Which word is used incorrectly in the following sentence? Which criteria were used to draw a conclusion about their findings?

Correct Answer: C

Rationale: The word 'draw' is used incorrectly in the sentence. The correct word that needs to be used is 'criteria' instead of 'criterion' to maintain subject-verb agreement. The correct sentence should be: 'Which criteria were used to draw a conclusion about their findings?' 'Draw' should be 'were drawn' to match the plural subject 'criteria.' The other choices are correct in the sentence and do not contain any errors.

Correct Answer: B

Rationale: In this sentence, 'to throw' is the correct form to use after the verb 'started' to indicate the action that the children began doing. The infinitive form 'to throw' is needed after the verb 'started' to show the purpose or action that is about to happen. When an action follows another action that has already started, the infinitive form is typically used to express the purpose or intention behind the subsequent action, making 'to throw' the most appropriate choice. Choices A, C, and D are incorrect because 'throw' is not the correct form to follow 'started' as it needs an infinitive form, 'threw' is the past tense which is not suitable in this context, and 'threwing' is an incorrect form of the verb that does not exist in standard English.

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: 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.
