With everyone in attendance not knowing.

For everyone in attendance did not know.

With everyone attending not knowledgeable.

For not everyone attending knew.

Explanation:

During her lecture, the speaker tried to clarify directional terms, For not everyone attending knew that winds are designed by the direction from which they come.
Something like ‘because’ is needed as the first term in the underlined part. ‘For’ works well.
Option 1 and 3 can be eliminated due to wrong use of ‘with’. They both distort the meaning by changing "Not everyone knew" to "everyone did not know"
option 2 can be eliminated for the awkward use of “in attendance”.
Hence, opiton 4 is the correct answer.
