more recent common - ancestors are more closely related. Turtles, snakes, lizards, and crocodiles share a more recent common ancestor compared to their relationship with other groups shown in the cladogram.

• Amphibians do not have a skull with two openings according to the cladogram.
• Sharks do not possess a swim - bladder as indicated.
• Lampreys do not have lungs.
• Snakes are more closely related to turtles than to crocodiles based on the cladogram.
• Reptiles (turtles, snakes, lizards, and crocodiles) share a common ancestor and are more closely related to each other than to other animals in the cladogram.

Answer:

Reptiles (turtles, snakes, lizards, and crocodiles) are more closely related to each other than they are to any other animals.
