ATI TEAS English and Language Usage

Correct Answer: A

Rationale: The correct answer is A because it is a correctly punctuated compound sentence. A compound sentence consists of two independent clauses joined by a coordinating conjunction (such as "and," "but," "or"). In choice A, "The moonlight glowed white on the roof next door" and "the sky was a gentle summer blue" are two independent clauses joined by the coordinating conjunction "and." This creates a grammatically correct compound sentence. Choices B, C, and D do not meet the criteria for a compound sentence as they either lack a coordinating conjunction (B), have a dependent clause (C), or use a comma splice (D), making them incorrect.

Correct Answer: C

Rationale: The correct answer is C. This option effectively combines the two sentences by using the conjunction "but" to show a contrast between Laura being on her way to a concert and being stuck in traffic. This helps convey the cause-and-effect relationship clearly. A is incorrect because it repeats the phrase "the concert" unnecessarily. B is incorrect as it separates the two ideas into two disjointed sentences. D is incorrect as it places the reason for missing the concert before the main action, which can cause confusion. In summary, C is the correct choice as it effectively combines the two sentences using the appropriate conjunction to show the relationship between the events.

Correct Answer: B

Rationale: The correct answer is B: To state the main idea of the essay. A thesis statement is a concise summary of the main point or claim of an essay, providing direction to the reader about what to expect. It guides the content and structure of the essay, helping the reader understand the purpose and focus. Summarizing the essay (choice A) is done in the conclusion, not the thesis. Asking a question (choice C) is not the main purpose of a thesis; it's more common in an introduction or body paragraphs. Providing evidence (choice D) is not the main purpose of a thesis; evidence is used to support the main idea stated in the thesis.

Correct Answer: B

Rationale: The correct answer is B: "who." In the sentence, "Mrs. Sato, who lives down the street, is 99 years old," the relative pronoun "who" introduces a relative clause providing essential information about Mrs. Sato. The relative pronoun "who" is used to refer to a person and is the appropriate choice in this context. A: "She" is a subjective pronoun and cannot be used to introduce a relative clause providing additional information about Mrs. Sato. C: "Which" is used to refer to things, not people, so it is not suitable in this context. D: "Whom" is an object pronoun and is not used to introduce relative clauses, so it is not the correct choice. Summary: The correct choice is "who" because it is a relative pronoun that refers to a person and is used to introduce essential information about Mrs. Sato in the sentence. The other choices (A, C,

Correct Answer: A

Rationale: The correct order for the sentence 'yesterday she went to the store' is A: She went to the store yesterday. This order follows the standard English sentence structure of subject-verb-object. 'She' is the subject, 'went' is the verb, and 'to the store yesterday' is the object and time frame. In this order, the sentence is clear and easy to understand. B: Incorrect - The prepositional phrase 'to the store' should come after the verb 'went'. C: Incorrect - The adverb 'yesterday' should come before the subject 'she' for proper chronological order. D: Incorrect - Adverb 'yesterday' should not come between the subject and the verb.
