Correct Answer: A

Rationale: The phrase 'Having completed' is not used correctly in the sentence. The correct form should be 'Having completed' to show that the action of completing the coursework has already been done. The use of 'complete' is incorrect as it should be 'completed' to maintain the correct verb form in the past participle. Choice B, 'was required,' is used correctly as it is in the passive voice and fits the sentence structure. Choice C, 'now prepares,' is also correct as it shows the current action of Jorge preparing for exam week. Choice D, 'prepared for,' is not the phrase in question and is used correctly in the sentence to indicate the action Jorge took in the past to get ready for exam week.

Correct Answer: C

Rationale: In the given sentence, the word 'effect' is used incorrectly. In this context, the word 'affect' should be used instead of 'effect.' 'Affect' is a verb that means to influence or have an impact on something, while 'effect' is a noun that represents the result or outcome of an action. Therefore, to convey the intended meaning that her mentor's advice was bound to influence or impact her final decision, the correct word should be 'affect,' not 'effect.' The other options ('mentor's,' 'advice,' 'decision') are used appropriately in the sentence and do not contain any errors.

Correct Answer: C

Rationale: In the context of the sentence, the word 'then' is used incorrectly. The correct word that should be used is 'than,' which is used to make comparisons. The sentence should read, 'Nothing can be more delightful than a late-night swim in the reservoir.' The other choices 'Nothing,' 'delightful,' and 'reservoir' are spelled correctly and are contextually appropriate in the sentence.

Correct Answer: D

Rationale: In the sentence, 'Could Kendra manage to carry both Kendra's books and yours?', the possessive pronoun 'hers' is the best substitution for the underlined words. The use of 'hers' correctly indicates possession by Kendra, making it the most appropriate word choice to replace 'Kendra's books'. Choice A, 'her', is incorrect as it refers to the possessive form of a singular female noun, not being possessive of 'Kendra'. Choice B, 'his', is incorrect as it is the possessive pronoun for a singular male noun, not suitable for replacing 'Kendra's books'. Choice C, 'she's', is incorrect as it is a contraction for 'she is', which does not fit the possessive context needed in the sentence.

Correct Answer: A

Rationale: In this sentence, the word 'flock' is singular, so the pronoun that follows should also be singular. Therefore, the correct choice is 'its,' which refers back to the singular noun 'flock.' Choice B ('their') is incorrect because it is a plural pronoun and does not agree in number with the singular noun 'flock.' Choices C ('it's') and D ('they're') are both incorrect contractions that do not fit grammatically in this context.
