1. Which of the following best describes the relationship among density, volume, and mass?

• A. As volume increases, density decreases.
• B. As volume decreases, density increases.
• C. An object's mass does not affect its density.
• D. As volume decreases, mass increases.

Correct answer: B

Rationale: The correct answer is B: 'As volume decreases, density increases.' This is because density is defined as mass divided by volume. When volume decreases and mass remains constant, the ratio of mass to volume increases, leading to higher density. Choice A is incorrect because as volume increases, density typically remains constant or increases due to the mass also increasing. Choice C is incorrect because an object's density is directly influenced by its mass. Choice D is incorrect as decreasing volume does not lead to an increase in mass.

2. Identify the noun clause in the sentence: 'My biggest fear is that I wouldn't live life to the fullest.'

• A. 'My biggest fear'
• B. 'that I wouldn't live life to the fullest'
• C. 'life'
• D. 'the fullest'

Correct answer: B

Rationale: The correct answer is B, 'that I wouldn't live life to the fullest.' This clause functions as the object of the verb 'is,' making it a noun clause. Noun clauses act as nouns within a sentence, often functioning as subjects, objects, or complements. Choice A ('My biggest fear') is a noun phrase, not a clause. Choice C ('life') and Choice D ('the fullest') are singular nouns and not clauses.

3. Robert scores three new clients every eight months. After how many months has he secured 24 new clients?

• A. 64
• B. 58
• C. 52
• D. 66

Correct answer: A

Rationale: To find out the number of months needed to secure 24 new clients, you can set up a proportion: 3 clients / 8 months = 24 clients / x months. Cross multiplying gives you 3x = 24 * 8. Solving for x: 3x = 192, x = 192 / 3, x = 64. Therefore, Robert will secure 24 new clients after 64 months. Choice A is correct. Choice B (58), Choice C (52), and Choice D (66) are incorrect as they do not align with the correct calculation based on the given proportion.

4. The passage describes recent hurricane seasons as the most expensive on record. Which of the following statements gives the implied reason for this increased expense?

• A. Hurricane Katrina was an extremely violent storm.
• B. Valuable buildings were destroyed in New Orleans.
• C. The Atlantic Basin is entering an active period.
• D. Destruction of barrier islands and coastal wetlands has left the mainland exposed.

Correct answer: D

Rationale: The destruction of barrier islands and coastal wetlands has left the mainland exposed, leading to increased damage and expenses from hurricanes. This implies a direct reason for the increased cost of recent hurricane seasons. The other choices do not directly address the reason for the increased expenses. Choice A talks about the intensity of Hurricane Katrina but does not explain the overall trend of increased expenses. Choice B mentions buildings being destroyed, which is a consequence rather than a reason for increased expenses. Choice C discusses an active period in the Atlantic Basin but does not connect it to the increased costs of hurricane seasons.

5. Which of the following is a strong acid?

• A. Acetic acid (CH₃COOH)
• B. Hydrochloric acid (HCl)
• C. Citric acid
• D. Carbonic acid (Hâ‚‚CO₃)

Correct answer: B

Rationale: Hydrochloric acid (HCl) is a strong acid because it completely ionizes in water to produce hydrogen ions, leading to a high concentration of H⁺ ions in solution. This characteristic makes it a strong acid. Acetic acid (CH₃COOH), citric acid, and carbonic acid (H₂CO₃) are weak acids as they only partially ionize in water, resulting in a lower concentration of H⁺ ions compared to strong acids. Therefore, hydrochloric acid is the correct choice as a strong acid.
