I think that what you are asking is which word is a subject complement in that sentence. What I think the answer to this question is the word third.
Answer and Explanation:
A meaningful drill suitable for teaching students what a substantive clause is would be a list with several sentences where some contain the substantive clause and others do not. In this case, students should identify the sentences that contained the substantive clauses and underline these clauses.
It is important to point out that the noun clause is the dependent clause that replaces the noun, which is the class of words that gives name to any element. An example of this noun clause can be seen in the sentence "She was frightened by the sight in front of her," where the term "the sight in front of her" replaces a noun and is therefore a noun clause.
In addition, it is important to remember that a meaningful drill is an exercise where the resolution depends on the understanding of the subject discussed.
