What is the primary purpose of a restrictive clause?

1. To provide extra information

2. To define or identify a specific noun

3. To describe the actions taken

4. To indicate future actions

The correct answer is: To define or identify a specific noun

The primary purpose of a restrictive clause is to define or identify a specific noun. Restrictive clauses are essential to the meaning of the sentence because they narrow down the reference of the noun they modify. For example, in the sentence "The book that I borrowed from Sarah is excellent," the clause "that I borrowed from Sarah" restricts the meaning of "the book" to a specific book, clarifying which book is being discussed. Without the restrictive clause, the listener may not understand which book is meant, emphasizing the importance of this type of clause in providing necessary context. The other options pertain to different aspects of sentence structure and meaning. Providing extra information, describing actions, or indicating future actions may involve non-restrictive or other types of clauses but do not capture the defining function of a restrictive clause.
