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: The correct answer is B: 'Let's eat, Grandma!' The comma is correctly used to separate the direct address 'Grandma' from the rest of the sentence. In choice A, there should be a comma after 'eat' to separate the direct address. Choice C is missing an apostrophe in 'Lets,' and there should be a comma after 'eat' to separate the direct address. Choice D incorrectly places a comma after 'Lets,' and there should be a comma after 'eat' to separate the direct address.

Correct Answer: C

Rationale: The correct answer is sentence C because it is a simple sentence containing only one independent clause. It expresses a complete thought with a subject 'The man in the blue pin-striped suit and checked tie' and a predicate 'looked somewhat out of place at the party.' Choices A, B, and D are not simple sentences. Choice A is a dependent clause as it does not express a complete thought on its own. Choice B is a prepositional phrase and does not form a complete sentence. Choice D is a complex sentence with a dependent clause ('because of his checked tie') along with the independent clause.

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: D

Rationale: The correct answer is D. This sentence uses the second person point of view by directly addressing the reader or listener with the phrase 'Be sure to.' It is instructing or advising someone on what action to take, making it a clear example of second person point of view. Choices A, B, and C all use first person (I) or third person (she, Pluto), which do not involve direct interaction with the reader or listener, unlike the second person point of view present in choice D.
