Identify an explicit feature of each animal in the passage.
A comparison must discuss the same feature for both subjects; two unrelated details are not a useful contrast.
Compare the animals using one shared category and evidence for each.
This is an original practice passage, not a reproduction of a primary source. Read the answer explanations as interpretations of the provided text.
Although alligators and crocodiles look very similar at first glance, they belong to different biological families and possess distinct physical characteristics. Both reptiles are cold-blooded carnivores with armored scales, powerful swimming tails, and webbed feet designed for aquatic hunting. However, their habitats and jaw shapes reveal major differences. Alligators have wide, rounded U-shaped snouts adapted for crushing turtle shells and live predominantly in fresh water marshes throughout the southeastern United States and China. In contrast, crocodiles feature narrower, pointed V-shaped snouts and specialized salt-glands on their tongues that allow them to thrive in salty coastal waters and tropical estuaries across Africa, Australia, and the Americas. Furthermore, when a crocodile closes its jaws, its large fourth lower tooth remains prominently visible on the outside, whereas an alligator's lower teeth are completely hidden.
Which physical trait is shared by BOTH alligators and crocodiles according to the passage?
Answer: B. The text states: 'Both reptiles are cold-blooded carnivores with armored scales, powerful swimming tails, and webbed feet.'
