Correct Answer:
D. Declarative
The sentence 'We took a test yesterday' is a declarative sentence.
- A declarative sentence makes a statement or expresses a fact or opinion, and it typically ends with a period. This sentence clearly states a fact about an event.
- A simple sentence refers to its grammatical structure (one independent clause), which this sentence is, but 'declarative' describes its function or purpose.
- A compound sentence contains two or more independent clauses joined by a conjunction or semicolon, which is not the case here.
- An imperative sentence gives a command or makes a request (e.g., 'Take the test!').
Therefore, 'Declarative' is the most accurate classification based on the sentence's function.
