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. Which of the following statements represents an exaggerated claim in support of the argument presented in this passage?

A. In the United States, the foreign language requirement for high school graduation varies depending on the state.
B. Studying a foreign language is crucial for success in the global economy.
C. High school graduates with foreign language credits have a higher college acceptance rate.
D. Students who did not study a foreign language are completely unable to secure any job.

Correct answer: D

Rationale: The correct answer is D because it is an exaggerated claim to state that students who did not study a foreign language are completely unable to secure any job. While proficiency in a foreign language may enhance job prospects, it is unrealistic to suggest that not studying one would render someone unemployable. Choice A provides a factual statement about the variation in foreign language requirements, so it cannot be considered an exaggeration. Choices B and C highlight the increasing importance of foreign language skills and the benefits of having them, which are supported by trends and studies. These choices may be debatable, but they are not exaggerated claims.

3. What prompted Hedy Lamarr to take up inventing?

A. Boredom from her film roles lacking spoken lines
B. Formal training in engineering
C. Her successful inventions like the radio signal technology
D. Working with Howard Hughes' aviation team

Correct answer: A

Rationale: Hedy Lamarr took up inventing due to boredom from her film roles lacking spoken lines. The extract mentions that to relieve her boredom, Lamarr turned to inventing after her film roles did not provide much dialogue.

4. Which of the following evidence from the passage supports the inference that providing nap rooms at work can improve employee productivity?

A. In the recent company-wide audits, many employees have reported fatigue at work.
B. According to a 2008 study, napping for 60 minutes helped improve verbal memory, motor skills, and perceptual learning better than caffeine.
C. Many successful companies have adopted the practice of work naps, in industries like tech, manufacturing - even NASA!
D. Starting today, we will be providing a designated nap room in each office building near the gym and cafeteria to help employees take care of their bodies and minds, so they can be happier, healthier, and more productive.

Correct answer: B

Rationale: The correct answer is B because the evidence from the 2008 study mentioned in the passage supports the inference that napping for 60 minutes can improve verbal memory, motor skills, and perceptual learning better than caffeine. This indicates that providing nap rooms at work can lead to improved productivity by enhancing cognitive functions. Choice A talks about the fatigue reported by employees but does not directly link it to productivity improvement. Choice C mentions that many successful companies have adopted the practice of work naps but does not specifically tie it to productivity enhancement. Choice D states the intention to provide nap rooms for employees but does not provide direct evidence of productivity improvement.

5. Based on the passage, which of the following is the most logical conclusion?

A. The professor will offer another extra credit project later in the semester.
B. Students who choose two extra-credit options will be given double the extra credit.
C. Students who choose the third option will receive one quarter of the offered extra credit.
D. Students are most likely to earn maximum extra credit by choosing the first option.

Correct answer: D

Rationale: Based on the passage, the most logical conclusion is that students are most likely to earn the maximum extra credit by choosing the first option. The first option provides an extra credit project worth 150% of the point value of the essay exam, giving students more than enough chance to make up the difference and raise their overall score. The second and third options also offer the same 150% extra credit, but they involve more subjective scoring or group work, respectively, which may not ensure maximum extra credit. Therefore, choosing the first option is the best way for students to earn the most extra credit.
