Correct Answer: B

Rationale: The correct plural form of 'chair' is 'chairs,' following the regular pluralization rule by adding 's.' Choices C and D, 'Chaires' and 'Chairies,' are incorrect because they do not follow the standard English pluralization rule. Choice A, 'Chair,' is the singular form and not the plural form of the word.

Correct Answer: A

Rationale: Choice A, 'I disagree with the argument about contract workers having greater freedom,' is the correct answer. This sentence rephrases the original statement in a more formal and respectful tone, which is suitable for formal writing. Choice B is too direct and lacks formality. Choice C does not address the argument directly and poses a question instead of providing a formal statement. Choice D is dismissive and does not offer a formal rewrite of the original sentence.

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: D

Rationale: Sentence D is a compound-complex sentence because it contains two independent clauses ('Even though the puppy was much smaller than his mother' and 'his eyes were dark brown and shiny just like hers') and one dependent clause ('and his ears were long and floppy, too'). Choices A, B, and C do not meet the criteria for a compound-complex sentence as they lack a combination of independent and dependent clauses.

Correct Answer: D

Rationale: The comma after 'delicious' is unnecessary as it separates the adjective 'delicious' from the noun 'stew'. In this case, 'delicious' is describing the type of stew, so the comma should be removed to maintain correct sentence structure. The other commas in the sentence are correctly used to separate items in a list and after introductory phrases, making them necessary for clarity and grammatical correctness.
