TEAS Reading Practice Test

1. What role do the spiracles play in the respiration of the insects described in the passage?

A. They allow insects to breathe atmospheric air even when submerged.
B. They protect the insect's internal organs from water pressure.
C. They filter oxygen from the water for underwater breathing.
D. They are used to expel carbon dioxide from the body.

Correct answer: A

Rationale: The spiracles in insects serve the crucial function of allowing them to breathe atmospheric air even when submerged. The passage explains that insects have a system of branching air-tubes that carry atmospheric air with oxygen to all tissues. The air enters these tubes through paired air-holes or spiracles, enabling insects to respire even when they are underwater. Choices B, C, and D are incorrect because the spiracles do not protect internal organs from water pressure, filter oxygen from water for underwater breathing, or expel carbon dioxide from the body. The primary role of spiracles is to facilitate respiration by allowing insects to access atmospheric air.

2. 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.

Correct answer: A

Rationale: The 'nature of the fairy tale genre' in Passage 2 refers to the representation of basic human experiences.

Choices A, B, and D do not follow the correct chronological order as depicted in the passage.
