1. To the nearest whole number, what is the mass of one mole of sodium chloride?

• A. 36 g/mol
• B. 43 g/mol
• C. 58 g/mol
• D. 72 g/mol

Correct answer: C

Rationale: The molar mass of sodium chloride (NaCl) is calculated by adding the atomic masses of sodium (Na) and chlorine (Cl). The atomic mass of sodium is approximately 23 g/mol and chlorine is approximately 35.5 g/mol. Adding these two atomic masses gives us a molar mass of approximately 58 g/mol for sodium chloride (NaCl). Therefore, the correct answer is C, 58 g/mol. Choice A (36 g/mol) is incorrect as it does not account for the individual atomic masses of sodium and chlorine. Choice B (43 g/mol) and choice D (72 g/mol) are also incorrect as they do not reflect the accurate molar mass of sodium chloride.

2. Which term refers to someone who has come to settle in the United States?

• A. Immigrate
• B. Migrate
• C. Immigrant
• D. Emigrant

Correct answer: C

Rationale: The correct answer is 'C: Immigrant.' An immigrant is a person who comes to live permanently in a foreign country, such as the United States. Choice A, 'Immigrate,' refers to the action of entering a foreign country to live there. Choice B, 'Migrate,' means to move from one place to another. Choice D, 'Emigrant,' is someone who leaves their own country to settle permanently in another.

3. What is the primary function of the kidneys in the urinary system?

• A. To filter waste from the blood
• B. To produce urine
• C. To regulate blood pressure
• D. To maintain fluid balance

Correct answer: A

Rationale: The correct answer is A: 'To filter waste from the blood.' The primary function of the kidneys in the urinary system is to filter waste products and excess substances from the blood, forming urine, which is then excreted from the body. This process helps maintain the body's internal environment by regulating the balance of electrolytes, fluid levels, and eliminating metabolic waste products. Choices B, C, and D are incorrect because while the kidneys do produce urine, regulate blood pressure, and maintain fluid balance, their primary function within the urinary system is the filtration of waste from the blood.

4. What is the best description for the word operated in this sentence? Rural communities are increasingly taking ownership of their hospitals, which may be operated by administrative medical groups.

• A. Performing surgery
• B. In effect
• C. Managed and run
• D. Brought about

Correct answer: C

Rationale: In the context of the sentence provided, the word 'operated' is best described as 'managed and run.' This choice accurately reflects the idea that rural communities are taking ownership and control of their hospitals, which may be overseen and operated by administrative medical groups. The word 'operated' here implies the day-to-day management and functioning of the hospitals, making option C the most suitable description in this context. Choices A, B, and D are incorrect as they do not capture the essence of 'operated' in the context of managing and running the hospitals.

5. If 30% of a given number is 18, what is the full number?

• A. 60
• B. 30
• C. 40
• D. 45

Correct answer: A

Rationale: If 30% of a number is 18, you can find the full number by dividing 18 by 0.30 (the decimal equivalent of 30%). This calculation results in 60. Therefore, the full number is 60. Choice B (30) is the result if 30% of the number itself was calculated, not the full number. Choices C (40) and D (45) are incorrect and do not align with the given information.
