An imperative sentence is to a command as declarative to?

Here's why:

* Imperative sentences are used to give commands, make requests, or express instructions. They often start with a verb. (Example: "Close the door.")

* Declarative sentences are used to make statements or express facts. They are the most common type of sentence. (Example: "The sky is blue.")

So, just as an imperative sentence is specifically for giving a command, a declarative sentence is specifically for making a statement.
