1. What fact is stated about the Amazon Rainforest in the passage?

• A. The Amazon Rainforest is shrinking rapidly.
• B. The Amazon Rainforest is home to diverse species.
• C. The Amazon Rainforest is unaffected by human activity.
• D. The Amazon Rainforest contains few animals.

Correct answer: B

Rationale: The correct answer is B. The passage highlights the incredible biodiversity of the Amazon Rainforest, emphasizing its diverse species of plants and animals. The passage describes the rainforest as home to over 2,000 birds and mammals, with one in every five birds in the world living there. It also mentions the vast variety of insects, trees, and plants present in the rainforest, showcasing its rich ecosystem. Choice A is incorrect as the passage does not directly state that the Amazon Rainforest is shrinking rapidly, although it does mention the dangers it faces. Choice C is incorrect as the passage clearly indicates that human activity, such as deforestation, poses a significant threat to the rainforest. Choice D is incorrect as the passage provides evidence of a high number of animals inhabiting the Amazon Rainforest.

2. Which statement from the selection presents a fact rather than an opinion?

• A. One of the worst voice qualities is harshness
• B. Harsh voice qualities usually come from too much tension in the throat and jaw
• C. Your voice will sound unpleasant if it is shrill, grating, hard, piercing, brassy, too loud, or too nasal
• D. Because tension occurs in higher pitched voices, women tend to have shriller voices than men, which usually makes them less desirable public speakers, newscasters, or political candidates

Correct answer: B

Rationale: Statement B, 'Harsh voice qualities usually come from too much tension in the throat and jaw,' presents a fact rather than an opinion. This statement provides a clear and objective observation about the potential cause of harsh voice qualities, based on physical tension in specific areas of the body, which can be objectively measured and identified. Choice A is an opinion as it states 'One of the worst voice qualities is harshness' without providing a verifiable basis. Choice C lists subjective descriptors of an unpleasant voice without stating a definite cause. Choice D introduces a gender-based assertion about voice quality, making it an opinion rather than a factual observation.

3. In this passage, which of the following is not mentioned as a role of HGH in the human body?

• A. Regulating the metabolism.
• B. Stimulating the immune system.
• C. Regulating leptin, an appetite-controlling hormone.
• D. Facilitating calcium retention.

Correct answer: C

Rationale: The correct answer is C: Regulating leptin, an appetite-controlling hormone. In the provided passage, it is stated that human growth hormone (HGH) is essential for regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. However, leptin is not mentioned as directly regulated by HGH. Instead, the passage discusses how inadequate sleep can lead to lowered levels of leptin, affecting appetite control. Choices A, B, and D are all roles of HGH explicitly mentioned in the passage, making them incorrect answers. Therefore, C is the correct choice as it was not directly linked to HGH in the passage.

4. Which of the following is not listed as a detail in the passage about A Short History of the CDC?

• A. Where the organization began.
• B. Who first ran the organization.
• C. When the organization changed its name.
• D. What divisions make up the current CDC.

Correct answer: D

Rationale: The passage does not provide specific details about the divisions that currently make up the CDC. Instead, it focuses on the organization's historical context, original goals, and overall mission. Thus, D is correct as it identifies information not covered 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.
