TEAS Reading Practice Questions

1. Which detail from the passage supports the conclusion that the passage takes place in the 21st century?

A. His office was on the thirtieth floor, far too high to get much more than a faint glow from the street lights below.
B. Shia froze, as if he were caught by the gaze of Medusa.
C. He sent his boss a single text message before turning over and trying to force himself to sleep.
D. Shia didn't stop running until he had burst the ground floor exit to the parking garage and found his car.

Correct answer: C

Rationale: The correct answer is C. The reference to sending a text message in the passage is a clear indication of the 21st century. This action of sending a text message is a modern communication method commonly associated with contemporary times. Choices A, B, and D do not provide any specific details or actions that distinctly tie them to the 21st century. Choice A focuses on the location of an office, which does not inherently place the passage in a specific time period. Choice B uses a metaphorical reference to Medusa, which is a mythological figure not limited to any particular era. Choice D describes a scene involving running to a parking garage, which could occur in various time periods without indicating a specific century.

2. Which property of a wave remains constant when the wave enters a different medium?

A. Frequency
B. Wavelength
C. Amplitude
D. Speed

Correct answer: A

Rationale: When a wave enters a different medium, its frequency remains constant. Frequency is an intrinsic property of the wave determined by its source, and it does not change when transitioning between different mediums. On the other hand, wavelength, amplitude, and speed of the wave can all be altered when the wave moves from one medium to another. Wavelength is dependent on the speed of the wave and can change when entering a different medium due to differences in propagation speed. Amplitude can also change as it is influenced by factors like energy loss or gain at the boundary of the mediums. Speed, determined by the medium's properties, typically changes when a wave transitions between different mediums due to variations in the medium's density and elasticity.

3. Which of the following describes a real-world situation that could be modeled by?

A. Courtney charges a $12 fee plus $2 per hour to babysit. Kendra charges a $10 fee plus $5 per hour. Write an equation to find the number of hours for which the two charges are equal.
B. Courtney charges a $2 fee plus $12 per hour to babysit. Kendra charges a $5 fee plus $10 per hour. Write an equation to find the number of hours for which the two charges are equal.
C. Courtney charges a $12 fee plus $2 to babysit. Kendra charges a $10 fee plus $5 to babysit. Write an equation to find the number of hours for which the two charges are equal.
D. Courtney charges $10 plus $2 per hour to babysit. Kendra charges $12 plus $5 per hour. Write an equation to find the number of hours for which the two charges are equal.

Correct answer: A

Rationale: In the given situation, Courtney charges a $12 fee plus $2 per hour to babysit, represented by the equation: 12 + 2h where h is the number of hours. Kendra charges a $10 fee plus $5 per hour, represented by the equation: 10 + 5h. To find the number of hours for which the two charges are equal, we set the two equations equal to each other: 12 + 2h = 10 + 5h. Solving for h gives h = 2. This means that the charges are equal after 2 hours of babysitting. Choice B is incorrect because the fee and hourly rates for Courtney and Kendra are reversed, leading to an incorrect equation. Choices C and D are incorrect as they do not accurately represent the given scenario of fees and hourly rates for babysitting by Courtney and Kendra.

4. What is the mode of the numbers in the distribution shown in the table?

A. 1
B. 2
C. 3
D. 4

Correct answer: A

Rationale: The mode of a set of numbers is the value that appears most frequently. In the distribution shown in the table, the number '1' occurs more times than any other number, making it the mode. Choices B, C, and D are incorrect because they do not represent the number that occurs most frequently in the dataset.

5. What does antidiuretic hormone (ADH) help the kidneys regulate?

A. Acid-base balance
B. Blood pressure
C. Urine output by controlling water reabsorption
D. All of the above

Correct answer: C

Rationale: Antidiuretic hormone (ADH) helps the kidneys regulate urine output by controlling water reabsorption. ADH acts on the kidneys to increase the reabsorption of water, leading to a decrease in urine output. This helps the body conserve water and maintain proper fluid balance. ADH primarily affects urine output by controlling water reabsorption and does not directly regulate acid-base balance or blood pressure. Therefore, choices A and B are incorrect because ADH does not directly influence acid-base balance or blood pressure.
