Which sentence is an example of a simple sentence?

• A. I wanted to eat, but I was not hungry
• B. Tina enjoys reading
• C. When the sun sets, it gets colder
• D. Although it was raining, we went for a walk

Answer: (B)

A simple sentence is defined as a sentence that contains a subject and a verb and expresses a complete thought. In the context of this question, the sentence "Tina enjoys reading" stands out as a simple sentence because it has a clear subject, "Tina," and a verb, "enjoys," together conveying a complete idea without the need for any additional clauses or conjunctions.

In comparison, the other sentences either contain additional elements like coordinating or subordinating conjunctions, which link different clauses, or they begin with dependent clauses that do not express a complete thought on their own. For instance, the first option has two independent clauses connected by "but," which makes it a compound sentence. The third option begins with "When the sun sets," which is a dependent clause and hence not a complete thought. Finally, the last option starts with "Although it was raining," indicating a dependent clause followed by an independent clause, making it a complex sentence. Thus, "Tina enjoys reading" is the only option that fits the definition of a simple sentence.
