1. What type of text includes the author's purpose, major ideas, supporting details, visual aids, and vocabulary as key elements?

• A. Fictional texts
• B. Persuasive texts
• C. Narratives
• D. Informational texts

Correct answer: D

Rationale: The key elements mentioned (author's purpose, major ideas, etc.) are typically associated with informational texts. Informational texts aim to inform and educate the reader, making use of these elements to convey factual information. Fictional texts focus more on storytelling, character development, and plot, while persuasive texts aim to convince or persuade the audience. Narratives are stories that can be fictional or non-fictional, emphasizing a sequence of events rather than the specific elements mentioned in the question.

2. Which property describes a substance's resistance to flow?

• A. Density
• B. Viscosity
• C. Conductivity
• D. Reactivity

Correct answer: B

Rationale: Viscosity is the property that describes a substance's resistance to flow. A substance with high viscosity flows slowly, while a substance with low viscosity flows quickly. Density (A) is the measure of mass per unit volume; conductivity (C) is the ability of a material to conduct electricity or heat, and reactivity (D) refers to how readily a substance undergoes chemical reactions. Therefore, the correct answer is B, viscosity, as it directly relates to a substance's resistance to flow.

3. Which of the following sentences contains a colloquialism?

• A. The Centers for Disease Control and Prevention is pretty sure that the Zika virus is spread through mosquito bites.
• B. Travelers who are pregnant or considering pregnancy should consult a doctor.
• C. Some theories on the Zika virus are difficult to understand.
• D. In response, the U.S. has taken steps to prevent the spread of the Zika virus.

Correct answer: A

Rationale: The correct answer is A because the phrase 'pretty sure' is a colloquialism, making the sentence less formal. Choice B is incorrect as it is a formal recommendation. Choice C is incorrect as it contains no colloquial expressions. Choice D is incorrect as it is a straightforward statement without colloquial language.

4. Which part of the brain controls the coordination of muscle movements?

• A. Cerebrum
• B. Cerebellum
• C. Thalamus
• D. Medulla oblongata

Correct answer: B

Rationale: The cerebellum is the part of the brain responsible for controlling the coordination of muscle movements and helping to maintain balance. It receives information from the sensory systems, the spinal cord, and other parts of the brain to regulate voluntary movements. The cerebrum (choice A) is primarily responsible for higher brain functions such as thinking and decision-making, not muscle coordination. The thalamus (choice C) acts as a relay station for sensory information but is not directly involved in muscle coordination. The medulla oblongata (choice D) is responsible for regulating vital autonomic functions like breathing and heart rate, rather than muscle coordination.

5. What is the function of the rib cage in the human body?

• A. To protect the digestive organs
• B. To protect the lungs and heart
• C. To support movement
• D. To regulate body temperature

Correct answer: B

Rationale: The rib cage plays a crucial role in protecting vital organs, specifically the lungs and heart, from external injuries. Choice A is incorrect because the rib cage does not primarily protect the digestive organs. Choice C is incorrect as the primary function of the rib cage is not to support movement, but to protect internal organs. Choice D is incorrect as regulating body temperature is not a function typically associated with the rib cage.
