1. 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.

2. The word 'massive' in line 4 is closest in meaning to?

• A. Dense
• B. Impressive
• C. Huge
• D. Unavoidable

Correct answer: C

Rationale: In the context of the passage, 'massive' is used to describe the size of the collision that formed the Moon, indicating something very large or huge. While 'dense' means closely compacted, 'impressive' means evoking admiration, 'huge' is the closest synonym to 'massive' in this context. 'Unavoidable' does not convey the same meaning as 'massive' in this sentence, making it incorrect.

3. Choose the best summary of the passage about microbes.

• A. Scientists have discovered the importance of certain bacteria for a well-functioning immune system, especially in defending against pathogens. The colonization of microbes in the body begins at birth, with the immune system relying on these bacteria for proper function.
• B. The passage discusses the role of bacteria in the development of the human immune system. It highlights that the body supports various microorganisms crucial for immunity, starting from birth. The presence of harmless bacteria is essential for the immune system to work effectively.
• C. The body hosts a vast number of microorganisms critical for immune system development. Harmless bacteria are necessary for the immune system to defend against pathogens effectively. Early research shows promising results in fecal bacteriotherapy for restoring the immune system's ability to fight off harmful invaders.
• D. Microbes play a pivotal role in human health, particularly in immune system development. The introduction of healthy bacteria is essential for the immune system to function correctly. Fecal bacteriotherapy is a novel approach to reintroducing beneficial bacteria into a compromised colon to enhance immune response.

Correct answer: C

Rationale: The correct answer is C. The passage emphasizes the importance of certain bacteria for a properly functioning immune system. It discusses how harmless bacteria play a crucial role in defending the body against pathogens. Choice A is incorrect as it focuses on the immune system's response to certain types of bacteria in lower organisms, not the overall importance of bacteria for immunity. Choice B is incorrect as it mainly discusses bacteriotherapy in relation to the reconstruction of a damaged colon, rather than the broader role of bacteria in immune system health. Choice D is incorrect as it only talks about the process of replacing harmful bacteria with harmless ones, missing the key point about the necessity of certain bacteria for immune system function.

4. What is the meaning of the word viable as used in the last paragraph?

• A. Reasonable
• B. Unresolved
• C. Contemporary
• D. Consistent

Correct answer: A

Rationale: In the context of the passage, "viable" means reasonable or feasible, referring to the acceptability of acupuncture as a treatment option based on the study's results. This definition aligns with the implications made in the conclusion of the study, thus supporting option A.

5. What is the author’s primary purpose in writing the essay?

• A. To persuade the reader to have an ECG
• B. To entertain the reader with a heartwarming story
• C. To inform the reader how an electrocardiograph reads the electric currents emitted by the heart
• D. To analyze the difference between the SA node and the AV node

Correct answer: C

Rationale: The author's primary purpose in writing the essay is to inform the reader about how an electrocardiograph reads the electric currents emitted by the heart. Choice A is incorrect because there is no attempt to persuade the reader to have an ECG. Choice B is incorrect because the essay is focused on providing information rather than entertaining with a heartwarming story. Choice D is incorrect as the essay does not primarily analyze the difference between the SA node and the AV node; instead, it focuses on explaining how an electrocardiograph reads electric currents from the heart.
