I think they have a right for artistic creation because they have their own speach
When writing a sentence, you will have a main idea, and you may also have a subordinate idea, a clause that has less importance than the main idea. Subordinate ideas, sometimes called a subordinate clause or a dependent clause, can help you prove or establish the importance of the main idea in your sentence. Knowing how to identify a subordinate idea will help you strengthen your writing skills.
I think the bolded words would be "whom Mr. Stein chose". The clause whom Mr. Stein chose is an example of an adjective because the clause describes the word student. Student is the subject of the sentence and is a noun. An adjective describes a noun or another subject. an adverb describes a verb or another adverb.
