In which sentence does the underlined noun clause contain an introductory word that has no function within the clause?

Answer 1

A noun clause is a dependent clause acting as a noun. In this case, the noun clause begins with "that". The introductory phrase are dependent clauses. It relies on the subject and verb in the main clause because it doesn't have its own subject and verb.
