Grammar for HESI A2 Questions
Question 1 of 5
Select the word or phrase that makes the following sentence grammatically correct. Two students ___________ the machine while the third oversaw their work.
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.
Question 2 of 5
Select the phrase in the following sentence that is not used correctly. Having completed the coursework that was required, Jorge now prepares for exam week.
Correct Answer: A
Rationale: The phrase 'Having completed' is not used correctly in the sentence. The correct form should be 'Having completed' to show that the action of completing the coursework has already been done. The use of 'complete' is incorrect as it should be 'completed' to maintain the correct verb form in the past participle.
Choice B, 'was required,' is used correctly as it is in the passive voice and fits the sentence structure.
Choice C, 'now prepares,' is also correct as it shows the current action of Jorge preparing for exam week.
Choice D, 'prepared for,' is not the phrase in question and is used correctly in the sentence to indicate the action Jorge took in the past to get ready for exam week.
Question 3 of 5
Select the phrase or clause that is misplaced in the following sentence. With torn pages, I returned the book I'd just bought to the store.
Correct Answer: A
Rationale: The phrase 'With torn pages' is misplaced in the sentence because it disrupts the flow of the sentence. Placing it at the beginning creates an awkward structure. It would be clearer to present the main action first before adding the detail about the torn pages. In this case, rearranging the sentence to 'I returned the book I'd just bought to the store with torn pages' would improve the sentence's coherence and readability.
Choices B, C, and D are not misplaced in the sentence as they follow a logical order of action and description.
Question 4 of 5
Select the word that makes the following sentence grammatically correct: The centrifuge cannot run by ___________; it requires constant attention.
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.
Question 5 of 5
Which of the following words or phrases fits best in the following sentence? If you ever ___________ at County Medical, you would know how grueling a shift there can be.
Correct Answer: A
Rationale: The word 'work' (option
A) is the most suitable choice for the sentence. The sentence is in the simple present tense and is discussing a general scenario or experience. The present simple tense is used to describe habits, routines, or general truths.
Therefore, the word 'work' best fits in this context to indicate a general experience at County Medical without specifying a particular timeframe.
Choices B, C, and D create incorrect tenses or imply specific past actions, which do not align with the intended meaning of the sentence.
