Question

Which form of punctuation is best suited for non - restrictive clauses that may include surprising information?

Answer 1

The best suited punctuation for non-restrictive clauses  are commas. The information of the clause can include surprising information.

Examples:

1. My cat, which  loves some vegetables, takes the vegetables from my shopping bag.

     2-My teacher, who has tatoes on his bald head, loves teaching arts.

     3- My teacher , who looks very young,  is very traditional.

The underlined clauses are examples of non- restrictive clauses. They are between commas because we can omit them. If we take them out, the main clauses have meaning, anyway. The information in the non-restrictive clauses can be surprising- look at examples 1 and 2 above -, or not -look at example 3.

Answer 2

The answer would be D or last choice.
