"duquel" is unacceptable here instead of  "de ce que"

Hello,

I wanted to send a link of this song on this page to my father through the email: do you need a subscrition to "progress with lawless french" to view and hear it?

Why do I sometimes see “l’on” rather than “on” used as a subject?

I opted for "avoir besoin de" here, but "dois" was preferred.  That's okay.  But I had to put a "de" and "le" together.  I did not change it to "du."  Which is correct.  I appreciate your response.

Does "avec eux" refer back to "réunions"? If so, shouldn't you use avec "elles"? Also, Je suis sûre qu'"elles" (meetups) pourront t'aider...

do these adverbs need to agree with the object's gender?

In the sentence in the south of France the answer is le sud but in a previous exercise (Bastille Day) it was du sud.  Are both acceptable ?  Also in the best answer it is C'étaient but in the final paragraph it is C'était.  Are both correct or is this an error?
