Which of the following sentences is an example of a complex sentence structure?

Correct Answer: B

Rationale: A complex sentence consists of one independent clause and at least one dependent clause. In sentence B, 'Because my tea was cold' is the dependent clause, indicating that it cannot stand alone as a complete sentence. Choices A, C, and D do not contain a dependent clause along with an independent clause, making them incorrect. Choice A is a compound sentence with two independent clauses joined by a coordinating conjunction. Choice C is a compound sentence with a series of independent clauses, but lacks a dependent clause. Choice D is a compound-complex sentence with two independent clauses and a dependent clause.

Correct Answer: A

Rationale: When a writer begins a new writing task, the first step is typically brainstorming. Brainstorming involves generating new ideas, concepts, and approaches before moving on to drafting. Option B, 'Final edit,' is incorrect as it refers to the last stage of the writing process, where the writer reviews and makes final adjustments to the completed draft. Option C, 'Draft,' is incorrect as it comes after brainstorming and involves putting the ideas into a structured form. Option D, 'Revision,' is also incorrect as it involves making changes and improvements to the draft after the initial writing phase.

Correct Answer: D

Rationale: The correct answer is 'Not enough.' The prefix 'hypo-' means 'under' or 'not enough,' as seen in the word 'hypokalemia,' which refers to low levels of potassium. 'Better' (choice A), 'Above' (choice B), and 'Too much' (choice C) are all incorrect because they do not convey the meaning of insufficient or low levels associated with hypokalemia.

Correct Answer: B

Rationale: Option B is the correct answer as it is a complex sentence with a dependent clause ('Before finishing her walk home') followed by an independent clause. In this sentence, 'Before finishing her walk home' acts as the dependent clause that sets the context for the main action, which is 'Raina stopped to watch the sunset.' Option A features two independent clauses connected by a comma and a coordinating conjunction, making it a compound sentence. Option C also has two independent clauses separated by a semicolon, which is incorrect punctuation for a complex sentence. Option D consists of two independent clauses connected by a comma and a coordinating conjunction, forming a compound sentence rather than a complex sentence.
