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: C

Rationale: In this sentence, the pronoun should refer to Luis, who borrowed the money. Since Luis is a male, the correct pronoun to use in this context is 'him.' Therefore, the correct answer is 'him.' Choices A, B, and D are incorrect as they do not match the gender of Luis or do not make sense in the context of 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: The word 'work' (option A) is the most suitable choice for the sentence. The sentence is in the simple present tense and is discussing a general scenario or experience. The present simple tense is used to describe habits, routines, or general truths. Therefore, the word 'work' best fits in this context to indicate a general experience at County Medical without specifying a particular timeframe. Choices B, C, and D create incorrect tenses or imply specific past actions, which do not align with the intended meaning of the sentence.

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.
