HESI A2 Grammar Practice Exam
1. Which word is used incorrectly in the following sentence? The boys leapt up happy to assist their favorite teacher.
- A. leapt
- B. happy
- C. assist
- D. their
Correct answer: D
Rationale: The word 'their' is used incorrectly in the sentence. The correct word should be 'they're,' which is a contraction for 'they are.' The sentence should say: The boys leapt up, happy to assist their favorite teacher. Choice A, 'leapt,' is correctly used as the past tense of 'leap.' Choice B, 'happy,' is also correctly used as an adjective to describe the boys' emotional state. Choice C, 'assist,' is appropriately used as a verb to show the boys' willingness to help.
2. Select the word or phrase that makes the following sentence grammatically correct. Two students ___________ the machine while the third oversaw their work.
- A. operate
- B. operating
- C. were operating
- D. has been operating
Correct answer: A
Rationale: The word 'operate' is the correct choice as it agrees with the verb tense used in the sentence. In this case, the sentence requires the simple past tense. The correct form should be 'Two students operate the machine while the third oversaw their work.' Choices B, C, and D are incorrect because they do not match the required verb tense for the sentence. 'Operating' (choice B) is a present participle, 'were operating' (choice C) is past continuous, and 'has been operating' (choice D) is present perfect continuous, none of which fit the context of the sentence.
3. Select the phrase or clause that is misplaced in the following sentence: At a presentation, he informed us about the dangers of drugs and alcohol in the auditorium.
- A. At a presentation
- B. about the dangers
- C. of drugs and alcohol
- D. in the auditorium
Correct answer: D
Rationale: The phrase 'in the auditorium' is misplaced in the sentence because it suggests that the dangers of drugs and alcohol were in the auditorium, which is not the intended meaning. It would make more sense for this phrase to come immediately after 'he informed us' to indicate where the presentation took place. Choices A, B, and C are all correctly placed within the sentence, providing necessary information about the context and topic of the presentation.
4. Select the word that makes the following sentence grammatically correct. The girls have apparently ___________ curfew at least twice this week.
- A. broke
- B. break
- C. breaking
- D. broken
Correct answer: D
Rationale: The correct answer is 'D: broken.' In this sentence, the word 'broken' is the past participle form of the verb 'break' and is needed to complete the present perfect tense. The correct sentence should be 'The girls have apparently broken curfew at least twice this week.' Choices A, B, and C do not fit grammatically in the sentence because 'broke' is the simple past tense, 'break' is the base form, and 'breaking' is the present participle, whereas the sentence requires the past participle 'broken' for the present perfect tense.
5. What word is best to substitute for the underlined word in the following sentence? Roseanne was sent to the lab to collect Roseanne’s results.
- A. she
- B. their
- C. her
- D. hers
Correct answer: C
Rationale: The correct option to substitute for 'Roseanne’s' is 'her' to maintain correct pronoun-antecedent agreement. In this case, using 'her' makes the sentence grammatically correct and clear by referring back to Roseanne in a proper manner. Choice A, 'she,' is a subject pronoun and does not match the possessive form needed in the sentence. Choice B, 'their,' is plural and does not agree with the singular possessive 'Roseanne’s.' Choice D, 'hers,' is a possessive pronoun but cannot directly replace 'Roseanne’s' in this context; 'her' is the appropriate choice to indicate possession.
