TEAS Reading Questions
1. Using the same reasoning as that in the passage, an automobile with eighteen wheels does what to the following hypothesis: 'All automobiles have only four wheels'?
- A. It proves the hypothesis.
- B. It raises the hypothesis's probability.
- C. It disproves the hypothesis.
- D. It decreases the hypothesis's probability.
Correct answer: D
Rationale: An automobile with eighteen wheels contradicts the hypothesis that 'All automobiles have only four wheels.' This contradiction reduces the probability that the hypothesis is true. The hypothesis is not proven by the presence of an eighteen-wheel automobile, nor does it raise the probability of the hypothesis being true. Instead, it directly challenges the hypothesis, leading to a decrease in its probability of being correct.
2. Which of the following statements regarding the pericardium is not correct?
- A. It allows for the heart to work in a relatively friction-free environment
- B. It is a single-walled layer around the heart
- C. It prevents overfilling of the heart with blood
- D. It protects and anchors the heart
Correct answer: B
Rationale: The correct statement about the pericardium is that it is double-walled, not single-walled. Choice A is correct because the pericardium does allow the heart to work in a relatively friction-free environment, reducing friction during heartbeats. Choice C is correct as the pericardium helps prevent the overfilling of the heart with blood. Choice D is also correct as the pericardium serves to protect and anchor the heart in place within the chest cavity.
3. What is the role of surfactant in the respiratory system?
- A. To trap dust particles
- B. To increase lung compliance
- C. To produce mucus
- D. To generate oxygen during respiration
Correct answer: B
Rationale: The correct answer is B: To increase lung compliance. Surfactant is a substance produced by type II alveolar cells in the lungs that reduces surface tension in the alveoli. This reduction in surface tension helps to increase lung compliance, making it easier for the lungs to expand and contract during breathing. Improved lung compliance is essential for efficient gas exchange in the respiratory system, facilitating oxygen uptake and carbon dioxide removal. Choices A, C, and D are incorrect because surfactant does not trap dust particles, produce mucus, or generate oxygen during respiration. Instead, its primary function lies in reducing surface tension to prevent alveolar collapse and improve lung compliance for optimal gas exchange.
4. At the beginning of the day, Xavier has 20 apples. At lunch, he meets his sister Emma and gives her half of his apples. After lunch, he stops by his neighbor Jim’s house and gives him 6 of his apples. He then uses ¾ of his remaining apples to make an apple pie for dessert at dinner. At the end of the day, how many apples does Xavier have left?
- A. 4
- B. 6
- C. 2
- D. 1
Correct answer: D
Rationale: Xavier starts with 20 apples. He gives half of his apples to his sister Emma, which is 20 ÷ 2 = 10 apples, leaving him with 10 apples. Then, he gives 6 apples to his neighbor Jim, leaving him with 10 - 6 = 4 apples. Using ¾ of his remaining 4 apples for the pie, he uses 3/4 x 4 = 3 apples. Therefore, he has 4 - 3 = 1 apple left at the end of the day. Choice D, 1 apple, is the correct answer. Choices A, B, and C are incorrect because Xavier ends up with 1 apple remaining, not 4, 6, or 2.
5. To which section of the library should Jorgen go to locate these works?
- A. 100
- B. 200
- C. 700
- D. 800
Correct answer: D
Rationale: Jorgen should go to Section 800 to locate The Iliad and The Odyssey by Homer. These works are literary masterpieces and would be categorized under literature in the library. While sections 100, 200, and 700 cover Philosophy and psychology, Religion, and Arts and recreation respectively, they are not the most suitable sections for finding works of literature like The Iliad and The Odyssey.
