Correct Answer: C

Rationale: The word 'your' is used incorrectly in the sentence. The word 'your' is the possessive form that shows ownership, while 'you're' is a contraction of 'you are.' In this context, 'your' should be used to indicate that the packet belongs to the person. The correct sentence should be 'Follow the instructions you received in your packet.' The other choices ('Follow,' 'instructions,' and 'packet') are all used appropriately in the sentence and do not need any corrections.

Correct Answer: B

Rationale: The correct form to use in this sentence is the present participle 'taking.' The sentence should read, 'Before taking this medicine, consume a modest meal.' It is important to use the present participle form when talking about an action that occurs before another action. Choice A 'having taken' is incorrect as it suggests a completed action before consuming a meal. Choice C 'took' is in the past tense, not suitable for indicating an action that should happen before another. Choice D 'will take' is in the future tense, which does not fit the context of the sentence.

Correct Answer: B

Rationale: In this sentence, the subject 'board of education' is singular, so the verb should also be singular to match. 'Plans' is the correct form of the verb to use with a singular subject. The correct sentence should be: 'The board of education plans to hold a special meeting.' Choices A, C, and D are incorrect because they do not agree in number with the singular subject 'board of education.' 'Plan' is plural, 'planning' is a gerund form, and 'do plan' is not the correct verb form for the subject-verb agreement in this sentence.

Correct Answer: C

Rationale: In the context of the sentence, the word 'wound' is not used correctly. It should be 'wove' instead of 'wound.' The correct word usage should be: 'The staunch hikers took a torturous downhill path that wove through thick vegetation.' 'Wound' is the past tense of 'wind,' while 'wove' is the past tense of 'weave,' which is the appropriate verb to describe a path navigating through vegetation. Choice A, 'staunch,' Choice B, 'torturous,' and Choice D, 'vegetation,' are all used appropriately in the sentence and do not contain any errors.

Correct Answer: A

Rationale: The word 'incredible' is used incorrectly in the sentence. The correct form in this context should be 'incredibly' to modify the adjective 'complex.' Therefore, the corrected sentence is, 'The design was incredibly complex, with multicolored, repeating patterns.' The other choices (B, C, D) are used appropriately in the sentence and do not need any corrections.
