Hello,

A clause in sentence 1 has been turned into a pharse in sentence 2. Is this correct?
Thank You

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

2.Knowing what the leture as about, she didn't attend the meeting.

Yes.

Thank you for using the Jiskha Homework Help Forum. Just be sure to check the spelling:
leture = lecture
as = was

Yes, that is correct. In sentence 2, the clause "Since she knew what the lecture was about" has been turned into a phrase "Knowing what the lecture was about." This restructuring keeps the same meaning but condenses it into a shorter form. However, please note that there is a typo in sentence 2. It should be "lecture" instead of "leture" and "was" instead of "as."
