1. What is the meaning of the word 'emitting' as it is used in the second paragraph?

• A. Repelling
• B. Releasing
• C. Closing
• D. Charging

Correct answer: B

Rationale: In the context provided, 'emitting' means releasing, specifically referring to the electric currents being released in the body. The passage describes how electric currents are constantly being emitted in the body and can be detected on the body's surface, ultimately recorded by an electrocardiograph. This process is about the release of electric impulses, making 'releasing' the correct interpretation. Choice A, 'Repelling,' implies pushing away, which is not the intended meaning in this context. Choice C, 'Closing,' and Choice D, 'Charging,' do not align with the context of electric currents being emitted.

2. What is the overall tone of the essay?

• A. Informative
• B. Insensitive
• C. Grim
• D. Uplifting

Correct answer: C

Rationale: The passage discusses the challenges and symptoms associated with sickle-cell anemia, portraying a somber and serious tone. The descriptions of persistent pain, difficulties, and the impact on individuals' lives make the overall tone fairly grim. The essay focuses on the hardships faced by individuals with sickle-cell anemia, highlighting the severity of the disease. Choices A, B, and D are incorrect because the tone of the essay is not informal, insensitive, or uplifting. It is important to consider the language used, the subject matter, and the overall emotional impact of the text to determine the tone accurately.

3. What is the meaning of the word serendipity as it is used in the first paragraph?

• A. Chance
• B. Persistence
• C. Foreboding
• D. Expertise

Correct answer: A

Rationale: The word "serendipity" refers to a fortunate coincidence or chance, describing how Beto Pérez invented Zumba accidentally.

4. How does insomnia affect intellectual abilities?

• A. Causes a deficit in memory, concentration, and attention.
• B. Improves mental alertness.
• C. Boosts concentration levels.
• D. Has no effect on intellectual abilities.

Correct answer: A

Rationale: Insomnia affects intellectual abilities by causing a deficit in memory, concentration, and attention. The passage highlights that lack of sleep impacts memory, attention, and concentration, leading to feelings of irritation or depression. Therefore, choice A is correct. Choices B, C, and D are incorrect because they do not align with the negative impact insomnia has on intellectual abilities as described in the passage.

5. What is the best summary of the passage?

• A. Electric currents within the body are due to electrostatic charges set off by the heart. Medical staff are trained to recognize any abnormalities within the heart.
• B. Every individual has unique electric currents on the surface of the body. The ECG measures and records these electric currents.
• C. The ECG systematically and rather quickly measures the stages at which the 'wave of excitation' occurs within the heart and records them. This wave has three distinct steps that spread from the SA node to the AV node.
• D. The ECG measures the electric currents within the body. These currents are detected on the surface of the body when the body is connected to an amplifier.

Correct answer: C

Rationale: The correct summary of the passage is option C. The passage explains how the ECG systematically measures and records the 'wave of excitation' that occurs within the heart in three distinct steps, spreading from the SA node to the AV node. This summary effectively captures the main focus of the passage. Option A is incorrect because it only mentions the detection of electric currents in the body and recognizing abnormalities by medical staff, missing the key information about the 'wave of excitation' and its stages. Option B is incorrect as it focuses solely on the measurement and recording of unique electric currents on the body's surface, neglecting the specific process described in the passage. Option D is also incorrect as it provides a general description of how the ECG measures electric currents without emphasizing the specific stages of the 'wave of excitation' as detailed in the passage.
