1. Which statement best describes the rate of change?

• A. Every day, the snow melts 10 centimeters.
• B. Every day, the snow melts 5 centimeters.
• C. Every day, the snow increases by 10 centimeters.
• D. Every day, the snow increases by 5 centimeters.

Correct answer: B

Rationale: The rate of change refers to how one quantity changes concerning another quantity. In this scenario, the rate of change is the amount of snow melting per day, which is 5 centimeters. This is determined by the slope of the graph, indicating a decrease in snow depth. Choices C and D incorrectly describe an increase in snow depth, while choice A exaggerates the rate of snow melting compared to the actual value of 5 centimeters per day.

2. What percentage of the total rainfall in this timeframe occurs during October?

• A. 0.135
• B. 0.151
• C. 0.169
• D. 0.177

Correct answer: B

Rationale: To calculate the percentage of rainfall that occurs during October, divide October's rainfall (4.5 inches) by the total rainfall (29.38 inches) and multiply by 100. So, (4.5 / 29.38) * 100 = 15.31%. Among the choices given, option B, 0.151, is the closest to this calculated percentage. Options A, C, and D are not correct as they do not match the accurate calculation based on the provided data.

3. 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.

4. The adrenal cortex produces a group of steroid hormones called corticosteroids. What is a MAJOR function of corticosteroids?

• A. Regulate insulin sensitivity and blood sugar levels
• B. Control blood pressure and electrolyte balance
• C. Stimulate the immune system and inflammatory response
• D. Promote growth and development during puberty

Correct answer: B

Rationale: Corticosteroids, produced by the adrenal cortex, primarily function to control blood pressure and electrolyte balance. One of the key corticosteroids, aldosterone, plays a crucial role in regulating sodium and potassium levels in the body. This regulation is essential for maintaining blood pressure and electrolyte balance. Choices A, C, and D are incorrect because corticosteroids do not primarily regulate insulin sensitivity and blood sugar levels, stimulate the immune system and inflammatory response, or promote growth and development during puberty. While corticosteroids can have effects on insulin sensitivity, immune response, and growth, their major role is in maintaining blood pressure and electrolyte balance.

5. 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.
