Correct Answer: B

Rationale: The correct answer is B: 'In the rose garden out back.' This is an incomplete sentence because it lacks a subject and a verb. A complete sentence requires both a subject (who or what the sentence is about) and a verb (action or state of being). Choices A, C, and D are complete sentences as they have the necessary components to form a grammatically correct sentence. 'Watch out' has an implied subject (you) and verb (watch), 'I guess that's true' has the subject 'I' and the verb 'guess', and 'It would take about three weeks' has the subject 'It' and the verb phrase 'would take.'

Correct Answer: A

Rationale: The correct use of quotation marks in choice A is to enclose the title of a book, 'Where the Red Fern Grows,' indicating that it is a specific title that should be distinguished from the rest of the sentence. Choice B incorrectly uses quotation marks for movie titles, which should be italicized or underlined. Choice C correctly uses quotation marks for the title of a poem. Choice D has an extra space before the opening quotation mark, which is incorrect.

Correct Answer: C

Rationale: A compound sentence is made up of two independent clauses connected by a coordinating conjunction (such as 'and,' 'but,' 'so,' etc.) or a semicolon. In this case, 'The baby was sick' and 'I decided to stay home from work' are two independent clauses connected by the coordinating conjunction 'so.' Choice A is a simple sentence with one independent clause. Choice B is a complex sentence with an independent clause 'Marissa last saw Elena' and a dependent clause 'and talked to her this morning.' Choice D is also a simple sentence with one independent clause.

Correct Answer: A

Rationale: The correct answer is B: 'John threw the ball.' Active voice sentences have the subject performing the action, which is the case in this sentence where 'John' is the subject performing the action 'threw.' Choices A, C, and D are in passive voice where the subject receives the action rather than performing it.

Correct Answer: A

Rationale: The correct answer is 'Slang.' Slang refers to informal words or phrases that are specific to a particular group of people, such as young people or a specific culture. In this scenario, the teacher is hearing non-standard words and expressions used by students, which aligns with the definition of slang. Jargon typically refers to specialized terminology used within a specific profession or group. Dialect refers to a particular form of a language that is specific to a region or social group. Vernacular refers to the everyday language spoken by people in a particular region or country.
