Identify the type of clause in the sentence: 'I ate, and he drank.'

Correct Answer: A

Rationale: The correct answer is 'A: Coordinate clause.' In the sentence 'I ate, and he drank,' 'I ate' and 'he drank' are coordinate clauses. They are both independent clauses that are joined by the coordinating conjunction 'and.' A coordinate clause is a type of independent clause that is equally important and balanced within a sentence. A dependent clause cannot stand alone as a complete sentence and relies on an independent clause. A subordinate clause is a type of dependent clause that functions within a sentence to provide additional information but does not express a complete thought. An independent clause, on the other hand, can stand alone as a complete sentence.

Correct Answer: B

Rationale: The correct answer is 'I will be unable to come to your party.' This sentence uses formal language by avoiding contractions and employing a more polished wording. Choice A, 'I can't come to your party,' contains a contraction ('can't'), which makes it less formal. Choice C, 'I won't be able to go to your party,' though polite, still uses a contraction ('won't') and is not as formal as the correct answer. Choice D, 'I can't go to your party,' also includes a contraction and is less formal compared to the most formal choice, which is option B.

Correct Answer: B

Rationale: The correct answer is writing a postcard (Choice B). A postcard is a casual form of communication, typically sent to friends or family, making it a suitable context for informal language. Using informal language in a seminar (Choice A) would be inappropriate as it is a formal setting where professional language is expected. Talking to your boss (Choice C) and participating in a professional conference (Choice D) also require formal language to maintain professionalism and respect for the workplace environment.

Correct Answer: D

Rationale: The correct answer is D: At a Parent-Teacher meeting. A Parent-Teacher meeting is a formal setting where professional communication is expected. Using formal language in this context shows respect and professionalism. Choices A, B, and C involve informal or casual situations where using formal language may not be necessary or appropriate. Texting a friend, attending a family reunion, or Skyping with grandparents are typically more informal interactions where a more relaxed communication style is acceptable.

Correct Answer: A

Rationale: The correct answer is 'tele,' which means far. This root word is commonly found in words like 'telephone' and 'television,' where 'tele' indicates a distance or far-reaching transmission. 'Trans' (choice B) means across or beyond, not specifically far. 'Post' (choice C) means after or later, and 'ante' (choice D) means before or prior, neither of which conveys the meaning of far.
