Select the word that makes the following sentence grammatically correct. The flock huddles against the wind that ruffles ___________ feathers.

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.

Correct Answer: A

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: D

Rationale: The correct phrase to use in this sentence is 'will listen and learn' because it indicates actions that will take place in the future. The verb 'will' is needed to show that these actions have not occurred yet but are planned for the upcoming months. Choices A, B, and C are incorrect because they do not convey the future tense required in the sentence. Choice A lacks the future tense, choice B is in the present continuous tense, and choice C is in the past perfect tense, which are all grammatically incorrect in this context.

Correct Answer: C

Rationale: The word 'complements' is not spelled correctly in the context of the sentence. The correct spelling should be 'complements,' which means 'enhances or goes well with.' 'Compliments' in this context would refer to expressions of praise or admiration. The other choices ('bride's,' 'stationery,' 'decor') are correctly spelled and fit the context of the sentence.

Correct Answer: B

Rationale: The correct answer is 'itself.' The sentence is referring to the centrifuge, which is an object, not a person. Therefore, the word 'itself' is used to indicate that the centrifuge cannot run on its own; it requires constant attention. Choices A, C, and D are incorrect because they refer to a person or people, which is not suitable in the context of the sentence.

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 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: The word 'deserve' should be used instead of 'deserves' to match the plural subject 'few'. The subject 'few' is plural, so the verb should also be plural. Therefore, the correct sentence should be 'but only a few deserve their degrees.' Choices A, B, and D are used correctly in the sentence and do not need any changes.

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.
