Correct Answer: C

Rationale: Choice C, 'A multitude of clients' complaints filled the comment box,' is the correct answer. 'Clients'' is the plural possessive form to indicate that the complaints belong to the clients. In Choice A, 'baby's' is correctly punctuated to show the bibs belong to the baby. Choice B, 'Sarah's and Claire's business was thriving in its new location,' incorrectly uses an apostrophe before 'business,' making it possessive twice. Choice D, 'A busy worker's best tool is a good plan,' correctly shows possession of the best tool by the busy worker.

Correct Answer: B

Rationale: The topic sentence in a paragraph typically introduces the main idea or topic of the paragraph. In this case, choice B correctly serves as the topic sentence by clearly stating that gingivitis is a mild form of gum disease caused by bacteria that leads to inflammation of the gums. Choices A, C, and D provide additional information that supports or follows the main idea but do not present the overarching topic of the paragraph.

Correct Answer: B

Rationale: The main purpose of a thesis statement is to clearly state the main idea or argument of the essay. It serves as a roadmap for the reader, outlining the central point that the essay will address. Choice A, 'To summarize the essay,' is incorrect because while a thesis statement does provide a concise summary of the main point, its primary function is to present the main idea, not summarize the entire essay. Choice C, 'To ask a question,' is incorrect as a thesis statement is a declarative statement that asserts a position or argument rather than posing a question. Choice D, 'To provide evidence,' is incorrect because a thesis statement does not offer evidence but rather sets the direction and focus for the evidence that will be presented in the essay.

Correct Answer: A

Rationale: The correct answer is 'questionnaire.' A questionnaire is a set of questions used for gathering information. The incorrect choices B, C, and D have misspellings of the word 'questionnaire.' 'Questionaire,' 'questionnare,' and 'questionairre' are not correct spellings and may lead to confusion or misunderstanding. It is essential to use the correct spelling to ensure clear communication in healthcare settings.

Correct Answer: D

Rationale: 'Ridiculously' is an adverb in this sentence, modifying the adjective 'easy.' Adverbs typically modify adjectives, verbs, or other adverbs. In this case, 'ridiculously' is describing the adjective 'easy,' indicating the degree or manner of the adjective. Choices A, B, and C are incorrect. 'Ridiculously' is not a verb (choice A) as it is not expressing an action or state. It is not an interjection (choice B) since it is not an abrupt exclamation. Also, it is not an adjective (choice C) as it is not directly modifying a noun or pronoun.
