Which of the following describes a visual tool that a writer uses to diagram ideas around a central concept?

Correct Answer: D

Rationale: A mind map is a visual tool commonly used by writers to diagram ideas around a central concept. It helps in brainstorming and organizing thoughts by visually representing the relationships between different ideas. Choice A, a bar graph, is a graphical representation of data typically used to compare quantities. Choice B, a citation, is a reference to a source used in writing to give credit. Choice C, revision, refers to the act of reviewing, editing, and improving written work.

Correct Answer: B

Rationale: The correct answer is 'After I finish my homework.' This is a dependent clause because it cannot stand alone as a complete sentence. It relies on the rest of the sentence for context and meaning. Choice A, 'Over the course of the day,' is a prepositional phrase, not a dependent clause. Choice C, 'I can't use my mother's car,' is an independent clause as it can function as a complete sentence on its own. Choice D, 'Through the tunnel,' is also a prepositional phrase and not a dependent clause.

Correct Answer: A

Rationale: Choice A is the correct answer as it presents a correctly punctuated compound sentence. It consists of two independent clauses separated by a comma and the coordinating conjunction 'and.' This punctuation accurately connects the two related ideas. Choice B is incorrect because it lacks a comma before the coordinating conjunction 'and,' making it a run-on sentence. Choice C is incorrect due to the use of a semicolon before the coordinating conjunction 'but,' which is unnecessary in this context. Choice D is incorrect as it lacks a comma before the coordinating conjunction 'but,' resulting in a comma splice error.

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: 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.
