What is the author's primary purpose in writing this essay?
- A. To explain how the markings on a snake are related to its venomous nature.
- B. To teach readers the difference between coral snakes and kingsnakes.
- C. To illustrate why snakes are dangerous.
- D. To demonstrate how animals adapt to difficult environments.
Correct Answer: B
Rationale: The correct answer is B. The author's primary purpose in writing this essay is to teach readers the difference between coral snakes and kingsnakes. The essay discusses how skin coloration and markings help snakes hide from predators and indicate whether a snake is venomous. By comparing the physical characteristics and behaviors of coral snakes and kingsnakes, the author helps readers understand how to distinguish between the two species to avoid potential dangers. Choice A is incorrect because the essay focuses more on distinguishing between snake species rather than solely on the relationship between markings and venom. Choice C is incorrect as the essay does not aim to illustrate why snakes are dangerous but rather to educate about the differences between specific snake types. Choice D is incorrect as the essay does not discuss how animals survive in difficult environments, but instead focuses on snake markings and behaviors.
