Explanation:

• A non - restrictive clause is set off by commas. For example, in the sentence "My mother, who is a teacher, loves reading", the non - restrictive clause "who is a teacher" is separated by commas.
• A non - restrictive clause contains a subject and a verb. In the example above, "who" is the subject and "is" is the verb.
• A non - restrictive clause adds non - essential information. Removing it ("My mother loves reading") still leaves a complete and meaningful sentence.
