Correct Answer: C

Rationale: The correct answer is C: 'All-powerful'. 'Omnipotent' means having unlimited power or authority. Choice A, 'Well-worn', does not relate to the definition of omnipotent. Choice B, 'Overreaching', implies extending beyond proper limits but does not capture the essence of unlimited power. Choice D, 'Angry', does not align with the meaning of omnipotent.

Correct Answer: C

Rationale: The correct answer is C. 'Raze' is a homophone of 'raise,' which means to destroy completely. The other choices do not contain homophones. Choice A talks about a young woman walking on a canal path, choice B discusses water heating up and expanding, and choice D mentions a previous tenant who was a chemistry teacher, none of which involve homophones. Therefore, choice C is the only sentence that contains a homophone, making it the correct answer.

Correct Answer: A

Rationale: The correct answer is 'Slang.' Slang refers to informal words or phrases that are specific to a particular group of people, such as young people or a specific culture. In this scenario, the teacher is hearing non-standard words and expressions used by students, which aligns with the definition of slang. Jargon typically refers to specialized terminology used within a specific profession or group. Dialect refers to a particular form of a language that is specific to a region or social group. Vernacular refers to the everyday language spoken by people in a particular region or country.

Correct Answer: B

Rationale: The adjectives in the sentence are 'excellent,' 'walking,' 'rich,' and 'brotherly.' Adjectives are words that modify or describe nouns, and in this case, these words provide additional information about the walking tours and the history of Philadelphia. Choices A, C, and D do not contain adjectives. Choice A consists of nouns, Choice C includes verbs, and Choice D contains prepositions, none of which are adjectives as they do not describe or modify nouns.

Correct Answer: B

Rationale: Option B is the correct answer because it correctly places the period inside the closing quotation mark, following the closing punctuation of the sentence. This is the standard punctuation rule for quotations in American English. Choice A is incorrect as it has an extra period outside the closing quotation mark. Choice C is incorrect as the period should come after the closing quotation mark. Choice D is incorrect as it lacks the initial space before the quotation, not adhering to proper punctuation rules.
