1. What is the purpose of the passage?

• A. to inform
• B. to entertain
• C. to describe
• D. to persuade

Correct answer: A

Rationale: The main purpose of this passage is to inform readers about the role of skin coloration and markings in snakes. It explains how these markings help snakes hide from predators and how they can also indicate venomousness. The passage also provides examples such as the scarlet kingsnake to illustrate how some nonvenomous snakes mimic the appearance of venomous snakes for protection. This informative content aims to educate readers about the survival strategies of snakes, rather than entertain, describe, or persuade them.

2. Which of the following is an example of a flat bone?

• A. Femur
• B. Scapula
• C. Humerus
• D. Tibia

Correct answer: B

Rationale: The correct answer is B, the Scapula. Flat bones, such as the scapula, are thin, flattened bones that provide protection to internal organs and serve as attachment points for muscles. The other choices, femur, humerus, and tibia, are examples of long bones, which are characterized by their elongated structure and are primarily involved in supporting weight and facilitating movement.

3. What information should the author include to help clarify information in the passage?

• A. The fat content of yogurt.
• B. How much calcium is in fortified juice.
• C. Which leafy greens contain calcium.
• D. The definition of lactose intolerance.

Correct answer: D

Rationale: The author should include information on the definition of lactose intolerance to help readers understand the need for lactose-free alternatives within the milk group. This clarification would provide context for why lactose-free options are recommended and help individuals make informed choices based on their dietary needs. Choices A, B, and C, although related to the topic of calcium-rich foods, do not directly address the issue of lactose intolerance and its implications for choosing suitable dairy alternatives.

4. What is hemoglobin?

• A. an enzyme
• B. a protein
• C. a lipid
• D. an acid

Correct answer: B

Rationale: Hemoglobin is a protein found in red blood cells that plays a crucial role in transporting oxygen from the lungs to the tissues and organs in the body. It is composed of four protein subunits, each containing a heme group that binds to oxygen molecules. Choice A is incorrect as hemoglobin is not an enzyme, but rather a protein. Choice C is incorrect as hemoglobin is not a lipid, but a protein. Choice D is incorrect as hemoglobin is not an acid, but a protein.

5. The speaker addresses his audience as 'My Good Friends.' What kind of credibility does this salutation give to the speaker?

• A. The speaker is an employer addressing his employees, so the salutation is a way to bridge the gap between himself and his employees.
• B. The speaker's salutation is one from an entertainer to his audience, using friendly language to connect before a serious speech.
• C. The salutation gives the serious speech that follows a somber tone, as it is used ironically.
• D. The speech is one from a politician to the public, so the salutation is used to grab the audience's attention.

Correct answer: B

Rationale: The speaker's address of 'My Good Friends' implies a sense of warmth and familiarity, indicating that the speaker wants to establish a connection with the audience before delivering a serious speech. This type of salutation is often used by entertainers to engage the audience and create a friendly atmosphere conducive to effective communication. Choice A is incorrect because there is no indication of an employer-employee relationship. Choice C is incorrect as there is no indication of irony in the salutation. Choice D is incorrect as the salutation aims to create a connection rather than grab attention as a politician might.
