Correct Answer: B

Rationale: A verb is a word that expresses an action or state of being. In this sentence, 'chased' is the verb as it describes the action the dog is performing - chasing the fluffy squirrel. 'Around' is a preposition indicating location, 'squirrel' is a noun referring to the animal being chased, and 'the' is an article used to specify the squirrel. Therefore, the correct answer is 'chased.'

Correct Answer: C

Rationale: Option C uses formal language by employing more sophisticated vocabulary ('cinematic experience') and refraining from informal terms like 'awesome' and 'flick.' Choice A ('awesome') and Choice D ('flick') use informal language typically used in casual contexts, making them less formal. Choice B, while more formal than Choices A and D, is still less formal than Choice C due to its less sophisticated vocabulary and directness in expressing dissatisfaction compared to the refined language used in Choice C.

Correct Answer: C

Rationale: In this sentence, the word 'utter' best fits as it emphasizes the absolute and complete accuracy of the experiment. 'Utter' means total or complete, and in this context, it conveys a sense of total precision. Choices A, B, and D do not carry the same connotation of absolute precision. 'Extreme' and 'remarkable' may imply a high level of precision but not necessarily absolute or complete precision. 'Great' is a more general term that does not specifically emphasize the completeness of the precision required in conducting the experiment.

Correct Answer: C

Rationale: The underlined phrase 'with a mischievous grin' functions as an adverbial phrase in the sentence. It modifies the verb 'approached' by providing information on how he approached her, describing his manner. Adverbial phrases typically answer questions like 'how,' 'when,' 'where,' 'why,' or 'to what extent,' which this phrase does by indicating the manner in which he approached. Choices A, B, and D are incorrect. The phrase does not serve as a subject (A), direct object (B), or appositive phrase (D) in the sentence. Instead, it functions to provide additional information about the action of approaching, making it an adverbial phrase.

Correct Answer: C

Rationale: In the sentence 'The red car parked in the driveway,' the subject is 'car' because it is the noun that is performing the action of parking. The subject is typically the main noun that the rest of the sentence revolves around. 'Driveway' is part of the prepositional phrase 'in the driveway.' 'Red' is an adjective describing the car, and 'the' is an article providing information about the car but not the main noun carrying out the action.
