Can someone help me with this?

Is this a simple sentence or a fragment?

We knew that we would lose the game and the opportunity of a state championship.

It is a complete sentence, but not a simple one.

It is a complex sentence We- subject, Knew verb, That we would lose----- noun clause - direct object.

To determine whether the given sentence is a simple sentence or a fragment, you can analyze the structure and components of the sentence.

In this case, the sentence "We knew that we would lose the game and the opportunity of a state championship" is a complete sentence. It contains a subject ("We") and a verb ("knew"), which makes it a sentence rather than a fragment.

Additionally, the sentence includes a dependent clause introduced by the conjunction "that" ("that we would lose the game and the opportunity of a state championship"). This clause functions as the direct object of the verb "knew." Therefore, the sentence is a complex sentence, as it contains both an independent clause ("We knew") and a dependent clause ("that we would lose the game and the opportunity of a state championship").
