1. What conclusion can be drawn from the passage on the Amazon Rainforest?

A. The Amazon Rainforest is shrinking at a rapid pace.
B. The Amazon Rainforest is not affected by human activity.
C. The Amazon Rainforest will survive indefinitely.
D. The Amazon Rainforest has no significant impact on global warming.

Correct answer: A

Rationale: The correct conclusion that can be drawn from the passage on the Amazon Rainforest is that it is shrinking at a rapid pace. The passage explicitly mentions the rapid deforestation and shrinking of the Amazon Rainforest due to human activities like logging and burning. This conclusion is supported by the alarming statistics provided, such as 9,169 square miles of forest being cut down in Brazil in 2003, and an area of rainforest the size of a football field being burned down every minute. This rapid destruction poses a significant threat to the survival of the Amazon Rainforest and its biodiversity. Choice B is incorrect as the passage clearly states that human activities are causing harm to the rainforest. Choice C is incorrect because the passage highlights the current dangers and threats faced by the Amazon Rainforest, indicating that its survival is at risk. Choice D is also incorrect as the passage clearly explains the significant impact of deforestation in the Amazon Rainforest on global warming due to the release of carbon dioxide into the atmosphere.

2. 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.

3. A reader might infer from this passage that the organization ___________.

A. succeeded in eradicating malaria
B. has always been led by a medical doctor
C. no longer studies communicable diseases
D. changed its name to match its mission

Correct answer: D

Rationale: The passage never says whether or not the CDC succeeded in its original mission (choice A) or whether it continued to be led by doctors (choice B). Inferring either of those things would be a leap unsupported by the text. Choice C is countered by information in the final

4. What is the meaning of the word 'composed' in the first paragraph?

A. To consist of
B. To be uniquely discovered
C. To be set apart
D. To be surprised

Correct answer: A

Rationale: In the context provided, 'composed' means to consist of. The paragraph explains that a drop of water is composed of an oxygen atom and two hydrogen atoms. Therefore, the correct answer is A. Choice B, 'To be uniquely discovered,' is incorrect as it does not relate to the composition of a drop of water. Choice C, 'To be set apart,' and Choice D, 'To be surprised,' are also incorrect as they do not convey the meaning of 'composed' as it is used in this paragraph.

5. What conclusion can the reader draw after reading the passage about The Sleep Workout?

A. Getting uninterrupted sleep is more important than getting enough sleep.
B. Insufficient sleep may result in an increased risk for obesity.
C. Human growth hormone is not essential for muscle development.
D. Leptin is essential for building muscle.

Correct answer: B

Rationale: The correct answer is B because the passage highlights that insufficient sleep could lead to an increased risk of obesity. The passage emphasizes the importance of uninterrupted sleep in muscle development and mentions that inadequate sleep is linked to lowered levels of leptin, a hormone that controls appetite. This imbalance in leptin due to lack of sleep can lead to increased cravings for carbohydrates, contributing to obesity. Choice A is incorrect as the passage stresses the significance of both uninterrupted sleep and getting enough sleep for muscle growth. Choice C is incorrect because the passage clearly states that human growth hormone (HGH) is essential for muscle development. Choice D is incorrect as leptin is not essential for building muscle but is mentioned in the passage as a hormone related to controlling appetite and its link to inadequate sleep and obesity.
