ATI TEAS English Practice Test

Correct Answer: B

Rationale: The correct answer is B because it contains a dependent clause "after it ate." A dependent clause cannot stand alone as a complete sentence and relies on an independent clause to form a complete thought. In this case, "after it ate" does not express a complete idea on its own and depends on the independent clause "The cat sat on the mat" to make sense. Choices A, C, and D do not contain dependent clauses. Choice A is a simple sentence with no dependent clause. Choice C is a simple future tense sentence without a dependent clause. Choice D is a present continuous sentence without a dependent clause. Therefore, the correct answer is B as it clearly demonstrates the presence of a dependent clause within the sentence structure.

Correct Answer: B

Rationale: The correct answer is B because it maintains subject-verb agreement throughout the sentence. "The lead scientist is" matches the singular subject "The lead scientist," and "she is" matches the singular pronoun "she." In contrast, A uses "all scientists" with the singular verb "does," which is incorrect. Choice C has a subject-verb disagreement with "she is" and "does the research." Choice D also has a subject-verb disagreement with "every scientist" and "does the research." Therefore, B is the correct choice as it maintains consistency in subject-verb agreement.

Correct Answer: A

Rationale: The correct answer is A because the comma after the word 'think' is used incorrectly. Commas are typically used to separate items in a list, join independent clauses with a conjunction, or set off non-essential information. In this case, the comma after 'think' does not serve any of these purposes and creates a comma splice. The semicolon after 'do' is correct as it separates two closely related independent clauses. The period at the end of the sentence is also correct to indicate the end of a complete thought. The comma after 'and yet' is correctly used to separate introductory elements from the main clause.

Correct Answer: A

Rationale: The correct answer is A: ironic. Irony is when words convey a meaning that is opposite to their literal interpretation. In this case, the text's tone is ironic because it conveys a different meaning than what is explicitly stated. Earnest (B) means sincere and truthful, which is the opposite of the intended meaning in this context. Confused (C) implies a lack of clarity or understanding, not intentional contradiction. Unambiguous (D) means clear and straightforward, which is the opposite of the intended deceptive tone.

Correct Answer: A

Rationale: The correct answer is A: Who's. The contraction "Who's" is short for "who is" or "who has," making it appropriate in this context. It indicates possession or existence, clarifying the sentence's meaning. Choice B (Whos) is incorrect as it lacks the apostrophe needed in contractions. Choice C (Who'll) means "who will," which doesn't convey the intended meaning. Choice D (Who) is a pronoun and doesn't serve the purpose of indicating possession or existence required in the sentence. Therefore, A is the correct choice for maintaining clarity and grammatical correctness.
