Defining and non-defining relative clauses - Intermediate

Practice on the defining and non-defining relative clauses

A relative clause is an added part in a sentence that is used in relation to the main sentence. However, sometimes a relative clause is so important that the main sentence will be difficult to understand or have no meaning without it. This is called a defining relative clause. On the other hand, we often use a relative clause just to add extra information, which is usually indicated by the use of commas. The meaning of the main sentence will still be clear without it and it is therefore called a non-defining relative clause.  By using commas in written English and a slight pause in spoken English, two identical clauses can have different meanings when used in a sentence.

Choose the correct explanation for each sentence:

1. All my friends who are Asian came to my party.
2. All my friends, who are Asian, came to my party.
3. The Italian restaurant in Long Street got a new owner.
4. The Italian restaurant, which is in Long Street, got a new owner.
5. My cousin who lives in New York is getting married next year.
6. My cousin, who lives in New York, is getting married next year.
7. We study at the only school in Cape Town, which has afternoon lessons.
8. We study at the only school in Cape Town which has afternoon lessons.
9. The book which I finished yesterday was fantastic.
10. The book, which I finished yesterday, was fantastic.
