1. What is the main idea of the passage about MRSA?

• A. Methicillin-resistant Staphylococcus aureus (MRSA) is a significant problem both within and outside of hospitals, and there are ways to mitigate the risk.
• B. A new textile made of nanomaterials could significantly reduce the spread of hospital-associated MRSA infections.
• C. There are multiple strains of MRSA, and they pose various risks beyond just fatality.
• D. MRSA is a significant problem both within and outside of hospitals, but there are ways to mitigate the risk.

Correct answer: D

Rationale: The main idea of the passage is that MRSA is a significant issue both within and outside of hospitals. It highlights the challenges posed by MRSA, including its resistance to antibiotics, high mortality rates, and widespread presence in various settings. While the development of new technologies like nanomaterial textiles shows promise in reducing hospital-associated MRSA, the passage also emphasizes the importance of practicing good hygiene to prevent community-associated MRSA infections. Choices A, B, and C are incorrect because they do not capture the comprehensive overview of MRSA provided in the passage. Choice A encompasses the main idea by emphasizing the significance of MRSA and ways to mitigate the risk. Choice B focuses on a specific solution rather than the broader issue of MRSA. Choice C is incorrect as it oversimplifies the risks associated with MRSA strains by only mentioning fatality.

2. A rock has a volume of 6 cm3 and a mass of 24 g. What is its density?

• A. 4 g/cm3
• B. 4 cm3/g
• C. 144 g/cm3
• D. 144 cm3/g

Correct answer: A

Rationale: Density is calculated by dividing the mass of an object by its volume. In this case, the mass of the rock is 24 g and its volume is 6 cm3. By dividing 24 g by 6 cm3, we find that the density of the rock is 4 g/cm3. Choice A is the correct answer because density is expressed in units of mass per unit volume (g/cm3). Choice B is incorrect as it represents the reciprocal of density. Choices C and D are significantly higher values and do not match the calculated density of the rock.

3. What is the meaning of the word diligent as used in the last paragraph about Sickle-Cell Anemia?

• A. Dispersed.
• B. Incensed.
• C. Painstaking.
• D. Demanding.

Correct answer: C

Rationale: In the context of sickle-cell anemia, diligent means painstaking, indicating the careful and thorough approach required to manage the disease. The passage highlights the challenges of managing the symptoms of sickle-cell anemia and the need for meticulous and conscientious care. Choices A, B, and D are incorrect. 'Dispersed' and 'Incensed' do not align with the meaning of diligent in this context. 'Demanding' does not capture the essence of the careful and thorough care needed to manage the disease.

4. Which muscle is responsible for breathing?

• A. Diaphragm
• B. Intercostal muscles
• C. Rectus abdominis
• D. Pectoralis major

Correct answer: A

Rationale: The diaphragm is the primary muscle responsible for breathing. It is a large, dome-shaped muscle located at the base of the chest cavity. When it contracts, it flattens, increasing the volume of the chest cavity and causing inhalation. When it relaxes, it returns to its dome shape, decreasing the volume of the chest cavity and causing exhalation. The intercostal muscles, located between the ribs, assist the diaphragm in breathing by expanding and contracting the chest cavity. The rectus abdominis and pectoralis major are not directly involved in the process of breathing.

5. What sentence should replace the following incorrect sentence? 'This door to remain unlocked during business hours.'

• A. This business must have the door unlocked at all times.
• B. This door to remain unclosed while open.
• C. This sentence is corrected as written.
• D. This door will remain unlocked when the business is open.

Correct answer: D

Rationale: The original sentence is incorrect due to awkward phrasing. Choice D, 'This door will remain unlocked when the business is open,' provides a clear and concise correction, specifying that the door should be unlocked only when the business is open. Choices A and B do not address the timing aspect of unlocking the door, making them incorrect. Choice C is incorrect as the original sentence needs a revision to clarify the intended meaning.
