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 of the following is true of hypotheses of the form 'All x are y'?

• A. Something that is neither x nor y disproves the hypothesis.
• B. Something that is both x and y disproves the hypothesis.
• C. Something that is x but not y disproves the hypothesis.
• D. Something that is y but not x disproves the hypothesis.

Correct answer: D

Rationale: In hypotheses of the form 'All x are y,' the hypothesis is making a claim that all instances of x also fall under y. Therefore, if something is y but not x, it disproves the hypothesis because it contradicts the assertion that all x are y. Choice A is incorrect because something that is neither x nor y doesn't provide evidence against the hypothesis. Choice B is incorrect because if something is both x and y, it actually supports the hypothesis. Choice C is incorrect as something that is x but not y doesn't disprove the hypothesis, as it could still be consistent with the claim that all x are y.

3. The author of the passage describes Harriet Tubman's life as a slave to show

• A. why she wanted to escape slavery.
• B. why she was a spy during the Civil War.
• C. why she suffered from seizures.
• D. how she loved babies.

Correct answer: A

Rationale: The correct answer is A: 'why she wanted to escape slavery.' The author details Harriet Tubman's life as a slave to highlight the hardships and injustices she faced, motivating her to seek freedom for herself and others. Choice B is incorrect because while Tubman was a spy during the Civil War, the passage focuses on her experiences as a slave. Choice C is incorrect as the passage mentions her suffering from seizures due to a head injury, not as a primary reason for describing her life as a slave. Choice D is incorrect as the passage briefly mentions her experience as a nursemaid for a baby, but it does not focus on her love for babies as a key aspect of describing her life as a slave.

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 does the author imply will happen if people do not follow his suggestions?

• A. The author implies we will run out of resources in the next 10 years.
• B. The author implies water and energy prices will rise sharply in the near future.
• C. The author implies global warming and the depletion of natural resources will continue.
• D. The author implies local farmers will lose their farms.

Correct answer: C

Rationale: The author implies that neglecting the recommended actions will lead to the continued degradation of the environment and depletion of resources. The passage emphasizes the importance of being proactive in conserving resources to combat global warming and the depletion of natural resources. Choice A is incorrect because the author doesn't specify a timeframe for running out of resources. Choice B is incorrect as the focus is on environmental impact rather than economic consequences. Choice D is incorrect as the passage does not specifically mention the impact on local farmers.
