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 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: B

Rationale: The word 'envelope' is used incorrectly in the sentence. The correct word should be 'folder,' as mentioned in the original sentence. An envelope is a flat paper container for a letter or documents, while a folder is a folded cover for papers or documents. 'Give,' 'whoever,' and 'replies' are all used appropriately in the sentence, so they are not the incorrect words.

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: B

Rationale: The word 'enthusiastic' is used incorrectly in the sentence. It should be 'enthusiastic' instead of 'enthusiastically' since it is describing Jeremiah's state of being, not an action he performed. Adverbs like 'enthusiastically' are used to modify verbs, not adjectives like 'enthusiastic'. The other choices ('seemed,' 'astonishing,' 'success') are all used appropriately in the sentence and do not need any correction.
