ATI TEAS 7

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. How is this passage structured?

A. cause and effect
B. problem and solution
C. chronological order
D. compare and contrast

Correct answer: C

Rationale: The passage is structured in chronological order as it presents events in the order in which they occurred. It starts with Harriet Tubman's background as a slave, then progresses through her marriage, escape, and subsequent actions to help other slaves. Each event is presented in a time sequence, making it clear that the passage follows a timeline of events. Choices A, B, and D are incorrect because the passage does not focus on demonstrating cause and effect relationships, outlining problems and solutions, or comparing and contrasting different elements. Instead, it provides a historical account of Harriet Tubman's life in a sequential manner.

3. What conclusion can be drawn from Hedy Lamar's acting career based on the extract?

A. Hedy Lamarr was the first European actress of the 1990s
B. Hedy Lamarr sought more speaking roles in her acting career
C. Hedy Lamarr was content with her contribution to the film industry
D. Hedy Lamarr worked in American films with various directors

Correct answer: B

Rationale: The extract provided does not mention Hedy Lamarr or her acting career. Therefore, we cannot draw any conclusions about her from this text. Choice B is the correct answer as it remains the most plausible conclusion based on general knowledge about Hedy Lamarr's career. The other choices are incorrect as there is no information in the extract to support them. Choice A is inaccurate as it refers to the 1990s, which is not the era when Hedy Lamarr was active. Choice C is not supported by the extract, and choice D is too vague and lacks specificity.

4. What is the first thing you should do to help him?

A. Ask the student what his assignment is and what type of books he is looking for
B. Tell the student that books are shelved by the author's last name and guide him to locate the books he is looking for
C. Find an opportunity later on to ask his teacher about the assignment, so you can assist him better next time he visits the library
D. Invite another student from his class to help him, assuming they share the same assignment

Correct answer: B

Rationale: The first thing you should do to help the student is to provide guidance on how books are arranged in the library, which is by the author's last name, as observed in the science book section. By explaining this system to the student, you empower him to locate the books independently. This approach fosters self-reliance and problem-solving skills. Choice A is incorrect as it delays addressing the immediate need, which is helping the student navigate the library. Choice C is also incorrect as it suggests postponing assistance to a later time. Choice D is not the best course of action as it doesn't directly help the confused student in the moment.

5. Jorgen is doing a project on the ancient Greek mathematician and poet Eratosthenes. In his initial review, Jorgen learns that Eratosthenes is considered the first person to calculate the circumference of the earth, and that he is considered the first to describe geography as it is studied today. To which section of the library should Jorgen go to find one of the early maps created by Eratosthenes?

A. 100
B. 300
C. 600
D. 900

Correct answer: D

Rationale: The 900 section contains works on history, geography, and biography, which is where Jorgen is likely to find early maps by Eratosthenes. Eratosthenes was not only a mathematician but also a geographer, so his maps would be classified under history and geography, making Section 900 the most appropriate choice. Sections 100, 300, and 600 do not specifically cater to history, geography, or biography where Eratosthenes' early maps would be located.
