1. 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.

2. Which detail from the passage best supports the conclusion that the little girl is no older than three years old?

• A. For lunch, she likes ham and cheese (torn into bites), yogurt, raisins, applesauce, peanut butter sandwiches in the fridge drawer, or any combo of these.
• B. It’s fine if you want to go somewhere, just leave us a note of where you are.
• C. As for nap, try after lunch. She may not sleep, but try anyway.
• D. Turn on music in her room, leave her in her crib with a dry diaper and bottle to try to sleep.

Correct answer: D

Rationale: The detail from choice D, 'Turn on music in her room, leave her in her crib with a dry diaper and bottle to try to sleep,' best supports the conclusion that the little girl is no older than three years old. This detail suggests that the child is still using a crib for sleeping, a common practice for infants and toddlers. Additionally, the mention of a bottle indicates that the child is likely young, as older children typically do not use bottles for sleep. Choices A, B, and C do not provide specific details related to the child's age like the mention of a crib and a bottle does in choice D.

3. What is the main idea of the second paragraph?

• A. One hairy monkey proves the hypothesis 'All monkeys are hairy.'
• B. The same piece of evidence can both confirm and disconfirm a hypothesis.
• C. Confirming and disconfirming evidence affect hypotheses differently.
• D. The scientific method is not a failsafe method for arriving at objective truth.

Correct answer: C

Rationale: The main idea of the second paragraph is that confirming and disconfirming evidence can affect hypotheses differently, as stated in the passage - 'Single pieces of evidence then, seem to affect a given hypothesis in radically different ways.' Choice A is incorrect because the paragraph discusses how single pieces of evidence affect hypotheses, not that one hairy monkey proves a hypothesis. Choice B is incorrect as the paragraph focuses on the different effects of evidence on hypotheses, rather than its ability to confirm and disconfirm simultaneously. Choice D is incorrect as the paragraph does not primarily discuss the scientific method's failings but rather the impact of evidence on hypotheses.

4. Which of the following best describes the passage?

• A. Narrative
• B. Persuasive
• C. Expository
• D. Technical

Correct answer: B

Rationale: The correct answer is B: 'Persuasive.' The passage aims to persuade readers against smoking by presenting facts and arguments to convince them of the harmful effects of smoking. It highlights the negative consequences of smoking, such as containing carcinogens and toxins, causing various types of cancer, and leading to addiction. The passage also emphasizes the health risks and societal costs associated with smoking. Choices A, C, and D are incorrect because the passage is not a narrative (storytelling), expository (informative), or technical (specialized information) piece; instead, it focuses on convincing the audience to avoid smoking.

5. What is the author's purpose in discussing aquatic insects in relation to those that spend their entire lives in the air?

• A. To emphasize the adaptability and complexity of insect life cycles.
• B. To compare aquatic insects with those that remain airborne.
• C. To highlight the unique features of insects that live in both environments.
• D. To question the validity of studying insects that live in only one environment.

Correct answer: A

Rationale: The author's purpose in discussing aquatic insects in relation to those that spend their entire lives in the air is to emphasize the adaptability and complexity of insect life cycles. The author highlights how some insects transition between aquatic and aerial environments, showcasing the diverse strategies and features these insects possess to thrive in different habitats. Choice B is incorrect because the author is not solely comparing aquatic insects with those that remain airborne, but rather exploring their adaptability. Choice C is incorrect as the focus is not on highlighting unique features but on showcasing the transition between environments. Choice D is incorrect as the author is not questioning the validity of studying insects in only one environment but rather demonstrating the fascinating dual-life cycles of certain insects.
