SAT OwlQuestion bank / Text Structure and Purpose
The axolotl, a salamander native to lakes near Mexico City, can regrow lost body parts, including legs, parts of its heart, and even portions of its brain. Scientists study axolotls in hopes of learning how this regeneration works. Someday, their research might help doctors find new ways to heal injuries in humans.
Which choice best states the main purpose of the text?
To describe an animal's unusual ability and explain why scientists study it
To argue that axolotls should be kept as pets
To compare axolotls with other species of salamanders
To explain how doctors currently treat injuries in humans
Show answer and explanation
Answer: A
The text describes the axolotl's ability to regrow body parts and then says scientists study it hoping to help human medicine. Choice A covers both parts.
Choice D is tempting because the text mentions doctors, but it only suggests possible future treatments and says nothing about current ones.
