ATI TEAS English and Language Usage

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: 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: 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: C

Rationale: The correct answer is C: Scientific journal article. This sentence suggests a research finding related to a potential therapy for a medical condition (OSAS). Scientific journal articles present research findings, evidence-based conclusions, and discuss the need for further clinical trials. They are written by experts in the field, provide detailed methodology, results, and conclusions. Incorrect choices: A: Motivational speech - Motivational speeches are meant to inspire or encourage, not present scientific evidence or research findings. B: Business memo - Business memos are used for internal communication within organizations and typically do not discuss scientific research or clinical trials. D: Personal blog - Personal blogs are informal platforms for personal opinions, experiences, or reflections, not for presenting scientific research or clinical trial information.

Correct Answer: D

Rationale: The correct answer is D, "thought." In this sentence, the verb should be in the past tense to indicate that the thinking happened before the decision. "Think" is present tense, "thank" is incorrect in this context, and "thinked" is not a valid past tense form. "Thought" is the correct past tense form of "think," making it the appropriate choice for this sentence.
