1. Arrange the following fractions from least to greatest: 2/3, 1/2, 5/8, 7/9.

• A. 7/9, 5/8, 2/3, 1/2
• B. 1/2, 2/3, 5/8, 7/9
• C. 1/2, 5/8, 2/3, 7/9
• D. 7/9, 2/3, 5/8, 1/2

Correct answer: C

Rationale: To compare the fractions, it is beneficial to convert them to decimals or find a common denominator. When converted to decimals: 1/2 = 0.50, 5/8 = 0.625, 2/3 ≈ 0.666, and 7/9 ≈ 0.778. Therefore, the correct order from least to greatest is 1/2, 5/8, 2/3, 7/9. Choice A is incorrect because it places 7/9 first, which is the greatest fraction. Choice B is incorrect as it incorrectly lists the fractions. Choice D is incorrect as it starts with 7/9, which is the largest fraction instead of the smallest.

2. What is the function of the rib cage in the human body?

• A. To protect the digestive organs
• B. To protect the lungs and heart
• C. To support movement
• D. To regulate body temperature

Correct answer: B

Rationale: The rib cage plays a crucial role in protecting vital organs, specifically the lungs and heart, from external injuries. Choice A is incorrect because the rib cage does not primarily protect the digestive organs. Choice C is incorrect as the primary function of the rib cage is not to support movement, but to protect internal organs. Choice D is incorrect as regulating body temperature is not a function typically associated with the rib cage.

3. How many feet are in a mile?

• A. 1,000 ft
• B. 5,280 ft
• C. 2,000 ft
• D. 10,000 ft

Correct answer: B

Rationale: The correct answer is B: 5,280 feet in a mile. This is a standard conversion used in the Imperial system of measurement. Choice A, 1,000 ft, is incorrect as it is a common misconception and not the accurate conversion. Choice C, 2,000 ft, is also incorrect. Choice D, 10,000 ft, is significantly higher than the actual conversion and is incorrect. Remember, when converting miles to feet, the accurate value is 5,280 feet in a mile.

4. Which of the following is a compound sentence?

• A. Plague, generally not a major public health concern, actually continues to spread among rodent populations today, and it even occasionally makes its way into a human host.
• B. Modern archaeology, which seeks answers to humanity’s questions about its past, is significantly helped by new technologies.
• C. In the fight against obesity, countries around the world are imposing taxes on sodas and other sugary drinks in an effort to curb unhealthy habits.
• D. Because the assassination of President John F. Kennedy continues to haunt and fascinate Americans, new movies, books, and television series about it are released every year.

Correct answer: A

Rationale: A compound sentence consists of two or more independent clauses that are joined by coordinating conjunctions such as 'and,' 'but,' or 'or.' In choice A, the sentence contains two independent clauses separated by the coordinating conjunction 'and': 'Plague, generally not a major public health concern, actually continues to spread among rodent populations today' and 'it even occasionally makes its way into a human host.' Choice B is a complex sentence as it contains a dependent clause 'which seeks answers to humanity’s questions about its past' and an independent clause 'is significantly helped by new technologies.' Choice C is a simple sentence with one independent clause: 'In the fight against obesity, countries around the world are imposing taxes on sodas and other sugary drinks in an effort to curb unhealthy habits.' Choice D is a complex sentence with a dependent clause 'Because the assassination of President John F. Kennedy continues to haunt and fascinate Americans' and an independent clause 'new movies, books, and television series about it are released every year.'

5. Which of the following best describes the function of the pericardium?

• A. Regulating blood flow through valves within the heart.
• B. Acting as a protective sac surrounding the heart.
• C. Generating the electrical impulses for heart contractions.
• D. Transmitting electrical signals between the atria and ventricles.

Correct answer: B

Rationale: The pericardium is a double-layered sac that surrounds and protects the heart. Its main functions include preventing overfilling of the heart, providing a physical barrier against infection and inflammation, and reducing friction between the heart and surrounding structures. Choices A, C, and D do not accurately describe the function of the pericardium. Option B is the correct answer as it aligns with the protective and supportive role of the pericardium, distinguishing it from the functions attributed to choices A, C, and D.
