Question

The young child, having been warned by her mother, did not go near the hot stove.

Which of the following best describes the underlined phrase?


essential past participial phrase
essential present participial phrase
nonessential past participial phrase
nonessential perfect participial phrase

Answer 1

If the underlined phrase is having been warned by her mother, then this is a nonessential perfect participial phrase.
Nonessential phrases are separated from the rest of the sentence by commas, and since this is a perfect participle, this is the only correct option.
