In the examples, there is this sentence: "Ma tante est passée par la boulangerie en venant ici." In the sentence, what purpose does the "en" serve?

Can we not just use ''Elle est ma soeur'' and ''Il est le fils de Martha'' ?

Edit: Nevermind, I asked my French friend who told me that you specifically cannot say 'Il/elle est un/une/mon/ma etc' 

This rule only applies to the pronouns 'Il' (he) and 'Elle' (she). 

So I've answered my previous question, so No you cannot say ''Elle est ma soeur'' it has to be ''C'est ma soeur''

I felt like it wasn't explained very in the lesson! (sorry!)  I hope anyone seeing this message finds this helpful.

Do not we have a vocabulary list of "more common" fruits on kwiziq? 

Why should I say "Je suis UN oncle" instead of "Je suis oncle"? I shall say "Il est président / prof / boulanger", always omitting the indefinite article. Is it different for family relations? Thanks in advance for any help.

I believe six-heures de l'après-midi should be a good option alongside dix-huit heures?
