Answer 1

Answer:

Defining relative clauses

We use defining relative clauses to give essential information about someone or something – information that we need in order to understand what or who is being referred to. A defining relative clause usually comes immediately after the noun it describes.

We usually use a relative pronoun (e.g. who, that, which, whose and whom) to introduce a defining relative clause (In the examples, the relative clause is in bold, and the person or thing being referred to is underlined.):

Non-defining relative clauses

We use non-defining relative clauses to give extra information about the person or thing. It is not necessary information. We don’t need it to understand who or what is being referred to.

We always use a relative pronoun (who, which, whose or whom) to introduce a non-defining relative clause (In the examples, the relative clause is in bold, and the person or thing being referred to is underlined.)

Answer 2

Answer:

Explanation: Non-defining clauses still add extra information, but not in the same way. While they tell you something additional, they're not necessary to the meaning of the sentence, but just add an extra non-essential dimension. ... The only difference is that you cannot use “that” with a non-defining clause, unlike defining clauses.
