ATI TEAS English Practice Test

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: B

Rationale: The correct answer is B: have. In the sentence, 'students' is a plural noun, so it requires a plural verb. 'Have' is the correct present perfect tense form for plural subjects. 'Has' (A) is incorrect because it is the singular form. 'Is' (C) is incorrect as it is a singular verb, and 'was' (D) is incorrect as it is the past tense form. Therefore, 'have' best completes the sentence to match the plural subject 'students.'

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: C

Rationale: The correct answer is C because "shear" is a homophone error in the sentence. "Shear" means to cut or remove, which doesn't make sense in the context of the sentence. The correct word should be "sheer," which means absolute or pure. A: The homograph 'peeked' is correct as it means to look quickly or secretly. B: The homograph 'through' is correct as it indicates moving in one side and out of the other. D: The homophone 'scene' is correct as it refers to a part of a play or movie being performed.

Correct Answer: B

Rationale: The correct answer is B because it is a simple sentence that consists of a single independent clause expressing a complete thought ("Termites are very industrious insects"). It has a subject (termites) and a predicate (are very industrious insects). A is incorrect because it is a dependent clause and does not express a complete thought. C is incorrect because it is a compound sentence with two independent clauses connected by "and." D is incorrect because it is a complex sentence with a dependent clause ("Because termites are insects") and an independent clause.
