ATI TEAS English and Language Usage

Correct Answer: B

Rationale: The correct answer is B because the topic sentence introduces the main idea of the paragraph, which is that gingivitis is a mild form of gum disease caused by bacteria. It sets the stage for the subsequent details to explain and support this main idea. In contrast, choices A, C, and D provide supporting details or consequences of gingivitis, rather than introducing the main idea. Therefore, they cannot be the topic sentence as they do not establish the central theme of the paragraph.

Correct Answer: B

Rationale: The correct answer is B: Noun. 'Singing' functions as the subject of the sentence, which is a characteristic of a noun. Nouns can serve as subjects, objects, or complements in a sentence. In this sentence, 'Singing' is the subject performing the action of being the favorite activity. Incorrect choices: A: Verb - A verb is an action word that denotes an action or a state of being. 'Singing' is not describing an action but rather the subject of the sentence. C: Adjective - Adjectives modify nouns or pronouns, providing more information about them. 'Singing' is not describing another noun or pronoun here. D: Pronoun - Pronouns are words that replace nouns. 'Singing' does not replace a noun in this sentence; it is the main noun itself.

Correct Answer: C

Rationale: The correct answer is C because it correctly uses punctuation for a plural possessive noun. "Clients'" indicates that the complaints belong to multiple clients. The apostrophe comes after the "s" to show possession by a group. In contrast: - A uses an apostrophe before the "s," which is incorrect for a singular possessive noun. - B incorrectly places an apostrophe before each name, which is unnecessary when they jointly own the business. - D is incorrect as it shows possession by a single busy worker, but the sentence implies possession by multiple busy workers.

Correct Answer: A

Rationale: The prefix 'inter-' means "among" or "between." In this context, intergalactic means "between galaxies." The spaceship is designed to travel between different galaxies. Therefore, the correct answer is A. The other choices are incorrect because they do not convey the same meaning as the prefix 'inter-' in the given sentence. B: Below, C: Around, D: Above do not fit the context of the sentence, which specifically refers to traveling between galaxies.

Correct Answer: A

Rationale: The correct answer is A: Proofreading. In the last step of the writing process, proofreading is done to correct errors in grammar, punctuation, spelling, and formatting. This ensures the final piece is polished and error-free. Brainstorming is an early step to generate ideas, not part of the final step. Citing primary sources is part of the research process, not specifically the last step of writing. Identifying a thesis is typically done in the early stages of writing to establish the main argument. Proofreading is crucial in the final step to ensure clarity and coherence.
