1. What conclusion can a reader draw about the connection between sleep and young children?

• A. Lack of sleep causes children to fail in school.
• B. Inadequate rest raises the risk of behavioral and physical problems.
• C. Sleeping less than 10 hours a night is guaranteed to result in obesity.
• D. Eight hours of sleep each night meets the requirements of most children.

Correct answer: B

Rationale: The study outlined in the passage indicates that children who lack adequate sleep are at a higher risk for behavioral and physical issues, such as obesity and attention disorders. This conclusion is derived from the evidence provided in the passage, suggesting a direct link between sleep deprivation and negative outcomes, thus supporting option B..

2. 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.

3. What is the main idea of this passage?

• A. The water cycle consists of precipitation, evaporation, and condensation
• B. Water cycle components include only evaporation and condensation
• C. The water cycle includes precipitation, runoff, evaporation, and condensation
• D. The water cycle happens in the atmosphere only

Correct answer: A

Rationale: The correct answer is A: 'The water cycle consists of precipitation, evaporation, and condensation.' The passage explains the stages of the water cycle, which are precipitation (rain, snow, sleet, or hail), runoff, evaporation, and condensation. Choice B is incorrect because the water cycle involves more than just evaporation and condensation. Choice C is incorrect as it includes an additional element, runoff, not mentioned as a primary component of the water cycle in the passage. Choice D is incorrect as the water cycle involves processes both in the atmosphere and on the ground.

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 implied about the rainforest's role in global climate?

• A. The rainforest has little impact on the climate.
• B. The rainforest plays a crucial role in regulating the climate.
• C. The rainforest is mainly important for biodiversity.
• D. The rainforest's destruction has no global consequences.

Correct answer: B

Rationale: The rainforest plays a crucial role in regulating the global climate by absorbing carbon dioxide. The extract highlights the fact that trees take in carbon dioxide and give off oxygen. When trees are cut down, the amount of carbon dioxide increases, contributing to global warming. This emphasizes the significant impact of rainforests on the climate. Choice A is incorrect as the extract clearly states the importance of rainforests in absorbing carbon dioxide. Choice C, while true, is not directly related to the implied role of rainforests in regulating the climate. Choice D is also incorrect as the destruction of rainforests does have global consequences, such as contributing to global warming.
