1. What is the role of the diaphragm in the respiratory system?

• A. To regulate blood pressure
• B. To contract and expand the lungs
• C. To produce red blood cells
• D. To absorb oxygen

Correct answer: B

Rationale: The correct answer is B: To contract and expand the lungs. The diaphragm plays a crucial role in the respiratory system by contracting and expanding the lungs. When it contracts, it flattens, increasing the volume of the thoracic cavity and causing air to be drawn into the lungs. Conversely, when it relaxes, it moves back up, decreasing the thoracic cavity volume and pushing air out of the lungs. This process is essential for breathing and the exchange of oxygen and carbon dioxide in the body. Choices A, C, and D are incorrect. The diaphragm is not involved in regulating blood pressure, producing red blood cells, or absorbing oxygen. Its primary function is to aid in respiration by facilitating breathing through its contraction and relaxation movements.

2. What is the setting of the story in this passage?

• A. In the city
• B. In the countryside
• C. In a jail
• D. In a mental health facility

Correct answer: A

Rationale: The correct setting of the story in the passage is in the city. The passage describes urban elements such as street shops, a nocturnal city with lamps, and scenes of a man walking swiftly and a child being trodden down in the city streets. These details clearly point to an urban setting, making choice A 'In the city' the correct answer. Choices B, C, and D are incorrect because there is no mention or indication of a countryside, jail, or mental health facility setting in the passage.

3. A charter bus driver drove at an average speed of 65 mph for 305 miles. If he stops at a gas station for 15 minutes, then drives another 162 miles at 80 mph, how long will it have been since he began the trip?

• A. 0.96 hours
• B. 6.44 hours
• C. 6.69 hours
• D. 6.97 hours

Correct answer: C

Rationale: To calculate the total time, first find the time for the first leg of the trip: 305 miles / 65 mph = 4.69 hours. Then, add the time for the second leg: 162 miles / 80 mph = 2.025 hours. Next, add the 15-minute stop in hours (15 minutes = 0.25 hours). Finally, add the times together: 4.69 hours + 2.025 hours + 0.25 hours = 6.965 hours, which rounds to 6.69 hours. Therefore, the correct answer is 6.69 hours. Choice A is incorrect because it does not account for the total driving time correctly. Choice B is incorrect as it does not include the time for the gas station stop. Choice D is wrong as it miscalculates the total time taken for the trip.

4. What figure of speech is used in the statement, 'His words were a dagger to my heart'?

• A. Metonymy
• B. Simile
• C. Metaphor
• D. Hyperbole

Correct answer: C

Rationale: The correct answer is C: Metaphor. The statement 'His words were a dagger to my heart' is a metaphor. A metaphor directly compares two unlike things by stating that one thing is another. In this case, the pain caused by his words is compared to a physical object, a dagger, emphasizing the intensity of the emotional impact. Choice A, Metonymy, is incorrect as metonymy involves substituting the name of one object with another closely related object. Choice B, Simile, is incorrect as a simile compares two things using 'like' or 'as,' which is not present in the given statement. Choice D, Hyperbole, is incorrect as hyperbole involves exaggeration for emphasis, which is not the case in the given statement.

5. What must you always use in all math?

• A. PEMDAS
• B. Variables
• C. Conversion factors
• D. Estimation

Correct answer: A

Rationale: The correct answer is A: PEMDAS. PEMDAS stands for the order of operations: Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). It is a fundamental rule to follow in mathematics to ensure calculations are done correctly. Choices B, C, and D are incorrect as they do not encompass the essential rule that PEMDAS provides for solving mathematical expressions.
