1. The area known as the Bermuda Triangle has become such a part of popular culture that it can be difficult to separate fact from fiction. Which of the following describes this type of writing?

• A. Narrative
• B. Persuasive
• C. Expository
• D. Technical

Correct answer: C

Rationale: Expository writing is used to explain or inform, as seen in the factual account of the Bermuda Triangle. The passage provides information to explain the phenomenon of the Bermuda Triangle, presenting facts and details without attempting to persuade or tell a story (narrative) or focusing on technical details. While the Bermuda Triangle has inspired many stories and theories, the passage aims to inform rather than persuade or delve into technical aspects.

2. What type of reaction is represented by the following equation: 2C₆H₁₄ + 19O₂ → 12CO + 14H₂O?

• A. Substitution reaction
• B. Acid-base reaction
• C. Enzyme reaction
• D. Combustion reaction

Correct answer: D

Rationale: The given chemical equation represents a combustion reaction. Combustion reactions involve the burning of a hydrocarbon (C₆H₁₄) in the presence of oxygen (O₂) to produce carbon monoxide (CO) and water (H₂O). Combustion reactions typically release heat and light energy. In this case, the reactants are a hydrocarbon and oxygen, resulting in the formation of carbon monoxide and water. Choices A, B, and C are incorrect because the reaction does not involve substitution, acid-base reactions, or enzyme catalysis. Combustion reactions are characterized by the rapid combination of a substance with oxygen, leading to the production of heat and light energy.

3. Which type of chemical reaction produces a salt?

• A. An oxidation reaction
• B. A neutralization reaction
• C. A synthesis reaction
• D. A decomposition reaction

Correct answer: B

Rationale: The correct answer is B, a neutralization reaction. In a neutralization reaction, an acid and a base react to produce a salt and water. This process involves the combination of H+ ions from the acid and OH- ions from the base to form water, while the remaining ions combine to form a salt. Therefore, a neutralization reaction is the specific type of chemical reaction that produces a salt. Choices A, C, and D are incorrect. An oxidation reaction involves the loss of electrons, a synthesis reaction involves the formation of a compound from simpler substances, and a decomposition reaction involves the breakdown of a compound into simpler substances. None of these reactions directly lead to the production of a salt, making them incorrect choices in this context.

4. What can one infer about the meaning of the word 'Juggernaut' from the author's use of it in the passage?

• A. It is an apparition that appears at daybreak.
• B. It scares children.
• C. It is associated with space travel.
• D. Mr. Utterson finds it soothing.

Correct answer: B

Rationale: The word 'Juggernaut' is used metaphorically in the passage to describe a powerful and destructive force, as seen when the child is trodden down and left screaming. This metaphorical usage aligns with choice B, 'It scares children,' as it conveys the idea of something imposing and frightening. Choices A, C, and D are incorrect as they do not capture the negative and forceful connotation associated with the term 'Juggernaut' in the passage. Therefore, the correct answer is B.

5. What is missing from the following sentence: 'He asked, When is the assignment due?'

• A. There should be quotation marks.
• B. There needs to be a semicolon after 'asked.'
• C. There should be a comma after 'assignment.'
• D. Nothing is missing.

Correct answer: A

Rationale: The correct answer is A. The sentence is missing quotation marks around 'When is the assignment due?'. Quotation marks are essential to indicate that the words enclosed are being directly quoted. Choice B is incorrect because a semicolon is not needed in this context. Choice C is incorrect as a comma is already present after 'He asked' to separate the introductory clause. Choice D is incorrect because the sentence does lack proper punctuation, which are the quotation marks.
