English Translation
I think I know what’s necessary.
In the sentence “Νομίζω ότι γνωρίζω, τι είναι απαραίτητο,” the comma is not necessary. The correct form would be “Νομίζω ότι γνωρίζω τι είναι απαραίτητο.” The absence of the comma makes the sentence flow more naturally in Greek. The comma could create a pause that is not needed in this context.
