1. What is the function of the lungs in the respiratory system?

• A. To filter blood
• B. To exchange gases
• C. To produce energy
• D. To remove waste products

Correct answer: B

Rationale: The correct function of the lungs in the respiratory system is to exchange gases. The lungs facilitate the exchange of oxygen and carbon dioxide between the air we breathe in and the blood, ensuring oxygen is absorbed and carbon dioxide is removed during respiration. Choice A is incorrect as the kidneys, not the lungs, filter blood. Choice C is incorrect as energy production primarily occurs in cells, not in the lungs. Choice D is incorrect as waste removal, such as the excretion of carbon dioxide, is a function of the lungs, but the primary function is the exchange of gases.

2. A nit is a kind of _______.

• A. Abscess
• B. Bandage
• C. Parasite
• D. Infection

Correct answer: C

Rationale: Correct! A nit is the egg of a parasitic insect, such as a louse. This makes 'Parasite' the correct answer. An abscess (Choice A) is a swollen area within body tissue containing an accumulation of pus. A bandage (Choice B) is a strip of material used to cover and protect a wound. An infection (Choice D) is the invasion and multiplication of microorganisms in body tissues.

3. If 9 out of 75 band members missed practice, what percentage of band members missed practice?

• A. 10%
• B. 12%
• C. 15%
• D. 18%

Correct answer: B

Rationale: To calculate the percentage of band members who missed practice, divide the number of members who missed practice (9) by the total number of band members (75) and multiply by 100. (9/75) * 100 = 12%. Therefore, 12% of the band members missed practice. Choice A (10%) is incorrect because it is not the correct calculation result. Choices C (15%) and D (18%) are also incorrect as they do not reflect the accurate percentage of band members who missed practice.

4. What is the main function of the large intestine?

• A. Absorption of nutrients
• B. Absorption of water
• C. Secretion of digestive enzymes
• D. Breaking down fats

Correct answer: B

Rationale: The main function of the large intestine is the absorption of water and electrolytes from indigestible food residues, helping to form solid waste (feces) for elimination. It mainly reabsorbs water and compacts the remaining material into feces, playing a crucial role in maintaining fluid balance in the body. Choices A, C, and D are incorrect because absorption of nutrients primarily occurs in the small intestine, secretion of digestive enzymes mainly occurs in the stomach and small intestine, and breaking down fats primarily occurs in the small intestine with the help of bile from the liver and enzymes.

5. What is the best description of an audit check?

• A. A restraint on appraisals
• B. A payment for inventory
• C. A test of hearing
• D. A review or inspection

Correct answer: D

Rationale: An audit check is a process of reviewing and inspecting financial records, transactions, or processes to ensure accuracy and compliance with established guidelines. It involves examining information systematically and thoroughly to verify its completeness and reliability. Option D, "A review or inspection," best describes an audit check. Choices A, B, and C are incorrect as they do not relate to the process of auditing financial records for accuracy and compliance.
