Correct Answer: C

Rationale: The word 'college' is used incorrectly in the sentence. The correct term to use in this context would be 'capital,' not 'college.' 'Capital' refers to the city that serves as the seat of government, while 'college' refers to an educational institution. The sentence should read: 'She is already an adjunct at a capital in Raleigh, the capital of North Carolina.' Choices A, B, and D are all used appropriately 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: C

Rationale: The word 'otherwise' is used to indicate that although the patients are resting comfortably, under different circumstances, bed checks should still be done every half hour. This maintains the correct logic and flow of the sentence, making it grammatically correct. Choice A, 'despite,' would imply a contrasting situation that is not the intended meaning in this context. Choice B, 'however,' also implies a contrast rather than the intended conditional relationship. Choice D, 'afterward,' indicates a time sequence that does not fit the context of the sentence.

Correct Answer: A

Rationale: The word 'lose' in the sentence is not used correctly. The correct word should be 'lose,' which means to be deprived of or to fail to maintain possession of something. 'Loose' means not tight or free from restraint. In this context, 'lose' is the appropriate term to convey the idea of not maintaining patience or morale.

Correct Answer: B

Rationale: The correct phrase to use with 'surprised' in this sentence is 'to learn.' In this context, 'to learn' functions as an infinitive to indicate the purpose or reason for the surprise. 'Learning' (Choice A) is incorrect as it doesn't serve as an infinitive in this sentence. 'Of learning' (Choice C) is incorrect as it doesn't provide the correct structure needed in the sentence. 'Have learned' (Choice D) is incorrect because the verb tense does not match the context of the sentence.
