HESI A2 Grammar Practice Test
1. What word is best to substitute for the underlined words in the following sentence? Stu often regarded his roommates’ housekeeping as sloppy and careless.
- A. his
- B. hers
- C. them
- D. their
Correct answer: D
Rationale: The word 'their' is the best substitute for the underlined words in the sentence because it refers to Stu's roommates in a possessive form, indicating that the housekeeping belongs to them. 'His' (Choice A) refers to Stu, not the roommates. 'Hers' (Choice B) is incorrect as it refers to a female possessive form. 'Them' (Choice C) is a pronoun for a group of people but does not show possession, making it unsuitable in this context.
2. Which word is used incorrectly in the following sentence? Please give the folder to whoever replies to your page.
- A. give
- B. envelope
- C. whoever
- D. replies
Correct answer: B
Rationale: The word 'envelope' is used incorrectly in the sentence. The correct word should be 'folder,' as mentioned in the original sentence. An envelope is a flat paper container for a letter or documents, while a folder is a folded cover for papers or documents. 'Give,' 'whoever,' and 'replies' are all used appropriately in the sentence, so they are not the incorrect words.
3. Select the word that correctly completes the following sentence: 'The intern was surprised by the ____ of pain he was in after his first day of work.'
- A. amount
- B. frequency
- C. number
- D. amplitude
Correct answer: A
Rationale: The correct answer is 'amount.' In this context, 'amount' is used to describe the intensity or level of pain, which is an uncountable noun. 'Frequency' (B) refers to how often something occurs, 'number' (C) is used for countable objects, and 'amplitude' (D) is typically used in the context of sound or waves, not pain.
4. 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.
5. 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.
