Question

Read the sentence below and answer the question that follows.

Answer 1

The answer to your question would be that the clause underlined is a noun clause.  A noun clause, also known as nominal clause, is a group of words acting together as a noun. In addition to this, these clauses are always dependent clauses since they do not form a complete sentence and therefore cannot stand on their own as a complete thought.  Just as nouns, they can function as subject and object of a verb, subject complement, object of a preposition, and adjective complement.  

Coach William's intent is [that all players will have a chance to hit the field]

In this case, the nominal clause has been introduced by the complementizer "that" and it functions as a subject complement. A subject complement modifies, describes, or completes the subject of a clause. You can see this by asking the following question: What was Coach William's intent? Answer: that all the players will have a chance to hit the field.

Answer 2

I believe the answer is Adjective Clause because some signal words that give away that it could be an Adjective Clause is THAT, Which, Who, Whom, and Whose. And the word "That" is part of the underlined section, correct?
