HESI A2 Grammar Practice Test

Correct Answer: B

Rationale: The correct answer is B: Comma. A comma is needed before the coordinating conjunction "and" to separate the two independent clauses in the sentence. This comma is known as a serial comma or an Oxford comma. It clarifies the list of items and improves readability. Choosing A (Period) would create two separate sentences. Choosing C (Colon) is incorrect as colons are used for introducing lists or explanations. Choosing D (Hyphen) is incorrect as hyphens are used to connect words or parts of words.

Correct Answer: A

Rationale: The correct answer is A: with. In this sentence, "consult with" is the correct phrasal verb to use when seeking advice or input from peers. The preposition "with" is commonly used in this context to indicate collaboration or communication. The other options, such as "from," "by," and "in," do not convey the same meaning of actively seeking advice together with peers. "From" implies a one-way transfer, "by" suggests agency or method, and "in" does not fit the context of consulting peers. Selecting "with" ensures grammatical accuracy and clarity in the sentence.

Correct Answer: C

Rationale: The correct answer is C: study. In the sentence, "study" should be "studies" to match the singular subject Sidney. The verb should agree with the subject in number, so it should be "Sidney studies for the exam." A: "practices" is correct as it agrees with the subject Jack. B: "while" is used correctly as a conjunction to show simultaneous actions. D: "exam" is used correctly as the object of the preposition "for."

Correct Answer: B

Rationale: The correct answer is B: whom. In the sentence, "For whom was that email intended?" the word "whom" is used incorrectly. The correct form should be "who" as it is the subject of the verb "was intended." "Whom" is used for the object of a verb or preposition. The other choices (A, C, D) are used correctly in the sentence. "For" is a preposition, "that" is a demonstrative pronoun, and "intended" is the past participle of the verb "intend."Therefore, the correct choice is B.

Correct Answer: C

Rationale: The correct punctuation needed in the sentence is "C: Question mark." The sentence is a question as it is asking for confirmation about finishing reading the lab results. Therefore, it requires a question mark at the end to indicate this interrogative tone. A period (A) would make it a statement, not a question. A comma (B) would be incorrect as it does not fit the structure of a question. An exclamation mark (D) would be inappropriate as the sentence is not expressing excitement or surprise.
