1. What is the meaning of pernicious?

• A. Harmless
• B. Destructive
• C. Infectious
• D. Helpful

Correct answer: B

Rationale: The correct answer is B, 'Destructive.' Pernicious means causing great harm or damage. Choice A, 'Harmless,' is the opposite of pernicious. Choice C, 'Infectious,' refers to the ability of a disease to spread. Choice D, 'Helpful,' is also the opposite of pernicious and does not capture the negative connotation associated with the term.

2. Casey spent $80 on items where each item costs $4. How many items did Casey buy?

• A. 12
• B. 18
• C. 20
• D. 24

Correct answer: C

Rationale: To determine the number of items Casey bought for $80, we divide the total amount spent ($80) by the cost per item ($4). The calculation gives us 20, indicating that Casey bought 20 items in total to reach the $80 expenditure ($80 ÷ $4 = 20). Therefore, the correct answer is C, 20. Choices A (12), B (18), and D (24) are incorrect because they do not align with the correct division calculation based on the information provided.

3. What is the name of the phase change from liquid to gas?

• A. Condensation
• B. Sublimation
• C. Evaporation
• D. Melting

Correct answer: C

Rationale: The correct answer is 'Evaporation.' This phase change occurs when a liquid turns into a gas. During evaporation, molecules gain enough energy to break free from the liquid phase and enter the gas phase, without the need for the liquid to reach its boiling point. Choice A, 'Condensation,' is the opposite phase change where gas turns into a liquid. Choice B, 'Sublimation,' is the phase change from solid directly to gas, skipping the liquid phase. Choice D, 'Melting,' is the phase change from solid to liquid.

4. Which is an example of a gymnosperm?

• A. Red cedar
• B. Japanese cherry
• C. Flowering dogwood
• D. American chestnut

Correct answer: A

Rationale: Red cedar is the correct answer as it is an example of a gymnosperm. Gymnosperms are plants that produce seeds not enclosed within an ovary or fruit. In the case of red cedar, it belongs to the gymnosperm group and has naked seeds that are exposed on the surface of scales or leaves. Choices B, C, and D are angiosperms, not gymnosperms. Japanese cherry, flowering dogwood, and American chestnut are all examples of angiosperms, which are flowering plants with seeds enclosed within an ovary.

5. What does the word Quarantine mean?

• A. Isolation
• B. Confinement away from the general population
• C. Treatment
• D. Exposure

Correct answer: B

Rationale: The correct answer is B: 'Confinement away from the general population.' Quarantine is the practice of isolating individuals who may have been exposed to a contagious disease but are not yet ill. This isolation helps prevent the potential spread of the disease. Choice A, 'Isolation,' is partially correct but does not capture the specific aspect of separation from the general population. Choice C, 'Treatment,' is incorrect as quarantine does not involve providing medical care but rather focusing on preventing transmission. Choice D, 'Exposure,' is also incorrect as quarantine is about separating potentially exposed individuals, not intentionally exposing them.
