All right, I understand the first and the third explanations, but I can't understand the second one. I'm sorry. So, could you please walk me through that?
As for these sentences that you gave me as examples:
- John will be calling in an hour, because he has a question.
- John likes that restaurant the most, because it has the best wine.
I can only see the because-clause as the main point of the sentence, and answer "why" John will be calling or "why" he likes that restaurant the most.
I'm looking forward to hearing from you.
Thank you so much for your patience and time.
