read the sentence.\nthe children, who were lucky, received presents.\nwhich statement accurately describes the sentence?\nthe sentence includes a restrictive clause.\nthe sentence has an appositive that is essential for understanding.\nthe sentence contains a non - restrictive appositive.\nthe sentence describes exactly which children received presents.
Answer
Brief Explanations:
The clause "who were lucky" is set off by commas, which indicates it is a non - restrictive relative clause. A non - restrictive clause gives additional, non - essential information about the noun it modifies. It is not a restrictive clause (which would be essential and not set off by commas), and it's not an appositive. The sentence doesn't precisely single out which children received presents in a restrictive way.
Answer:
The sentence contains a non - restrictive appositive.
