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. What can the reader conclude from the passage above?

A. The kingsnake is dangerous to humans.
B. The coral snake and the kingsnake are both hunted by the same predators.
C. It's safe to handle snakes in the woods because you can easily tell whether they're poisonous.
D. The kingsnake changes its markings when hawks or eagles are close by.

Correct answer: B

Rationale: The correct answer is B. The passage explains that the kingsnake mimics the venomous coral snake's markings to deter predators, particularly hawks and eagles, which cannot differentiate between the two species. This implies that both the coral snake and the kingsnake face similar threats from predators in their shared habitat. Choice A is incorrect because the passage clearly states that the kingsnake is nonvenomous, so it is not dangerous to humans. Choice C is incorrect as the passage highlights that not all snakes with flashy markings are venomous, emphasizing the need for caution. Choice D is incorrect as there is no mention of the kingsnake changing its markings in response to the presence of hawks or eagles in the passage.

3. What is the author’s likely purpose in writing this passage about Queen Victoria?

A. To persuade the reader to appreciate the accomplishments of Queen Victoria, especially when placed against the failures of her forebears.
B. To introduce the historical impact of the Victorian Era by introducing to readers the queen who gave that era its name.
C. To explain how small events in history placed an unlikely princess in line to become the queen of England.
D. To indicate the role that King George III’s many sons played in changing the history of England.

Correct answer: C

Rationale: The correct answer is C. The author's purpose in writing this passage is to explain how small events in history led to an unlikely princess, Princess Alexandrina Victoria, becoming the queen of England. The passage discusses the family background of Queen Victoria and how a series of events, including the lack of legitimate heirs from King George III's sons, ultimately paved the way for her ascension to the throne. Choice A is incorrect because the passage is more focused on presenting historical events rather than persuading readers to appreciate Queen Victoria's accomplishments. Choice B is also incorrect as the passage does mention the Victorian Era but is primarily centered around Queen Victoria's personal journey to the throne. Choice D is incorrect as the passage does briefly mention King George III's sons, but it does not primarily focus on their role in changing the history of England.

4. During the Great Emu War, which of the following events happened immediately after the conflict resumed in mid-November?

A. Military efforts became ineffective
B. The Australian government launched the initial assault
C. The military withdrew
D. Emus resorted to guerrilla tactics

Correct answer: D

Rationale: The correct answer is D. According to the extract, emus resorted to guerrilla tactics during the Great Emu War. This choice aligns with the information provided, indicating that the emus changed their tactics in response to the conflict. Choices A, B, and C are incorrect as there is no mention in the extract or historical context of military efforts becoming ineffective, the Australian government launching an initial assault, or the military withdrawing immediately after the conflict resumed in mid-November.

5. A 'competitive salary' is one that is

A. Much less than salaries offered for comparable jobs
B. Much greater than salaries offered for comparable jobs
C. Similar to the average salary offered for comparable jobs
D. Impossible to compare to the salaries offered for comparable jobs

Correct answer: C

Rationale: A competitive salary is one that is similar to the average salary offered for comparable jobs. In the context of the job advertisement provided, a competitive salary is typically in line with what other employers are paying for similar positions to attract and retain the best talent in the industry. Choice A is incorrect because a competitive salary is not 'much less' than salaries offered for comparable jobs; it aims to be competitive. Choice B is incorrect as a competitive salary is not 'much greater' than salaries offered for comparable jobs; it aims to be fair and competitive. Choice D is incorrect as a competitive salary is not 'impossible to compare to' the salaries offered for comparable jobs; it is meant to be competitive and aligned with industry standards.
