Correct Answer: A

Rationale: The correct word to use in this sentence is 'volunteered' as it indicates an action that Cathy did in the past. The sentence suggests that Cathy was engaging in volunteering at the hospital for the first time, so the past tense form 'volunteered' is the most appropriate choice. Choice B ('volunteering') is incorrect because it is the present participle form and does not fit the past tense context of the sentence. Choice C ('was volunteered') is passive voice and implies that someone else made Cathy volunteer, which is not the intended meaning. Choice D ('volunteer') is incorrect as it is the base form of the verb and does not match the past tense requirement of the sentence.

Correct Answer: D

Rationale: The correct form in this sentence is 'inputting,' as it is the gerund form of the verb 'input.' The gerund form is used to show that Kalinda spends part of her day engaging in the ongoing action of inputting data from the lab. Choice A ('inputs') is incorrect as it is the third-person singular form of the verb, which does not fit here. Choice B ('input') is incorrect as it is the base form of the verb and does not convey the ongoing action required in this context. Choice C ('having input') is incorrect as it suggests a completed action rather than an ongoing one.

Correct Answer: A

Rationale: The correct answer is 'A - spoke to the patient's parents.' In this sentence, the past tense 'spoke' should be used to match the past tense 'had,' indicating an action that already took place. Choices B, C, and D are incorrect because they use present or future tenses, which do not match the past tense 'had' in the sentence.

Correct Answer: D

Rationale: The word 'his' is the possessive form of the pronoun 'Mr. Menotti,' indicating that the belongings belong to him. Using 'her,' 'him,' or 'he' would not be grammatically correct in this context as they do not reflect the possession by Mr. Menotti. 'Her' would imply the belongings belong to his wife, 'him' is an objective pronoun, and 'he' is a subject pronoun, neither of which correctly shows possession.

Correct Answer: B

Rationale: The correct preposition to use in this sentence to indicate the position of the fountain in relation to the driveway and the main entrance is 'between.' 'Between' conveys that the fountain is positioned centrally or in the middle of the driveway and the main entrance, making it the most suitable phrase to complete the sentence correctly. The other options do not accurately describe the fountain's position between two distinct locations, making them grammatically incorrect choices for this sentence.
