1. When ice melts, it undergoes a...

• A. Chemical change
• B. Physical change
• C. Nuclear change
• D. Radioactive decay

Correct answer: B

Rationale: When ice melts, it undergoes a physical change, transitioning from a solid state to a liquid state. This change does not involve altering the chemical composition of the ice, making it a physical change rather than a chemical change, nuclear change, or radioactive decay. Choice A, 'Chemical change,' is incorrect because a chemical change involves a rearrangement of atoms resulting in new substances. Choice C, 'Nuclear change,' is incorrect as it refers to changes in the nucleus of an atom, not the phase transition of ice. Choice D, 'Radioactive decay,' is incorrect as it involves the spontaneous disintegration of an unstable atomic nucleus, which is not the process occurring when ice melts.

2. Which of the following sources would be the best to understand the suspense genre better?

• A. A public library's digital catalog
• B. The online reviews of the genre
• C. A New York Times bestseller list
• D. An encyclopedia entry about the suspense genre

Correct answer: D

Rationale: The correct answer is D, an encyclopedia entry about the suspense genre. This choice would be the best source to understand the suspense genre better as it provides a comprehensive and detailed overview of the genre's history, characteristics, and key elements. Option A, a public library's digital catalog, may list suspense novels available but does not offer in-depth information about the genre itself. Option B, online reviews of the genre, are subjective opinions and may not provide a holistic view of the genre. Option C, a New York Times bestseller list, showcases popular titles but doesn't delve into the specifics of the suspense genre.

3. Which of the following is a unit of work and energy?

• A. Pascal (Pa)
• B. Kilowatt-hour (kWh)
• C. Coulomb (C)
• D. Tesla (T)

Correct answer: B

Rationale: The correct answer is 'B: Kilowatt-hour (kWh).' The kilowatt-hour is a unit commonly used to measure electricity consumption, representing energy usage over time. A Pascal (Pa) is a unit of pressure, Coulomb (C) is a unit of electric charge, and Tesla (T) is a unit of magnetic flux density. Therefore, the kilowatt-hour is the appropriate unit for measuring work and energy in this context.

4. What is the scientific name for the tear gland?

• A. Lachrymal gland
• B. Lacrimal sac
• C. Lacrimal duct
• D. Lacrimal papilla

Correct answer: A

Rationale: The correct answer is A: Lachrymal gland. The lachrymal gland, also known as the tear gland, is the almond-shaped gland located above each eye, responsible for producing tears. Tears are a complex mixture of water, electrolytes, proteins, and other substances that help lubricate and protect the eyes from dryness and irritation. Choice B, Lacrimal sac, is incorrect as it refers to a structure that collects tears from the eye. Choice C, Lacrimal duct, is incorrect as it is the tube that carries tears from the lacrimal sac to the nasal cavity. Choice D, Lacrimal papilla, is incorrect as it is a small elevation at the inner corner of the eye where tears drain into the puncta.

5. Which of the following describes a visual tool that a writer uses to diagram ideas around a central concept?

• A. Bar graph
• B. Citation
• C. Revision
• D. Mind map

Correct answer: D

Rationale: A mind map is a visual tool commonly used by writers to diagram ideas around a central concept. It helps in brainstorming and organizing thoughts by visually representing the relationships between different ideas. Choice A, a bar graph, is a graphical representation of data typically used to compare quantities. Choice B, a citation, is a reference to a source used in writing to give credit. Choice C, revision, refers to the act of reviewing, editing, and improving written work.
