A clause from sentence 1 has been turned into a ______ in sentence 2?

1.Since she knew what the lecture was about, she didn't attend the meeting.

2.Knowing what the lecture was about, she didn't attend the meeting.

My aswer is Relative Pronoun is that correct?
Thank You

"Knowing what the lecture was about" is called a participial phrase in the sentence 2 example, since it functions as a modifier of "she". "Knowing" is a (present) participle. Although "-ing" words are called gerunds, "Knowing what the lecture was about" is not a gerund phrase, because such phrases are used as nouns.

Yes, you are correct. "Knowing what the lecture was about" in sentence 2 is an example of a participial phrase. Participial phrases are phrases that include a present or past participle, such as "knowing" in this case. They function as modifiers in a sentence, providing more information about a noun or pronoun.

In this example, the participial phrase "Knowing what the lecture was about" modifies the pronoun "she," giving us more information about her and why she didn't attend the meeting. Participial phrases can be used to add descriptive details and provide additional information in a sentence.
