What job is the noun clause doing in this sentence - We know whom students chose for cheerleader until Monday morning?

The noun clause "whom students chose for cheerleader" is functioning as the direct object of the verb "know".

Here's why:

* Noun Clause: It's a clause that acts like a noun. In this case, it's answering the question "What do we know?"

* Direct Object: It receives the action of the verb. The sentence is saying "We know *something*." That "something" is the noun clause.
