which of these is a complete sentence?

Known as the land of the midnight sun

To determine if a sentence is complete, we need to check if it has a subject and a predicate that expresses a complete thought.

Looking at the phrase "Known as the land of the midnight sun," we can identify that it has a subject, which is "Known," and a predicate, which is "as the land of the midnight sun." However, this phrase alone does not express a complete thought. It lacks a verb, and it seems to be functioning as a dependent clause rather than an independent sentence.

To transform this phrase into a complete sentence, we can add a verb and rephrase it. For example, we can say, "It is known as the land of the midnight sun." This sentence has a subject ("It") and a predicate ("is known as the land of the midnight sun") and expresses a complete thought.
