Grammar for HESI A2
1. Select the word that makes the following sentence grammatically correct: The centrifuge cannot run by ___________; it requires constant attention.
- A. oneself
- B. itself
- C. herself
- D. themselves
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.
2. What word is best to substitute for the underlined words in the following sentence? Could Kendra manage to carry both Kendra’s books and yours?
- A. her
- B. his
- C. she's
- D. hers
Correct answer: D
Rationale: In the sentence, 'Could Kendra manage to carry both Kendra’s books and yours?', the possessive pronoun 'hers' is the best substitution for the underlined words. The use of 'hers' correctly indicates possession by Kendra, making it the most appropriate word choice to replace 'Kendra’s books'. Choice A, 'her', is incorrect as it refers to the possessive form of a singular female noun, not being possessive of 'Kendra'. Choice B, 'his', is incorrect as it is the possessive pronoun for a singular male noun, not suitable for replacing 'Kendra’s books'. Choice C, 'she's', is incorrect as it is a contraction for 'she is', which does not fit the possessive context needed in the sentence.
3. 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.
4. Select the phrase or clause that is misplaced in the following sentence: I noticed a number of workers from my car window who were repairing the road alongside the mall.
- A. of workers
- B. from my car window
- C. who were repairing the road
- D. alongside the mall
Correct answer: A
Rationale: The phrase 'of workers' is misplaced in the sentence because the preposition 'of' is unnecessary and disrupts the flow of the sentence. It creates redundancy as 'a number of workers' can be simplified to 'workers.' Removing this unnecessary prepositional phrase would make the sentence clearer and more concise. Choice B 'from my car window' is correctly placed as it provides context on where the observation was made. Choice C 'who were repairing the road' and Choice D 'alongside the mall' are essential parts of the sentence providing details about the workers' activity and location, respectively.
5. What word is best to fill in the blank in the following sentence? Jenny loaned Luis 50 dollars, and he repaid ___________ within the month.
- A. her
- B. she
- C. him
- D. its
Correct answer: C
Rationale: In this sentence, the pronoun should refer to Luis, who borrowed the money. Since Luis is a male, the correct pronoun to use in this context is 'him.' Therefore, the correct answer is 'him.' Choices A, B, and D are incorrect as they do not match the gender of Luis or do not make sense in the context of the sentence.
